WAR-001 — War Powers and Use-of-Force Authorization Reform Act

A BILL

To amend and strengthen the War Powers Resolution, the framework governing authorizations for use of military force, and related appropriations and reporting rules by clarifying when congressional authorization is required before the introduction of United States Armed Forces into hostilities, defining covered hostilities, offensive hostilities, and emergency defensive action, requiring legal-basis certification and reporting, preventing appropriations from being treated as implied authorization, establishing funding consequences for unauthorized hostilities, requiring specificity and sunset rules for authorizations for use of military force, requiring information and legal-interpretation access for Congress, preventing mission expansion beyond authorization, and for other purposes.

Be it enacted by the Senate and House of Representatives of the United States of America in Congress assembled,

SECTION 1. SHORT TITLE.

This Act may be cited as the “War Powers and Use-of-Force Authorization Reform Act.”

SEC. 2. PURPOSES.

The purposes of this Act are to—

  1. preserve Congress's constitutional role in authorizing war and significant military hostilities;
  2. preserve the President's ability to repel sudden attacks, protect United States persons from imminent harm, and respond to genuine exigencies;
  3. prohibit the President from initiating offensive hostilities without specific statutory authorization;
  4. require prior statutory authorization for non-emergency offensive or discretionary hostilities;
  5. clarify the meaning of hostilities, offensive hostilities, emergency defensive action, and covered military operations;
  6. strengthen the standards governing authorizations for use of military force;
  7. prevent stale, overbroad, indefinite, or mission-shifted authorizations from serving as open-ended authority for new hostilities;
  8. ensure rapid reporting and legal-basis certification when emergency defensive action is taken;
  9. ensure that Congress receives sufficient information before voting on, renewing, expanding, or funding significant uses of force;
  10. require disclosure or controlled congressional access to material executive-branch legal interpretations supporting hostilities;
  11. prevent mission expansion beyond the enemy, geography, mission, duration, and operational scope authorized by Congress;
  12. prevent appropriations, procurement, logistics support, or general defense funding from being treated as implied authorization for hostilities unless Congress expressly so provides;
  13. create clear termination, withdrawal, and funding consequences for unauthorized hostilities;
  14. provide Congress with expedited procedures for authorizing, disapproving, limiting, or terminating covered operations; and
  15. create statutory consequences capable of operating even where judicial enforcement is uncertain.

SEC. 3. DEFINITIONS.

In this Act:

(a) Armed Forces.

The term “United States Armed Forces” includes any member, unit, component, command, contractor-operated military force under operational military control, or other armed force acting under the command, operational control, or direction of the United States.

(b) Hostilities.

The term “hostilities” means any situation in which United States Armed Forces are engaged in, authorized to engage in, or exposed to a substantial risk of armed conflict, including kinetic strikes, exchange of fire, targeting operations, combat patrols, offensive cyber operations with reasonably foreseeable destructive effects, detention or capture operations, deployment into an active combat zone, or mission support integral to ongoing combat.

(c) Offensive hostilities.

The term “offensive hostilities” means any use of United States Armed Forces to initiate, escalate, punish, retaliate, deter, coerce, degrade, disrupt, destroy, occupy, seize, capture, compel, prevent a speculative future threat, alter another state or non-state actor's conduct, or achieve strategic, political, or military objectives beyond emergency defensive action.

Offensive hostilities include punitive retaliation, reprisal strikes, deterrent strikes, coercive diplomacy, preventive war, regime-change operations, degradation campaigns, extended interdiction campaigns, occupation, seizure of territory, sustained targeting campaigns, and operations primarily intended to alter the conduct or capacity of a foreign state, organization, or armed group.

(d) Emergency defensive action.

The term “emergency defensive action” means a use of force that is necessary and limited to—

  1. repel an actual armed attack against the United States, United States Armed Forces, or United States persons;
  2. prevent an imminent armed attack where the threat is specific, concrete, and temporally urgent;
  3. rescue or protect United States persons from imminent serious bodily harm or hostage-taking; or
  4. evacuate United States persons from an imminent threat environment where the use of force is limited to protection of the evacuation.

