Three Democratic lawmakers from the US House of Representatives have introduced a war powers resolution to check President Donald Trump’s use of military force against Iran after US strikes on Tehran’s nuclear sites over the weekend, Reuters reports.

Trump’s Republican Party holds a majority in both the House of Representatives and the Senate, and it is unlikely any resolution restricting Trump’s actions could pass both chambers.

The joint statement issued late on Monday by Democratic U.S. Representatives Jim Himes, Gregory Meeks and Adam Smith came hours after Trump claimed on social media Israel and Iran had agreed to a ceasefire.

“President Trump must not be allowed to start a war with Iran, or any country, without Congressional approval,” the lawmakers said, adding that Trump ordered the strikes “without meaningful consultation or Congressional authorisation.”

House Speaker Mike Johnson said earlier it was not the time to consider a war powers resolution.
