Here's some "TV News" scoop from the new issue of TV Guide magazine (on sale now): Mary McCormack, last seen in USA Network's druggie drama Traffic, is on the move. Starting April 21, Howard Stern's big-screen wife will appear in at least four episodes of The West Wing as the Prez's Deputy National Security Advisor. Which puts shock jock Stern one degree of separation away from the red button. These are scary times, folks. Scary times indeed.
