Synopsis by Hal Erickson
Ostensibly visiting the 4077th on a standard fact-finding tour, Congressional aide R. Theodore Williamson (Lawrence Pressman) turns out to be a stooge for the McCarthyites. As such, Williamson is determined to prove that innocent Margaret (Loretta Swit) is a Commie-loving security risk. Hawkeye (Alan Alda) and B.J. (Mike Farrell) cook up a scheme to save Margaret's military career--and, incidentally, to make Williamson look a bigger jackass than he already is.
