Five-time Oscar nominee Glenn Close will guest-star on NBC's The West Wing later this month playing a potential Supreme Court justice.

"The Senate we're dealing with is a Republican majority, as it is in the real world." For more on Close's WW gig, pick up next week's issue of TV Guide magazine, on sale March 8.
