The United States House of Representatives has narrowly rejected a war powers resolution that would have halted President Donald Trump’s war on Iran and required congressional authorisation for any further attacks.
The vote on Thursday was 219 to 212 in the House, where Trump’s fellow Republicans control a narrow majority of seats.

Mast, an army veteran who worked as a bomb disposal expert in Afghanistan, said the war powers resolution was effectively asking “that the president do nothing”.
However, after launching a surprise attack against Iran on Saturday, Trump has scrambled to win support for the war on Iran, a conflict Americans of all political persuasions were already wary of entering.
Trump administration officials spent hours behind closed doors on Capitol Hill this week trying to reassure lawmakers that they have the situation under control.
Six US military members were killed over the weekend in a drone strike in Kuwait, and Trump has said more Americans could die.
