FNC's top anchor Bill O'Reilly paid tribute to Tony Snow tonight, anchoring a live special edition of The O'Reilly Factor.

Snow and O'Reilly were more than just former colleagues — Snow was the primary guest anchor for The Radio Factor, O'Reilly's radio show.

He was also a frequent guest on O'Reilly's TV show.

O'Reilly began his show with a personal tribute to Snow. "At first we sparred on the air, but we shared a traditional point of view, and a sense of how absurd life can be," said O'Reilly. "He was one of President Bush's best hires."

O'Reilly's first guest was Secretary of State Condoleezza Rice.
