The Republican-led US House of Representatives approved a resolution on Wednesday to block President Donald Trump from continuing the war against Iran, reflecting growing concern among members of his party about the three-month-old conflict. The House voted 215 to 208, as four Republicans voted with Democrats in favor of the war powers resolution, according to BusinessWorld .

The measure, which relies on the War Powers Act of 1973, requires the president to withdraw US forces from hostilities within 30 days unless Congress authorizes the conflict. The White House has signaled that Trump would veto the resolution, which would then need a two-thirds majority in both chambers to override.

The Senate is expected to take up a companion resolution in the coming weeks, though its fate remains uncertain. The vote marks a rare bipartisan rebuke of the president’s foreign policy and underscores deepening divisions over the protracted military engagement in Iran.
