How To Watch Donald Trump, Sarah Palin And Ted Cruz's Anti-Iran Nuclear Deal Rally In Washington DC: Live Stream

Donald Trump will make his way to Washington on Wednesday afternoon, and he's bringing former Republican vice presidential nominee Sarah Palin and Texas Sen. Ted Cruz with him to protest the Iran nuclear deal. Trump and the other politicians will congregate on Capitol Hill to speak out against the agreement in a rally that is expected to draw thousands.

The rally comes in response to news Tuesday that President Barack Obama has secured enough support in the Senate to block a Republican resolution disapproving the deal. Republicans have condemned the agreement, arguing the deal will not prevent Iran from obtaining nuclear weapons. They have also raised concerns about the deal's provisions to lift economic sanctions against Iran.

Trump, a GOP presidential candidate, vowed on Fox News Channel's "The O'Reilly Factor" Tuesday to renegotiate the deal if he is elected president.

"That deal is a disgrace," Trump said. "It should have never been allowed. And how Obama got away with it is beyond anybody's comprehension."

Wednesday's speaker roster runs deep: It includes former Virginia Gov. Jim Gilmore; conservative talk show host Mark Levin; radio host Glenn Beck; David Bossie, president of Citizens United; and U.S. Reps. Dave Brat of Virginia, Jim Bridenstine of Oklahoma, Trent Franks of Arizona and Mike Pompeo of Kansas.

Jenny Beth Martin, a co-founder of the Tea Party Patriots, has been one of the driving forces behind the rally. She called Americans to action while on Michael Boyle's "Breitbart News Sunday" radio show.

"We need people to be there, and to show up, and to make their voice heard, and to let Congress know that the American people are against this deal," Martin said.

Martin said more than 70 people have approached her to speak Wednesday, McClatchy News reported.

The rally will be available to watch online for free at 1 p.m. EDT on LiveStream.
