NBC is sending out a press release and it makes it official that former Nightly News Anchor Brian Williams will be making his debut as "MSNBC Breaking News Anchor" tomorrow. 

Williams will be anchoring coverage of Pope Francis visit and he will be getting quite a bit of help from some of his old colleagues at NBC News.  In fact the coverage will use only NBC News regulars while BriWi is on the air.

No MSNBC people (i.e. Maddow, Mathews) are involved in the coverage. 

Here is the release from NBC:

MSNBC will present live special coverage of Pope Francis’ visit to the United States and Cuba beginning on Tuesday, September 22 anchored by Brian Williams.  Williams will be joined by Kate Snow, Chuck Todd, Steve Kornacki, Andrea Mitchell, Kasie Hunt and other NBC News journalists and contributors to give historical perspective and political context to this historic Papal visit.  Chris Matthews will also anchor live from Philadelphia beginning on Friday, September 25 ahead of the Pope’s masses and events which will take place throughout the weekend.
