US Representatives Thomas Massie and Ro Khanna have sponsored a resolution that calls on Trump to “terminate” the use of US armed forces against Iran unless “explicitly authorised” by a declaration of war from Congress.

“No president should be able to bypass Congress’s constitutional authority over matters of war,” Khanna, a Democrat from California, said in a statement.

“The American people do not want to be dragged into another disastrous conflict in the Middle East.”

More than a dozen Democratic lawmakers signed onto the bill as a co-sponsor.

Massie, from Kentucky, is the only Republican on the bill so far.

“The ongoing war between Israel and Iran is not our war,” Massie said.

“Even if it were, Congress must decide such matters according to our Constitution.”

A vote on the resolution is not imminent as the House is out of Washington this week.
