Antoine Sanfuentes, senior vice-president at NBC News, is leaving the network.
Sanfuentes tweeted Monday:
Grateful to NBC News for 24 terrific years. Looking forward to my next challenge.

The New York Post reported that he announced the news in an email to staffers. The newspaper, which obtained a copy of the memo, said that he reportedly did not agree with "NBC News chief Deborah Turness’ vision" for the organization, though he did not say in the memo why he is leaving.
He was rumored to be one of the contenders to replace former network president Steve Capus last year, but the job ultimately went to Turness. Sanfuentes served as Capus' deputy after being promoted to senior vice-president last fall. Prior to that, he was the network's Washington bureau chief.
His exit is the latest shakeup during what has already been a bumpy year for NBC News. Turness took over as president this past summer, and "Today" and "Meet the Press" have both struggled in the ratings.
