VIDEO : NBC Removes Brian Williams From 'Nightly News'

NBC News says that Brian Williams will not return to his job as "Nightly News" anchor, but will remain anchor breaking news reports at the cable network MSNBC. NBC launched an internal investigation that turned up other instances where Williams embellished or misrepresented his experiences, frequently during appearances on talk shows. Before his swift tumble, Williams was arguably the most powerful on-air personality in television news.
