Senate Majority Leader Harry Reid slamming a former Florida Governor and potential GOP presidential candidate.

"His opinion on immigration is not evolving, it's devolving," said Reid. "He keeps going backwards. I think, frankly, he's made a fool of himself."

Reid dismissed Jeb Bush's opinions, as the former Florida leader promotes his new book on immigration.

"On this issue, I don't think Jeb Bush is a Florida leader. I think [Senator] Marco Rubio is. Bush has been elected to nothing lately," Reid continued.

Monday, on the Sean Hannity Show, Bush said he's in favor of an immigration policy that allows people to come here legally to help boost America's economy. But critics say he's against a path to citizenship in his book.
