What can Congress do to curb Trump's war powers?
Legal and political tools available to lawmakers
Lawmakers have several formal and informal options to challenge, constrain or shape the president’s use of military force. In the immediate aftermath of an administration incursion that proceeded without congressional approval, Democrats and some Republicans have urged rapid parliamentary action to reassert Congress’s constitutional role over declarations of war.
Practical steps members of Congress can and are pursuing
- A War Powers Resolution vote: Congress can force a floor vote invoking the 1973 statute to require the president to obtain authorization or withdraw forces after a statutory period. Several leaders have already called for such a vote.
- Authorization or denial: Congress can pass a specific authorization for the operation, or a concurrent resolution withdrawing support for further strikes. Either path requires majority votes and, in the Senate, faces filibuster or procedural hurdles.
- Appropriations leverage: The power of the purse offers a long-term check. Lawmakers can withhold or condition defense and discretionary funding, though such measures carry political risk and may be tied up in broader budget fights.
- Oversight and inquiries: Committees can hold hearings, subpoena senior officials, and demand classified briefings to expose the administration’s legal and factual basis for action.
- Political remedies: Pressure campaigns, floor speeches, and public messaging can shape broader party and public opinion, altering the calculus on whether to sustain operations.
The immediate political reality is uncertain. The White House launched strikes without seeking prior authorization; that gives Congress standing to act, but it does not automatically guarantee votes. Bipartisan calls to reconvene and force a vote have gained traction, yet passage depends on internal party dynamics, procedural rules and how quickly opinions shift as new facts about the campaign emerge.
