The second White House official, John Bisognano, went on to stress “the importance of this to the president.”

“This is clearly an issue that is very close to his heart and something that’s extraordinarily important for the future of frankly the world,” Bisognano said. “I want to make sure everyone understands this is a top priority for the administration, and this is clearly something that we’re all focused on moving forward and excited about hoping that we can come to a solid agreement.”

Leaders of the call emphasized that the assembled groups should target Democrats in order to build a veto-proof majority when the deal eventually comes to Congress for a vote.

Robert Creamer, a member of the liberal political shop Democracy Partners and the general consultant to the anti-Republican Americans United for Change, urged participants on the call to “step up” their pro-Iran efforts.
