What the Hell Are You Doing Newt?': Giuliani Rips Gingrich's 'Alinsky' Attacks on Romney

Former New York City Mayor Rudy Giuliani on Thursday slammed Newt Gingrich's line of attack against rival Mitt Romney, saying he would expect the tactics more from Saul Alinsky than the former House Speaker.

Gingrich and fellow GOP presidential contender Rick Perry have both been attacking Romney’s venture capitalist record as the head of equity firm Bain Capital.

“I’m outraged about what [Newt] and Rick, who is a very close friend of mine, I’m shocked at what they’re doing," Giuliani said on Fox News Channel's "Fox & Friends." "I'm going to say it’s ignorant, dumb. It is building something we should be fighting in America, ignorance of the economic system.

Giuliani's appearance came after Gingrich himself was interviewed on the show and defended his tactics.

"If you get rid of venture capital, you get rid of private equity, you get rid of risk taking -- Romney was a risk-taker...that's the way we create jobs in America, that's the genius of America, that's how we move people out of poverty," Giuliani said.

But things got even more colorful when Giuliani was asked what he would say to Gingrich if he were to get him on the phone.

“What the hell are you doing, Newt? I expect this from Saul Alinsky," Giuliani said. "This is what Saul Alinsky taught Barack Obama, and the stuff you’re saying is one of the reasons we’re in the trouble we're in right now, this total ignorant populist view of the economy that was proven to be incorrect with the Soviet Union, with Chinese communism."
