Stars react to Alan Colmes' death at 66

Liberal political commentator Alan Colmes died Thursday after suffering a brief illness. He was 66.

Colmes rose to fame as the Fox News co-host of "Hannity and Colmes," where he battled it out with conservative pundit Sean Hannity. Respected across party lines as both funny and well-informed, Colmes began his career as a stand-up comedian before moving toward politics in the mid-1990s.

Media and political leaders like Megyn Kelly and Mike Huckabee took to Twitter after the tragic news broke. Longtime friend and co-host Hannity even posted multiple times. See their reactions in the gallery below:
