Congress has yet to approve the process for reviewing a final deal with Iran, but already Republicans are plotting their next move.
Legislation from Sen. Bob Corker, R-Tenn., now being debated on the Senate floor would give lawmakers three options: approve the deal, reject it or do nothing — a tacit endorsement. Rejecting a deal would bar President Barack Obama from lifting congressional sanctions and would almost certainly draw his veto, but many Republicans say they expect their leadership to push for a vote nonetheless.
