With the fallout from his sexual harassment settlements piling up and more advertisers taking flight, Bill O'Reilly told viewers of The O'Reilly Factor tonight that he's taking a vacation planned last fall and will be back in 2 weeks, but some at Fox News believe that he may not return to the air, per New York Magazine.

Why it matters: Sources tell NY Mag's Gabriel Sherman — who has led the way at every twist and turn of the O'Reilly/Roger Ailes saga — that James Murdoch, 21st Century Fox's CEO, wants to oust O'Reilly while his father Rupert is hesitant. A similar scenario played out during last year's sexual harrassment scandal involving Ailes, the network's former chairman, who eventually resigned.

Update: A Fox News spokesperson said that O'Reilly did have a pre-planned vacation and would be returning to The O'Reilly Factor on April 24.
