National Public Radio ceo and president Vivian Schiller has resigned -- one day after another executive was caught on a hidden-camera video bashing the Tea Party as "racist" and declaring that NPR would be better off without federal funding.

Her resignation is effective immediately.

"The board accepted her resignation with understanding, geuine regret, and great respect for her leadership of NPR these past two years," board chairman Dave Edwards said in a statement. "I recognize the magnitude of this news and that it comes on top of what has been a traumatic period for NPR and the larger public radio community."

However, NPR's media correspondent said in a tweet that Schiller was forced out.

Schiller had also been under criticism for the firing of analyist Juan Williams after he said on Fox News that he felt uncomfortable when he sees people in "Muslim garb" on airplanes.

That incident prompted conservative activist James O'Keefe to launch a secret sting operation on NPR featuring Ron Schiller, a senior NPR executive. O'Keefe was posing as a Muslim who wanted to give a $5 million gift to the news agency.

Schiller, who is not related to Vivian Schiller, described the Tea Party movement as "white, middle America, gun-toting," and added: "They're seriously racist people."

He also talked about the "anti-intellectual" component of the Republican Party.

"Liberals today might be more educated, fair and balanced than conservatives," he said.

NPR released a statement yesterday condemning the comments and noted that Schiller had left the company.

"We are appalled by the comments made by Ron Schiller in the video, which are contrary to what NPR stands for," the statement said.

UPDATE: Reaction from Sen. Jim DeMint (R-SC):

"The issue about taxpayers funding public broadcasting isn't about who gets hired or fired, it's about two simple facts: we can't afford it and they don't need it. We're facing a $1.5 trillion deficit and spending hundreds of millions on public broadcasting makes no sense today when they are raising millions from private donors and Americans already have thousands of media choices."
