Amidst these dark days at CBS News [see: NY Mag] there finally comes a particularly bright ray of light this morning: The network has grabbed Christopher Isham to become its Washington bureau chief, replacing the well-regarded veteran Janet Leisner, who is retiring. To most viewers this may be no big deal, but Isham was a behind-the-scenes investigative star at ABC News, from whence he comes, and probably network TV's best-known gumshoe after Brian Ross - who is well known to viewers, of course.
Isham and his I-team at ABC News have broken countless stories over the years but the one that comes immediately to mind - pointed out by the CBS press release - was the John Miller interview with Osama Bin Laden in '98. Isham started at ABC in '78, after a spell at NBC News. The appointment is effective early September.
