VIDEO: Mitt Romney/Giuliani Conference About Osama bin Laden Interrupted by Protester

Republican presidential hopeful Mitt Romney ignored a heckler shouting Mitt Romney you're a racist! while he and New York Mayor Rudy Giuliani criticized Barack Obama for politicizing the killing of Osama bin Laden.

The presumptive GOP nominee had just delivered pizzas to firemen with Giuliani in Manhattan at the Engine 24/Ladder 5 fire house. It appeared the protester was a part of the Occupy movement, which was holding large May Day rallies in New York and across the country Tuesday.

I believe he certainly has a right to take credit for [the Osama bin Laden mission], said Giuliani, who was mayor of the city during the Sept. 11 attacks, but he shouldn't use it in a negative campaign.

Earlier this week the Obama campaign released an attack ad featuring former President Bill Clinton that implied Mitt Romney wouldn't have made the same call Obama did to capture or kill the al Qaeda leader in Pakistan a year ago. The ad brought back 2007 remarks Romney made about not wanting to move heaven and earth to go after bin Laden.

At the press conference, live streamed by NBC New York, Romney told reporters he wouldn't have hesitated to go after Osama bin Laden if he were in the White House.

I certainly would have taken that action myself, Romney said, speaking over an unidentified voice who screamed Mitt Romney you're a racist over and over. He made the same argument in New Hampshire on Monday, saying even Jimmy Carter would have given that order.

He also defended the 2007 comments used in the Obama ad. I think I said the same thing as the Vice President Joe Biden, which was that it was naive of the president to announce he would go into Pakistan.

Romney reportedly met with Mayor Michael Bloomberg for the first time in the Upper East Side earlier that day. According to the New York Times, the two wealthy businessmen talked about the economy, immigration, education and gun control over coffee and juice at the headquarters of the mayor's philanthropic foundation.

Giuliani endorsed his one-time 2008 presidential rival last week on Fox News. Bloomberg has not yet made an endorsement in the 2012 race, but news of his meeting with Romney sparked speculation that the former Massachusetts governor is trying to court the mayor for his favor.
