Obama stiffarms Limbaugh and Beck

President Barack Obama pushed back against criticism from two of his most strident opponents, conservative talk hosts Rush Limbaugh and Glenn Beck, in an interview aired Friday.

Asked by CBS' "Early Show" about the strong critiques of his time in the White House, Obama said Beck and Limbaugh and have spewed "vitriol" against him.

"When you listen to Rush Limbaugh or Glenn Beck, it's pretty apparent, but keep in mind that there have been periods in American history where this kind of vitriol comes out," Obama said. "It happens often when you've got an economy that is making people more anxious, but that's not the vast majority of Americans."

Some liberals and Democratic lawmakers have blamed Republicans ands right-wing media, such as Limbaugh, Beck and Fox News, which hosts Beck show, of fueling threats of violence to lawmakers and their families.

But Obama and other Democrats have called on Democrats to not place partisan blame for threats to lawmakers.

Obama also took a jab at former Massachusetts Gov. Mitt Romney (R) in an effort to push back against comments that his healthcare plan is "socialist."

Romney created a healthcare law in his state several years ago that Obama has compared to his own. While making the comparison on Friday, Obama slipped and called the presumed GOP presidential candidate "current Republican nominee Mitt Romney."

Romney has said he opposes the Democrats' healthcare bill.
