As we noted last night, NBC “Rock Center” correspondent Ted Koppel had a two-part report exploring partisan media, which included an interview with Bill O’Reilly. Koppel taped the “Rock Center” interview in O’Reilly’s studio, then, the tables were turned and O’Reilly interviewed Koppel. That interview aired a couple hours before “Rock Center” on “The O’Reilly Factor.”

O’Reilly frequently swaps interviews with other media personalities, most notable Comedy Central host Jon Stewart.
