Brian Williams taking himself off air temporarily
NBC anchorman Brian Williams says he's temporarily stepping away from his nightly newscast amid questions about his credibility.
In a message sent to NBC News staff and released by NBC on Saturday, Williams says it has "become painfully apparent" to him that his actions have made him too much a part of the news.
Williams recently apologized for falsely saying on the air that he was in a helicopter hit by a rocket-propelled grenade while reporting from Iraq in 2003.
