Obama caught on audio slamming GOP

Yesterday, President Obama delivered some of his harshest criticism yet of his recent battle with Republicans to fund the government.

However, Obama may not have intended for everybody to hear him.

While listening to an audio feed from a Chicago fundraiser Thursday night, CBS News reporter Mark Knoller heard Obama speaking with donors after other reporters had left the room. That's when the president really opened up about his disdain for the recent GOP pushback:

"I said, 'You want to repeal health care? Go at it. We'll have that debate. But you're not going to be able to do that by nickel-and-diming me in the budget. You think we're stupid?'" the president said.

Obama also complained about GOP attempts to attach a bill to the resolution to fund the government that would defund women's health services provider Planned Parenthood.

"Put it in a separate bill," the president said he told House Speaker John Boehner and his staff, CBS reported. "We'll call it up. And if you think you can overturn my veto, try it. But don't try to sneak this through."

The president also made clear he is no fan of Rep. Paul Ryan (R-Wis.), the GOP's Budget Committee chairman.

"When Paul Ryan says his priority is to make sure... he's just being America's accountant and trying to be responsible-- this is the same guy that voted for two wars that were unpaid for, voted for the Bush tax cuts that were unpaid for, voted for the prescription drug bill that cost as much as my health care bill--but wasn't paid for," Obama said.
