Senator Brian Schatz (D-HI) said on Monday he backs the nuclear deal with Iran, becoming the 16th senator to do so and moving President Barack Obama one vote closer to locking in enough Senate votes to make the deal fly, Reuters reported.
A liberal, Jewish-born lawmaker from Hawaii, Schatz had been expected to come down in favor of the deal. His decision is noteworthy because it came just a few days after another Jewish senator, Democrat Chuck Schumer of New York, announced his opposition to the Iran agreement.
Schumer's decision last week caused an uproar as he usually lines up behind the president, though White House spokesman Josh Earnest said on Friday that the decision was "disappointing but not surprising".
Schumer is the No. 3 senator and wants to become Senate Democratic leader after the 2016 election.
In a statement, Schatz said he was backing the pact between six world powers and Iran because it is the best option for keeping nuclear bombs out of Tehran's hands.
"Iran must never be allowed to have a nuclear weapon, and that is why I support this agreement," Schatz said, according to Reuters.
Most Republicans have also said they oppose the deal, which was unveiled on July 14. It is designed to curb Tehran's nuclear program in exchange for lifting of economic sanctions.
Republicans plan to push for a congressional "resolution of disapproval" that could cripple the deal. Obama is pinning his hopes on Democrats, in the minority in both houses of Congress.
Schatz said no military option could do what the agreement would do – deny Iran a bomb for at least 15 years.
"This agreement should not be compared to an imaginary deal where Iran rolled over and eliminated all its centrifuges and all peaceful nuclear energy generation. That was never seriously on the table," he was quoted as having said.
Leading Democratic Reps. Nita Lowey and Steve Israel, both of New York, and Ted Deutch of Florida last week announced their opposition to the Iran deal.
Congress has until Sept. 17 to vote on any resolution of disapproval of the agreement. After Schumer's announcement last week, Democrats said they were still confident they could rebuff Republican attempts to sink the agreement.
Obama, for his part, has threatened to veto any legislation passed by Congress blocking the deal.