Emergency defensive action does not include punitive retaliation, reprisal, deterrence, coercion, preventive war, degradation of an adversary's general capabilities, regime change, occupation, seizure of territory, extended interdiction, or any broader military campaign unless Congress has enacted specific statutory authorization.

(e) Anti-relabeling rule.

A use of force is not emergency defensive action merely because the executive branch describes it as limited, targeted, defensive, preemptive, deterrent, counterterrorism, force protection, national security, stability, humanitarian, or necessary to preserve credibility.

The classification of an operation depends on the operation's objective, factual predicate, scope, duration, and reasonably foreseeable effects, not on the label assigned by the executive branch.

(f) Introduction into hostilities.

The term “introduction into hostilities” includes the deployment, assignment, authorization, operational control, or use of United States Armed Forces in hostilities, imminent hostilities, offensive hostilities, emergency defensive action, or a covered military operation.

(g) Imminent hostilities.

The term “imminent hostilities” means circumstances in which armed conflict involving United States Armed Forces is clearly likely within a short and identifiable time period based on specific operational facts, not merely generalized geopolitical risk, speculative threat assessment, long-term strategic risk, deterrence rationale, or desire to preserve future military advantage.

(h) Covered military operation.

The term “covered military operation” means any use of United States Armed Forces that involves hostilities, imminent hostilities, offensive hostilities, emergency defensive action, combat support integral to hostilities, or introduction into a foreign state's territory, airspace, waters, or cyber infrastructure in a manner reasonably likely to produce armed conflict.

(i) Specific statutory authorization.

The term “specific statutory authorization” means an Act of Congress, joint resolution, or other law enacted through bicameralism and presentment that expressly authorizes the covered military operation and satisfies the specificity requirements of section 10.

(j) Unauthorized hostilities.

The term “unauthorized hostilities” means hostilities, offensive hostilities, or a covered military operation not authorized by specific statutory authorization and not justified as emergency defensive action within the period permitted by this Act.

(k) Material mission expansion.

The term “material mission expansion” means any material change in the enemy, target, associated force, geography, mission objective, duration, operational method, level of force, or legal theory for a covered military operation beyond the scope expressly authorized by Congress.

The term “material legal interpretation” means any executive-branch legal opinion, memorandum, directive, finding, or formal legal analysis that substantially supports, expands, narrows, or reclassifies the asserted legal authority for hostilities, emergency defensive action, an authorization for use of military force, mission expansion, or continued operations.

SEC. 4. PRIOR AUTHORIZATION REQUIREMENT.

(a) Rule.

Except for emergency defensive action under section 5, the President may not introduce United States Armed Forces into hostilities, imminent hostilities, offensive hostilities, or a covered military operation unless Congress has enacted specific statutory authorization.

(b) Express prohibition on unilateral offensive hostilities.

The President may not initiate offensive hostilities without specific statutory authorization.

(c) No authorization by implication.

No treaty, appropriations measure, procurement authorization, intelligence authorization, logistical support authorization, general defense authorization, or statement of policy shall constitute specific statutory authorization unless Congress expressly states that the provision authorizes hostilities for purposes of the War Powers Resolution and this Act.

(d) Existing constitutional authority preserved only for emergency defense.

Nothing in this section prevents the President from taking emergency defensive action under section 5.

SEC. 5. EMERGENCY DEFENSIVE ACTION.

(a) Authority.

The President may undertake emergency defensive action without prior specific statutory authorization only where the action satisfies the definition in section 3(d) and is limited in scope, duration, and geography to the exigency requiring immediate action.

(b) No offensive conversion.

Emergency defensive action may not be converted into offensive hostilities, punitive retaliation, coercive diplomacy, preventive war, prolonged detention operations, occupation, degradation of general adversary capability, regime change, or a broader military campaign without specific statutory authorization.

(c) Burden of classification.

In any report, certification, or request under this Act, the President shall identify whether an operation is emergency defensive action, offensive hostilities, or specifically authorized hostilities, and shall state the facts supporting that classification.

(d) Duration.

Emergency defensive action may continue without specific statutory authorization for no more than 7 days unless Congress authorizes continuation by law.

(e) Withdrawal and limitation.

If Congress does not enact specific statutory authorization within the period specified in subsection (d), the President shall terminate offensive activity and withdraw or limit forces to the minimum defensive posture necessary to protect United States personnel during withdrawal.

