"They [the President and First Lady] have to select people who are almost unimpeachable," Bill O'Reilly said in defense of his criticism. "It validates him [Common]... it elevates him as a poet, or whatever."

Common Attends White House Event Despite Right-Wing Criticism

O'Reilly and other right-wing personalities including Sarah Palin and Sean Hannity targeted Common as an inappropriate White House guest due to lyrics that they believe celebrate violence. In his debate with "The Daily Show" host, O'Reilly pointed to (though not by name) Common's "A Song for Assata," the subject of which is convicted cop killer and former Black Panther member Assata Shakur.

Stewart remained calm, defending Common by saying, in regards to "A Song for Assata": "What I think he's doing is not celebrating, but honoring someone he thinks was wrongly convicted of cop killing."
