Andy Lack to Return to NBC News

What is old is new again....or at least is about to be. 

Word is that NBC News will announce by the end of the week that former NBC News President Andrew Lack will return to the Peacock.

There are two rumors floating around inside 30 Rock as to what Lack's job would be?

One has him replacing NBC News President Deborah Turness.

The second rumor, which sources tell FTVLive is likely, Lack will be overseeing NBC News, MSNBC and CNBC.

That means he will replace Pat Fili-Krushel, the chairman of NBCUniversal News Group.

Sources tell FTVLive that Comcast/NBC suits started looking for a new leader after the Brian Williams scandal. Sources say that Comcast executives thought that NBC News embarrassed itself with how they handled the Williams saga and started looking for new leadership.

Insiders tell FTVLive that an announcement on Lack will likely come by the end of the week.

Stay tuned....
