"There is a selective outrage machine here at Fox," Stewart says on "The O'Reilly Factor."

Jon Stewart appeared on Fox News Channel's The O'Reilly Factor on Monday to debate controversial rapper Common's invitation to perform at a White House poetry event last week.

Stewart was invited on the show after criticizing host Bill O'Reilly, who believes Common should not have been invited to the event because of his history of violent lyrics, notably directed at police officers.

Stewart argued that Common was simply "honoring someone he thinks was wrongly convicted of cop killing," while O'Reilly said, either way, the "president validated him by inviting to the White House."

Stewart added that he believes that Fox News has made this "fake controversy" into a bigger issue that it should be. He pointed out that Bob Dylan, Bruce Springsteen and Bono also have written songs about people who have killed cops.

"There is a selective outrage machine here at Fox," Stewart said.

O'Reilly isn't the only one who has been critical of the White House related to Common's appearance at the poetry event. Fox News' Sean Hannity and radio hosts Glenn Beck and Rush Limbaugh also ridiculed the White House over its decision.

And some police unions and support groups objected to the invitation.
