[R]ead Lawrence H. Silberman's column in OpinionJournal:
Only a few weeks before the 1964 election, a powerful presidential assistant, Walter Jenkins, was arrested in a men's room in Washington. Evidently, the president [Lyndon Johnson] was concerned that Barry Goldwater would use that against him in the election. Another assistant, Bill Moyers, was tasked to direct Hoover to do an investigation of Goldwater's staff to find similar evidence of homosexual activity. Mr. Moyers' memo to the FBI was in one of the files.
Yes, that Bill Moyers.
