Iran War and U.S. Congress

Rep. Nancy Mace (R-S.C.) told Axios she will "most likely" vote for House Democrats’ next war powers resolution to constrain President Donald Trump’s authority to wage war with Iran, a notable break with GOP leadership during an ongoing conflict. Mace, who this week also vowed to vote against additional funding for U.S. operations in the region, said in a text that "War with Iran needs to end. President Trump has won the war, time to exit," and added she will not "send South Carolina's sons and daughters into battle to die for the price of oil." An earlier House war powers measure failed 212–219, but several Democrats who opposed it are expected to flip on the next vote, and there is no sign that the two Republicans who previously backed it, Reps. Warren Davidson and Thomas Massie, will reverse course. If Mace joins them and Democrats hold, the resolution could pass the House, creating a high-profile rebuke of Trump’s Iran strategy even though the president could veto it. The move is drawing attention online as an example of growing unease within parts of the GOP about an open-ended Iran campaign and the political risk of being seen as ignoring public opposition to escalation and large ground deployments.
