Fox News host Tucker Carlson once again began his show on Tuesday attacking the media organization that dug up years of his old radio appearances in which he regularly made racist, sexist and homophobic statements.

Carlson opened his show slamming Media Matters for America, the nonprofit research organization that monitors news companies. It had published a series of investigations on Sunday and Monday that highlighted years of Carlson’s appearances on the shock-jock radio program “The Bubba the Love Sponge Show” from 2006 to 2011. During his weekly appearances, Carlson at times called women “primitive,” challenged former President Barack Obama’s race, used homophobic terms and called Iraqis “semi-literate primitive monkeys.”

He has not apologized, but instead blamed the media for attacking him.

“Media Matters is a George Soros-funded lobbying organization, whose sole mission is to punish critics of the Democratic Party,” Carlson said Tuesday. He later attacked CNN host Brian Stelter, who had criticized Carlson’s comments, as “the house eunuch at CNN.”

Media Matters is not funded by Soros, a prominent Democratic donor.

“Tucker Carlson red face ranting about Media Matters,” the group’s president, Angelo Carusone, wrote on Twitter. “He calls for us to be shut down. Not sure how that changes that he said that stuff in the past or changes that Fox News is toxic to advertisers.”
