Brian Williams backs out of Letterman appearance amid controversy
NEW YORK (AP) -- Embattled NBC News anchor Brian Williams is backing out of scheduled appearance on David Letterman's "Late Show" on Thursday.
That news from NBC came Sunday, a day after Williams said he was stepping away from NBC's "Nightly News" as the network looks into the anchor's admission that he had told a false story about being on helicopter hit by a grenade while reporting on the Iraq war.
Williams had spread the story of his helicopter being under attack during a previous "Late Show" interview with Letterman.
Weekend anchor Lester Holt is filling in for Williams on the "Nightly News" for at least the next several days.
