What can Congress do about war powers?

Tools available to lawmakers and political realities

Congress has several constitutional and statutory tools to respond to presidential military action. The Biden‑era debates over the War Powers Resolution resurfaced: lawmakers can compel a vote to withdraw forces, pass new authorization language, withhold funding, or use oversight hearings to shape public pressure and legal constraints. In the days after the strikes, leaders in both parties moved to force votes on measures intended either to terminate the president’s authority to continue strikes without congressional approval or to clarify and authorize specific operations.

Options on the table

• Pass a resolution under the War Powers Resolution to end hostilities or require withdrawal
• Introduce and vote on fresh Authorization for Use of Military Force (AUMF) language to grant or limit action
• Use appropriations power to deny funding for particular operations or sustainment
• Hold oversight hearings, subpoena documents and call administration officials to testify

Practical limits and pitfalls

Passing legislation requires a majority in both chambers, and the president can veto bills he opposes. Even when Congress coalesces around a measure, procedural hurdles in the Senate—filibusters and timetables—can block votes. Political dynamics matter: some Republicans and Democrats supported the strikes, reducing the margin for a successful limiting measure. Courts rarely resolve interbranch war‑powers disputes quickly, so Congress’s most immediate leverage is legislative: voting and funding. Lawmakers are also mindful that a late vote to constrain the president can produce politically fraught choices for incumbents in an election year.

Why this matters now

A prompt congressional response will shape the legal framework for any further action, determine funding and oversight, and influence international perceptions. Absent clear, durable authorizing language, the action will continue to produce legal and political controversy and could set new precedents about when and how presidents deploy U.S. forces abroad.
