The U.S. Congress is set to hold its first votes this week on President Donald Trump's decision to enter a war against Iran, with the Senate and House debating a war powers resolution that would require congressional approval for any further military action. The votes come as the Trump administration faces questions about the goals and strategy of the conflict, which has already resulted in American casualties and is spreading across the Middle East.

Why it matters

The votes in Congress represent a critical test of the balance of power between the legislative and executive branches over matters of war and peace. The debate also highlights the broader public skepticism about entering another open-ended conflict in the Middle East, with lawmakers from both parties expressing concerns about the lack of a clear U.S. exit strategy.

The details

The war powers resolution, if passed, would force Trump to withdraw U.S. troops from the conflict with Iran within 90 days unless Congress authorizes further military action. While the resolution faces an uphill battle in the Republican-controlled Congress and would likely be vetoed by Trump, the votes will still force lawmakers to go on the record about whether they support or oppose the president's decision to enter the conflict without prior congressional approval.

  • The Senate is expected to vote on the war powers resolution on Wednesday, March 4, 2026.
  • The House is scheduled to vote on a similar war powers resolution on Thursday, March 5, 2026.
