The United States House of Representatives narrowly rejected a resolution aimed at limiting President Donald Trump’s authority to wage war against Iran. The measure failed by a single vote, 214 to 213, following a similar defeat in the Senate the previous day. The vote reflected growing unity among Democrats, with three members switching to support the resolution, while only one Republican, co-sponsor Thomas Massie, voted in favor. The outcome underscored continued Republican resistance to restricting Trump’s military powers as the conflict with Iran entered its sixth week.

Democrats accused Republicans of granting Trump unchecked power after he and Israel launched strikes on Iran on February 28. They argued that the president was exceeding constitutional limits, while Trump’s administration maintained that Iran’s actions since 1979 justified self-defensive measures. Ceasefire negotiations remain ongoing, with the US and Iran considering renewed talks in Pakistan after earlier efforts failed. Trump also announced a 10-day pause in Lebanon fighting, though Hezbollah’s participation was unclear.

Pentagon chief Pete Hegseth said the US was prepared to resume attacks on Iran’s energy facilities if diplomacy failed. The antiwar group Demand Progress criticized both parties for neglecting Congress’s constitutional duty and urged renewed diplomatic efforts to end the conflict.
