Michael Steel, a spokesman for Boehner, confirmed that the speaker said he did not expect Congress to have the votes to overturn a veto of a resolution to disapprove the Iran deal. “Obviously, it takes only a fraction of the House and Senate Democrats to sustain a veto,” Steel told me. “But it is impossible to say whether they will or not until we know what the final ‘deal’ looks like.”

One Republican elected official who attended the Republican Jewish Coalition’s weekend event told me many attendees were disappointed in Boehner’s prediction. “It seems like Congress can’t do anything to stop Obama’s Iran deal,” the official said. Others who went to the Boehner event expressed a similar concern to me as well.

Several Republican politicians in Las Vegas weekend were also wary of the Iran negotiations. Rick Perry, the former governor of Texas who may seek the presidency, told the audience that the agreement being negotiated “doesn’t limit Iran’s nuclear program, it legitimizes it.” Senator Ted Cruz, the Texas Republican who announced this month that he was running for president, pledged: “I will do everything humanly possible to stop a bad Iran deal.”
