Pa. Sen. Bob Casey becomes 32nd senator to back Iran nuke deal

Democrat Bob Casey of Pennsylvania has become the 32nd senator to support the nuclear deal with Iran.

Casey’s announcement pushes President Barack Obama to within two votes of the 34 needed to sustain a veto of legislation aimed at blocking the deal.

In a statement Tuesday Casey says the deal will “substantially constrain” Iran’s nuclear program and is the best option available.

Earlier Tuesday Sen. Ben Cardin of Maryland, top Democrat on the Foreign Relations Committee, predicted Obama would get to 34 votes by week’s end.
