Reveal

Although he called Nixon’s actions "treason," LBJ decided not to reveal the sabotage, because of how he knew about it - the FBI had tapped the South Vietnamese ambassador’s phones and LBJ had transcripts of the ambassador’s talks with Nixon’s intermediary, Anna Chenault, and revealing Nixon’s involvement in the scheme would have meant revealing the illegal wiretaps. Oops. Johnson’s administration did pass the information on to the Humphrey campaign, which chose not to use it either, since their polling suggested that they would win. Oops, again.

Ah, Democrats...
