"In weighing everything, all the information, I've concluded the best thing to do is vote in support of the Iran deal and put Iran years away from being a nuclear state," Wasserman Schultz, the first Jewish-American woman to represent Florida in Congress, told CNN on Sunday.
Schultz added that her decision to endorse the accord came after she was briefed on the agreement two dozen times in the White House's Situation Room.
President Obama needs 41 votes in the Senate to filibuster procedural rule to prevent a resolution disapproving the accord. So far 38 Democrats have come out in support of the agreement.
If the resolution is filibustered, it would be a major victory for the White House, which wouldn’t have to use President Obama’s veto pen to protect the Iran deal.
Iran and the Group 5+1 (Russia, China, the US, Britain, France and Germany- also known as P5+1 or E3+3) finalized the text of lasting deal on Tehran’s nuclear program on July 14.
When Congress returns to Capitol Hill from its August recess after Labor Day, both the House and Senate are expected to vote on resolutions disapproving the July 14 accord.
