Follow up on Tom Brokow from the Associated Press:

South Dakotan Tom Brokaw, former NBC news anchor says he's doing OK, after being taken to a Charlotte, N.C., hospital this morning following an appearance on MSNBC. The network says Brokaw felt "light-headed," and was taken to the hospital out of an "abundance of caution." The NBC News special correspondent later tweeted, "All is well." He said he had "mistakenly" taken a half-dose of Ambien, and, in his words, "made less sense than usual."
