The House is set to vote on a resolution that could halt U.S. military action against Iran, potentially defying President Trump as bipartisan support for ending the conflict grows. This move comes amid increasing opposition to the three-month-long war, with some Republicans joining Democrats in backing the resolution. House Speaker Mike Johnson has previously tried to block such a vote, but the mounting dissent shows the significant political stakes involved in this decision, highlighting the broader debate over executive power and congressional oversight in military engagements.
