Two more key Democratic senators announced their support Tuesday for the Iran nuclear deal, all but ensuring that President Obama will have enough votes to uphold the polarizing accord despite almost unanimous opposition from Republicans.
Congress is set to vote by Sept. 17 on a resolution to disapprove the deal. Consideration of the agreement has become an increasingly partisan exercise as Republicans line up against it, leaving the outcome largely in the hands of wavering Democrats.
The deal would curb Iran's ability to enrich uranium for 15 years in exchange for easing of international sanctions. The White House argues the deal cuts off Iran's ability to build a nuclear bomb, should it choose to do so, while critics contend the sanctions relief will strengthen a government that sponsors terrorism.
