Sen.

"This deal isn't perfect and no one trusts Iran, but it has become clear to me that the world is united behind this agreement with the exception of the government of Israel," the Missouri Democrat said in a statement.

"I respect and understand those who oppose it but I have become convinced that it is more dangerous to Israel, America and our allies to walk away in the face of unified world-wide support."


McCaskill is the 26th Senate Democrat to support the agreement, according to The Hill's whip list.

Senate Republicans who are uniformly opposed to the deal are expected to bring a measure of disapproval in September. President Obama has vowed to veto that measure and will need 34 senators to sustain his potential veto and let the deal survive in Congress.

McCaskill added that there is "no certainty" that the five other countries involved in the nuclear negotiations with Iran would reinstate their sanctions regimes if Congress ultimately killed the agreement.

"Instead, I believe it likely that the sanctions regime would fray and nothing would be worse than Iran getting an influx of resources without any agreement in place to limit their ability to get a nuclear weapon," McCaskill added.

The Missouri lawmaker is one of a growing number of Senate Democrats who have thrown their support behind the agreement since Congress left for a five-week recess.

Jamal Abdi, executive director of the National Iranian American Council, quickly praised McCaskill's decision, calling it "another big win" for supporters of the agreement.

"More than half of the Senate Democratic caucus is now on record in support of the nuclear deal," he said in a statement. "It is high time for Senate Democrats who remain on the fence to join their colleagues in public support for the President’s historic diplomatic achievement."

Opponents are hoping to use the break to convince 13 Democrats to buck President Obama and vote against the deal. So far, Sens. Charles Schumer (D-N.Y.) and Robert Menendez (D-N.J.) are the only Democratic no votes in the Senate.

But lawmakers could be under increasing pressure after The Associated Press reported on Wednesday that the International Atomic Energy Agency (IAEA) will allow Iran to use its own experts to investigate any past nuclear weapons work at its Parchin military facility.

The "side deals" between the IAEA and Iran have been a focal point for Republican opposition and Democratic skepticism of the agreement.
