...In 2011, Stewart came on to O'Reilly's show to debate whether the rapper Common, who wrote a song about a woman who killed a state trooper, should have been invited to the White House.
"The president of the United States takes him into the house, thereby validating him," O'Reilly said.
Stewart points out that Bono wrote a song about Leonard Peltier, convicted of killing two FBI agents. "Guess where he was? The White House. Booya! (That's a rap word.)," Stewart replied, adding that Bob Dylan also wrote a song about a convicted killer. "Why are you drawing the line at Common? There is a selective outrage machine at Fox."
