Donald Trump is coming to Washington with a message for Congress and the American people: Stop the nuclear deal with Iran. And he will be joined by a star-studded galaxy of conservative leaders. Appearing with the leading Republican presidential contender will be fellow candidate Sen. Ted Cruz, R-Texas, former Gov. Sarah Palin, R-Alaska, political commentator Glenn Beck, radio talk-show host Mark Levin and many others in what promises to be a huge rally to try stop the Iran deal at the Capitol on Wednesday.
