WASHINGTON (AP) — Republican senators are insisting that the House and Senate sign off on any potential nuclear deal between Iran and six world powers or else sanctions on Tehran that had been temporarily lifted could kick back in.

Sen. Bob Corker of Tennessee, the top GOP senator on the Foreign Relations Committee, joined with four other senators Wednesday in introducing legislation that says President Barack Obama must submit any nuclear deal with Iran to Congress within three days. The House and Senate would then vote on the deal.

If the president failed to submit the agreement, sanctions would be reimposed.

The six world powers, including the United States, and Iran extended their negotiations to Nov. 24 after failing to reach a deal.

Corker’s legislation faces an uncertain fate in the Democratic-led Senate.
