Former White House press secretary and Fox News anchor, Tony Snow, has joined CNN as a commentator, starting today. Snow previously spent time with CNN as a substitute co-host of Crossfire.

"I'm delighted to be able to join CNN during the most exciting and unpredictable political year in memory," Snow said in the CNN release.

Snow was recently named the permanent guest host of the Radio Factor. There is no word whether that role will continue.