(a) Certification before action where practicable.

Before introducing United States Armed Forces into hostilities, imminent hostilities, offensive hostilities, or a covered military operation, the President shall transmit to Congress a written legal-basis certification.

(b) Emergency certification.

If prior certification is not practicable because of emergency defensive action, the President shall transmit the certification not later than 24 hours after initiation of the action.

(c) Contents.

The certification shall include—

  1. the factual basis for the operation;
  2. the legal basis asserted;
  3. whether the action is based on specific statutory authorization, emergency defensive action, or another asserted authority;
  4. whether the operation involves offensive hostilities;
  5. the enemy, target, or threat addressed;
  6. the geographic scope;
  7. the mission objective;
  8. the expected duration;
  9. the expected scope of hostilities;
  10. the anticipated risk to United States Armed Forces and civilians;
  11. the appropriations account or funding source to be used;
  12. whether Congress has been asked to enact specific statutory authorization; and
  13. the planned termination or withdrawal schedule absent authorization.

(d) Public and classified versions.

The President shall transmit a classified version where necessary and shall also make public an unclassified version containing as much information as can be disclosed consistent with national security.

SEC. 7. REPORTING DURING HOSTILITIES.

For any hostilities, imminent hostilities, offensive hostilities, covered military operation, or emergency defensive action, the President shall provide updated reports to Congress at least every 7 days until the operation is terminated or specifically authorized by Congress.

Each report shall state whether the operation remains within its original legal basis, whether mission scope has changed, whether additional authorization is requested, whether the operation involves offensive hostilities, and whether termination or withdrawal is planned.

SEC. 8. AUTOMATIC TERMINATION AND WITHDRAWAL.

(a) Termination rule.

Hostilities, emergency defensive action, or a covered military operation not supported by specific statutory authorization shall terminate upon the earliest of—

  1. expiration of the emergency defensive action period under section 5(d);
  2. expiration of any time limitation contained in a specific statutory authorization;
  3. enactment of a law terminating, prohibiting, or limiting the operation;
  4. a determination by the President that the operation no longer falls within its certified legal basis; or
  5. a material mission expansion not authorized under section 13.

(b) Meaning of termination.

Termination requires cessation of offensive activity, targeting, combat patrols, strikes, detention or capture operations, and combat support integral to hostilities, except as necessary for safe and orderly withdrawal, emergency rescue, medical evacuation, or force protection during withdrawal.

(c) Withdrawal plan.

Upon a termination trigger, the President shall transmit to Congress, not later than 24 hours after the trigger, a withdrawal or limitation plan stating the steps, timeline, force-protection measures, and legal basis for any continued presence.

(d) No slow-walking.

The withdrawal or limitation plan shall be executed as expeditiously as safely practicable. Force protection may not be used as a pretext to continue offensive hostilities or sustain the unauthorized mission.

SEC. 9. FUNDING LIMITATION FOR UNAUTHORIZED HOSTILITIES.

(a) Prohibition.

No funds appropriated or otherwise made available by any Act of Congress may be obligated or expended for unauthorized hostilities after the applicable authorization period expires or a termination trigger occurs.

(b) Permitted uses.

After the authorization period expires or a termination trigger occurs, funds may be used only for—

  1. safe and orderly withdrawal;
  2. protection of United States personnel during withdrawal;
  3. rescue of United States persons;
  4. medical evacuation;
  5. force protection necessary to end the unauthorized operation; and
  6. activities expressly authorized by subsequent law.

(c) No waiver.

The funding limitation in this section may not be waived by the President.

(d) Agency compliance.

No officer or employee of the United States may knowingly obligate or expend funds in violation of this section.

SEC. 10. SPECIFICITY AND SUNSET REQUIREMENTS FOR AUTHORIZATIONS FOR USE OF MILITARY FORCE.

(a) Required elements.

No authorization for use of military force enacted after the date of enactment of this Act shall constitute specific statutory authorization unless it expressly states—

  1. the enemy, target, or covered opposing force;
  2. any associated force covered by the authorization;
  3. the geographic scope;
  4. the authorized mission objective;
  5. the forms of force authorized;
  6. the reporting obligations applicable to the operation;
  7. the sunset date;
  8. the conditions for renewal; and
  9. that the authorization constitutes specific statutory authorization for purposes of the War Powers Resolution and this Act.

