Big-name Republicans like Senator Ted Cruz, Donald Trump and others plan to protest at the Capitol on Wednesday against the Iran nuclear deal.

“The message, I think, from many of the speakers will be that this deal funds and arms the Nazi Germany of today,” Morton Klein, president of the Zionist Organization of America, a co-sponsor of the rally, said.

“We’re going to be urging those [supporting the deal] to rethink their position and try to make them recognize the future blood of innocent civilians who will be massacred because of this deal will be on their hands,” he said. “Many of us will say it that bluntly.”

Hillary Clinton is expected to give a speech of support for the Iran nuclear deal.

“Clinton will make the case that this deal – combined with vigorous enforcement and a comprehensive regional strategy for countering Iran – is the best and most effective way to prevent Iran from acquiring a nuclear weapon,” said Clinton’s campaign.

Also in attendance will be Sarah Palin and Glenn Beck along with Representatives Steve King and Louie Gohmert.
