Abbey plays doctor on “Sesame Street,” giving Elmo a checkup in an effort to soften up her public image. But the other medical news isn't so good: a conservative congresswoman (Cherry Jones) is going after the “below the belt” NIH project that Dr. Ellie Bartlet (Nina Siemaszko) is working on. Meanwhile, the judicial nomination of a law-school friend of Josh's (Michael Gaston) is being held up in committee; and C.J. has a lunch date with her old flame Ben (Brian Kerwin).
