Replacing Russert: Williams To Host MTP This Sunday; Russert's Saturday Show Replaced By Doc Programming

No permanent decisions have been made about replacing Tim Russert as moderator of "Meet The Press," or replacing Tim Russert as NBC Washington bureau chief, or replacing him on his Saturday MSNBC show, or in any other of the many roles he held within NBC News — but still, Sunday is happening in two days, and there's an empty chair that needs filling. So, for this week, at least, Russert will be replaced on "Meet The Press" by NBC News anchor and managing editor Brian Williams.

No permanent decisions have been made, and the only other announcement that has been made about the show is two guests: Senators Lindsey Graham and Joe Biden, both of whom were supposed to appear on the MTP of June 15, 2008. The senators were slated for the first half hour, with a roundtable comprised of Dan Balz and John Harwood; no word yet on whether there will be a roundtable for this show or who will participate in it. Williams will be replaced on "Nightly News" tonight and tomorrow night by Ann Curry.

But what of Russert's Saturday show? He had taped his final show — also with Harwood — prior to his death last Friday, but MSNBC did not air it last week and will not air it this week. According to MSNBC spokesperson Jeremy Gaines, the timeslots will be temporarily filled as follows: Saturday at 12 p.m. and 6 p.m. and Sunday at 2a.m. ET - documentary programming; Sunday at 11 a.m. - live news.

Details to come when they are available.
