National Public Radio president and CEO Vivian Schiller resigned Wednesday after comments by a fellow executive angered conservatives and renewed calls to end its federal funding.

Schiller's resignation is effective immediately. An NPR media correspondent tweeted that Schiller was forced out by the board.

A group of tea partiers want to cut federal funding to NPR citing a recent undercover video showing an NPR top fundraiser calling the group "racist."

In the undercover video released Tuesday by conservative activist James O'Keefe, another man poses as a Muslim educator and offers NPR executive Ron Schiller a $5 million donation.

Ron Schiller is shown in the video saying NPR doesn't need government funding. He also criticized Christian conservatives, saying the Republican Party had been taken over by "white, middle America, gun-toting racists."

"The current Republican Party, particularly the Tea Party, is fanatically involved in people's personal lives and very fundamentally Christian," Schiller said.  "And I wouldn't even call it Christian. It's this weird evangelical kind of move."

"Mr. Schiller himself candidly admits in the video that NPR doesn't need federal funding, and welcomes the opportunity to slant their reporting without the oversight of the taxpayer," Mark Meckler, national coordinator for Tea Party Patriots responded Tuesday.

In a statement, NPR said it was appalled by Schiller's comments.

Schiller has since left NPR for another job.

The Tea Party Patriots are urging supporters to help "pass legislation that would de-fund the clearly biased news organization that is out of touch with Americans across the country."
