WASHINGTON: Three senior Democratic leaders urged their colleagues in the US Senate on Thursday to support the move to prevent President Donald Trump from continuing the war against Iran without congressional approval.

Democratic Whip Katherine Clark, Minority Leader Hakeem Jeffries, and Caucus Chair Pete Aguilar said in a joint statement that the House of Representatives on Wednesday “successfully passed a War Powers Resolution” and that it is “now time for Senate Republicans to do the right thing.”

They reminded Republican lawmakers that the Iran war has now lasted more than 90 days.

The 90-day period is significant because a US law designed to limit a president’s ability to wage war requires the “president to seek authorisation from Congress if military operations continue beyond that timeframe”.
