The House of Representatives voted Wednesday to pass a War Powers Resolution directing the end of U.S. military operations against Iran, marking the most significant congressional challenge yet to the Trump administration's military campaign. The resolution passed with a bipartisan majority, though the White House has signaled opposition to any effort to curtail the operation.

The Congressional Budget Office estimated the conflict has cost approximately $38 billion to date, with projections warning that costs could climb significantly higher depending on the duration and scope of continued engagement. The CBO's figures have added urgency to the congressional debate over whether the executive branch requires explicit authorization to sustain the military campaign.

Inside Iran, protests have intensified in recent days, with citizens in multiple cities demonstrating against the government of Supreme Leader Ayatollah Khamenei. The unrest has complicated the geopolitical picture, with some analysts arguing that domestic instability within Iran creates both risks and opportunities for U.S. policy.

The War Powers Resolution now faces an uncertain path in the Senate, where it is unclear whether it commands the votes needed to advance. Even if it passes both chambers, President Trump would likely veto the measure, and overriding that veto would require a two-thirds majority in each chamber — a threshold considered difficult to reach given current vote counts.

The debate over the conflict has also intersected with broader domestic political developments, including a Supreme Court ruling on mail-ballot procedures that drew criticism from the president. Supporters of the war powers measure argue that Congress has a constitutional obligation to weigh in regardless of the outcome of other political battles, while administration allies contend that the resolution undermines military strategy at a critical moment.
