CNNMoney: NBC and Brian Williams have come to a tentative agreement that will keep the onetime “Nightly News” anchor at the network after his six-month suspension ends in August. It will likely be announced sometime Thursday. Williams will not be returning to the “Nightly News” anchor chair; his fill-in Lester Holt will become the program’s permanent anchor. So what will Williams do? His portfolio will include a position on MSNBC, NBC’s struggling cable news channel. “He will be the face of MSNBC,” handling big breaking news stories, one of the people said on condition of anonymity.