(b) Sunset.

An authorization for use of military force enacted after the date of enactment of this Act shall expire not later than 2 years after enactment unless Congress expressly provides for an earlier expiration or renews the authorization by law.

(c) Renewal.

Renewal requires an Act of Congress enacted through bicameralism and presentment and shall not occur by implication, appropriation, or continuing resolution unless the renewal language expressly satisfies subsection (a).

(d) Associated forces.

No associated force, successor force, splinter force, or affiliated organization may be treated as covered unless Congress expressly identifies the force or establishes a specific process for identifying such force and receives notice and an opportunity for expedited disapproval.

(e) No geographic or mission drift.

An authorization may not be construed to cover operations in a country, theater, mission, or method of force not within the express geographic and mission scope of the authorization.

SEC. 11. PRE-AUTHORIZATION INFORMATION REQUIREMENTS.

(a) Information required before authorization vote.

Before either House votes on a bill or joint resolution providing, renewing, or materially expanding specific statutory authorization, the President shall transmit to Congress, to the extent practicable and consistent with national security, a report containing—

  1. the legal basis for the proposed authorization;
  2. the factual and intelligence basis for the proposed use of force;
  3. the identified enemy, target, or associated force;
  4. the proposed geographic scope;
  5. the proposed mission objective;
  6. the expected duration;
  7. the expected forms and intensity of force;
  8. the anticipated escalation risks;
  9. the anticipated civilian-harm risks;
  10. the anticipated cost and funding source;
  11. alternatives to force considered;
  12. allied or coalition participation;
  13. expected criteria for success;
  14. expected exit or transition criteria; and
  15. material legal interpretations supporting the proposed authorization.

(b) Classified annex.

Information that cannot be publicly disclosed shall be provided in a classified annex to the appropriate committees and congressional leadership, with procedures sufficient to permit meaningful review before a vote.

(c) Emergency exception.

This section does not prevent emergency defensive action under section 5, but any subsequent request for authorization shall comply with this section.

The President shall transmit to the congressional intelligence, armed services, foreign affairs, and appropriations committees, and to the congressional leadership, any material legal interpretation supporting—

  1. the introduction of United States Armed Forces into hostilities;
  2. classification of an operation as emergency defensive action;
  3. continued hostilities after an emergency period;
  4. reliance on an authorization for use of military force;
  5. identification of an associated or successor force;
  6. material mission expansion; or
  7. the conclusion that appropriations or related legislation authorizes hostilities.

(b) Timing.

Material legal interpretations shall be transmitted before action where practicable and, in any event, not later than 7 days after the relevant operation, classification, or legal determination.

(c) Classified or privileged material.

The President may provide classified or appropriately protected versions where necessary, but shall provide sufficient detail to permit Congress to understand the operative legal theory.

(d) No secret expansion.

No undisclosed material legal interpretation may be relied on to expand the enemy, geography, mission, duration, or scope of a covered military operation beyond the public or classified authorization provided to Congress.

SEC. 13. MISSION EXPANSION AND MATERIAL CHANGE.

(a) Reauthorization required.

The President may not undertake a material mission expansion without specific statutory authorization for that expansion.

(b) Notice.

If the President determines that a material mission expansion may be necessary, the President shall notify Congress not later than 48 hours after the determination and shall state the factual, legal, operational, and funding basis for the proposed expansion.

(c) No expansion by operational necessity.

Operational convenience, strategic advantage, deterrence, coalition preference, or force protection may not by itself authorize a material mission expansion.

(d) Emergency defense preserved.

Nothing in this section prevents emergency defensive action under section 5, provided that such action does not become a broader unauthorized mission.

SEC. 14. EXPRESS AUTHORIZATION REQUIREMENT FOR APPROPRIATIONS.

An appropriation, authorization of appropriations, procurement law, logistical support law, intelligence authorization, continuing resolution, supplemental appropriation, or defense authorization shall not constitute authorization for hostilities unless it expressly states:

“Congress specifically authorizes hostilities for purposes of the War Powers Resolution and the War Powers and Use-of-Force Authorization Reform Act.”

