Sen. Mark Warner (D-Va.) said Thursday that he intends to support the Obama administration’s nuclear deal with Iran. 

“I believe that supporting the Joint Comprehensive Plan of Action (JCPOA) negotiated between Iran and the United States, the United Kingdom, France, Germany, Russia and China is the best option for advancing the goal of keeping Iran from obtaining a nuclear weapon,” the senator said in a statement.

“While I believe there are several areas of concern with the agreement, the choice I ultimately had to make was between accepting an imperfect deal, or facing the serious ramifications if Congress rejected a deal that has the support of the rest of the world,” he added. “This agreement is just the beginning, and not the end, of our combined international efforts to keep Iran free of nuclear weapons.”

Warner’s support brings the number of Senate Democrats backing the deal to 36, two more than is needed to sustain a presidential veto of a resolution disapproving of the deal, according to The Hill. If the number of supporters reaches 41, they will be able to filibuster the resolution and avert the need for a veto.

Sen. Cory Booker (D-N.J.) also said Thursday that he would support the Iran nuclear deal, which he said was the better of “two imperfect, dangerous and uncertain options.”

“We have now passed a point of no return that we should have never reached, leaving our nation to choose between two imperfect, dangerous and uncertain options,” Booker stated. “Left with these two choices, I nonetheless believe it is better to support a deeply flawed deal, for the alternative is worse. Thus, I will vote in support of the deal.”
