Late Friday afternoon, FTVLive reported FIRST and EXCLUSIVELY that NBC was considering having Brian Williams step down from his perch at Nightly News. We reported that NBC was considering 3 people, including Lest Holt to replace Williams when he stepped down. 

Saturday, NBC sent out a press release saying that Williams was stepping down for "several day" and that Lester Holt would be filling in.

Williams sent a memo out saying that, "it has become painfully apparent to me that I am presently too much a part of the news, due to my actions."

Williams was scheduled to appear on CBS's Late Show with David Letterman on Thursday.

Of course, when Williams was on Letterman in 2013, he continued his lie about being shot down by an RPG in Iraq.

Sources tell FTVLive that NBC advised Williams to cancel his appearance on the late night talker and Williams did just that (despite what Howard Kurtz says).

Letterman's people pushed hard to try and get Williams to stay on the schedule, knowing that it was going to be a big ratings booster during the Feb book.
