O'Reilly, Hannity and Greta may bolt from Fox when Roger Ailes is officially ousted: report

The chief of conservative network Fox News, Roger Ailes, is likely on his way out amid sexual harassment allegations.

Sources told CNN Money that Ailes will be leaving the network in a matter of days -- after 20 years at the network turning it into a cable channel juggernaut. He's accused of harassing employees, including the network's broadcast star, Megyn Kelly, and Fox & Friend's Gretchen Carlson.

“With internal allegations mounting, it was deemed time for him to go," an unnamed source told Deadline Hollywood.

The Wrap reports that once Ailes is gone, names that have become nearly synonymous with Fox News may soon follow.

Fox heavy hitters including Bill O'Reilly, Sean Hannity and Greta Van Susteren have contract clauses that allow them to flee the network if Ailes were to leave.

In February, The Wrap reported O'Reilly's program, The O'Reilly Factor, is a top ratings scorer for Fox.

Ailes is reported to be angry over the way the network's parent company, 21st Century Fox, which is headed by Rupert Murdoch, is treating him.

The three prime time hosts have all spoken out in defense of Ailes, who denies the allegations. Carlson has filed a lawsuit.
