"Policy shift on 'West Wing'"

Orlando Sentinel
Tonight's issue-oriented story, about a nuclear crisis (Who tested a device in the Indian Ocean? Evidence points to the Iranians), is decidedly un-wonkish. In fact, it's a bit overheated in spots. But then, we're in February sweeps now. There's a guest star, too -- Jay Mohr, beginning a three-week stint as a right-wing cable talker who's out to get C.J.'s goat by dubbing her "Chicken of the Week" -- but he's peripheral.Not so peripheral tonight is new Vice President "Bingo Bob" Russell (Gary Cole), who's not known as much of a liberal, either. He's not known as much of anything, actually, and that's why the Republican-dominated Congress foisted him on Bartlet.
