In the wake of his admission he had not been aboard a helicopter which took RPG fire in 2003 and his subsequent non-apology apology, Brian Williams has announced he will be taking "several days" off from his position as anchor at NBC News. Weekend anchor Lester Holt will substitute for him in the interim.
I read this in one of two ways.
First, this may be Williams' face saving way of resigning without going through the motions of actually resigning. Several days turns to several months and then NBC quietly announces that Holt is the permanent anchor.
Alternately, Williams steps away with the hope that the memory of the embarrassing episode will recede in a few months at which time he would sit back down at the anchor desk.
Of course, all of this will depend on NBC News' ratings during Williams absence.
