Nixon made three major speeches on the Watergate scandal during 1973 and 1974. The first was on April 30, 1973, in which he announced the departure of Dean, Haldeman and Ehrlichman. A more defiant speech was delivered on August 15, 1973. Perhaps the politically most difficult speech was the one on April 29, 1974, in which Nixon released partial transcripts of the White House tapes. He ended up resigning because he knew he lost.
