Conversation 081-002 of the Nixon White House tapes is a recording of a meeting between President Richard Nixon and his Chief of Staff, H. R. Haldeman, on March 21, 1973. The meeting took place in the Oval Office of the White House, and the tape was recorded by the Oval Office taping system. During the meeting, Nixon and Haldeman discuss a number of topics, including the Watergate scandal, the upcoming Senate confirmation hearings for Attorney General nominee Elliot Richardson, and the possibility of using the Internal Revenue Service (IRS) to target political opponents. The conversation is notable for its frankness and for the insights it provides into Nixon's thinking. In particular, Nixon is recorded saying that he believes he can "stonewall" the Watergate investigation and that he will not fire any of his aides who are involved in the scandal. The recording of Conversation 081-002 was one of the key pieces of evidence that led to Nixon's impeachment by the House of Representatives in 1974. Nixon resigned from office before he could be impeached by the Senate.
