"Cain’s impressive resume makes him a valuable addition to the Fox News and Fox Business lineup. As a political expert with business savvy, he brings an important voice to the nation’s debates," Bill Shine, the network's executive vice president of programming, said in a statement.
Cain is the former president and CEO of Godfather's Pizza who briefly was in the lead for the Republican presidential nomination near the end of 2011.
"I'm excited about joining the Fox family as a contributor because it is an opportunity to be one more voice for intelligent thinking in America," Cain said in a statement.
