O'Reilly: 'Trump Insurgency Is Threat to Liberal America, & the Media Doesn't Like It'

Rubio Defends His Repetition of Talking Point During Debate: 'It's What I Believe'

Jeb Bush sat down with Sean Hannity tonight hours before the New Hampshire primary.

A recent poll of likely voters showed Bush in second place behind Donald Trump.

Bush said of his rebound: "I'd been written off. I've seen obituaries written about myself ... I'm still alive."

Hannity asked the former Florida governor about Marco Rubio's much-criticized debate performance and infighting between Republican candidates.

"It's one of those rare moments where a narrative had been built up, and then it was validated by the candidate himself," Bush said about Rubio. "Fair or unfair, that's just the way it is."

He continued: "Marco complains that my super PAC's attacking him. Well, his super PAC's attacking me. It's just the nature of the beast. And frankly, we need to all toughen up, whoever's going to be the nominee. Can you imagine what the Clinton hit machine looks like? They have nothing to offer other than tearing down the Republican."
