Republican lawmakers: Nuclear deal won’t last without congress’s signoff

Forty-seven US Republican senators warned Iran's leaders on Monday that a nuclear deal needs congressional approval to survive past President Barack Obama's term – their answer to Obama’s intention to veto any motion calling for a review of a nuclear accord prior to its approval.. Without congressional approval, the senators pointed out, Tehran would be left with an “executive agreement” between President Obama and Iran’s leaders. The next president could revoke it with a stroke of a pen, and future congresses could modify its terms any time.
