Answer: In April 1974, the House Judiciary Committee subpoenaed the tapes of 42 White House conversations that dealt with the 1972 break-in at the Democratic National Committee’s headquarters at the Watergate Office Building and the subsequent attempted cover up.
At the end of that month, President Richard Nixon released edited transcripts of the White House tapes, citing executive privilege and national security as the reason he needed to withhold certain material. The Democratic-led Judiciary Committee, however, rejected the redacted transcripts, saying that they failed to comply with the subpoena.
