The US Senate rejected a resolution to limit President Trump's war authority over Iran for the fourth time, voting 47-53 along party lines. The vote followed a two-week ceasefire and failed talks in Islamabad. Supporters argue Trump exceeded constitutional authority by launching war February 28 without congressional approval. Republicans defend Trump's actions as presidential duty. The House may vote this week. Under the War Powers Act, Congress must authorize military action by day 60 or approve extension.
