NBC Nightly News anchor Brian Williams will moderate Meet the Press this Sunday, according to a network spokeswoman. Williams is taking over the chair while the news division's executives deliberate over choosing a long-term replacement for their late colleague, Tim Russert. Williams was a White House correspondent before he was groomed to be successor to Brokaw for

Nightly News. If Williams' assignment lasts, he won't be the first to do double duty on an evening newscast and a Sunday public affairs show. Face the Nation's Bob Schieffer continued to moderate his show while he was interim anchor of CBS Evening News. - Stephen Battaglio Related: " Did NBC News Go Overboard with Russert?