General support for members of the Armed Forces, equipment, logistics, pay, benefits, evacuation, medical care, force protection, intelligence, or withdrawal shall not be construed as authorization for hostilities.

SEC. 15. EXPEDITED CONGRESSIONAL PROCEDURES.

(a) Authorization request.

If the President requests specific statutory authorization for a covered military operation, each House shall have procedures for expedited consideration, debate, and vote.

(b) Disapproval or limitation measure.

A bill or joint resolution to prohibit, limit, terminate, or condition a covered military operation shall receive expedited consideration under procedures established by each House.

(c) Minority-triggered review.

Each House may establish procedures allowing a qualifying minority of members, or a qualifying minority of members of a relevant committee, to require a hearing, report, or privileged motion concerning hostilities, emergency defensive action, authorization renewal, termination, mission expansion, or funding limits under this Act.

(d) Presentment.

Any bill or joint resolution creating binding legal consequences under this Act shall be presented to the President under Article I, Section 7 of the Constitution.

(e) Veto override preserved.

If the President vetoes a bill or joint resolution under this section, Congress may enact the measure by overriding the veto with a two-thirds vote of both Houses.

SEC. 16. RULE AGAINST CONCURRENT-RESOLUTION TERMINATION.

No concurrent resolution or simple resolution shall be treated as creating binding legal consequences under this Act. Congress may express its judgment by concurrent or simple resolution, but binding authorization, prohibition, limitation, or termination of hostilities shall proceed through constitutionally required legislative procedures.

SEC. 17. RELATION TO EXISTING AUTHORIZATIONS.

Nothing in this Act repeals an existing authorization for use of military force. However, no existing authorization may be construed to authorize a covered military operation unless the operation falls within the enemy, target, mission, geography, and temporal scope of that authorization.

Not later than 180 days after enactment, the President shall transmit to Congress a report identifying each existing authorization for use of military force on which the executive branch relies, the operations conducted under each authorization, the enemy or associated force covered, the geographic scope, the mission objective, and any material legal interpretation supporting the scope of reliance.

SEC. 18. RULE OF CONSTRUCTION.

Nothing in this Act shall be construed to—

  1. authorize hostilities not otherwise authorized by law;
  2. limit Congress's constitutional power to declare war or authorize force;
  3. limit Congress's power of the purse;
  4. prevent emergency defensive action satisfying section 5;
  5. authorize unilateral offensive hostilities;
  6. permit hostilities based solely on appropriations by implication;
  7. impair laws governing covert action, intelligence oversight, or classified reporting, except that such laws shall not be treated as implied authorization for hostilities; or
  8. affect the authority of Congress to enact more restrictive limits on the use of military force.

SEC. 19. SEVERABILITY.

If any provision or application of this Act is held invalid, the remainder shall not be affected.

Budgetary Impact Statement

Administrative workload is possible; no new appropriation is specified.

Note: Preliminary ARRP assessment only; not a CBO, OMB, agency, or legislative-counsel score.

Drafting Notes

  • This is the first working draft for the collapsed A-03 issue.
  • WAR-002 through WAR-008 have been collapsed into WAR-001 as component defects rather than standalone legislative vehicles.
  • The draft now contains operative provisions addressing initiation, emergency defense, anti-relabeling, automatic termination and withdrawal, funding consequences, AUMF specificity and sunsets, pre-authorization information, executive legal-interpretation access, mission expansion, appropriations-as-implied-authorization, expedited procedures, presentment, and concurrent-resolution limits.
  • The emergency defensive window is set at 7 days as a provisional drafting choice and requires policy review.
  • The two-year default AUMF sunset is provisional and requires policy review.
  • The definitions of hostilities, offensive hostilities, emergency defensive action, and covered military operation require comparison against prior reform bills, OLC opinions, and operational categories.
  • Binding legal consequences require bicameralism and presentment. Veto override remains constitutionally available.
  • The central principle is that the President may act alone to defend against immediate harm but may not act alone to initiate, punish, deter, coerce, degrade, or reshape foreign actors through offensive military force.
  • This draft is designed to create legal, political, appropriations, reporting, and internal executive-branch consequences even where courts decline to adjudicate war-powers disputes.
