When President Nixon agreed to turn over only some of the Watergate tapes or edited transcripts to the special prosecutor, the prosecutor filed a Supreme Court case against Nixon.
Richard Nixon was the 37th President of the United States of America, and was in office from 1969 to 1974. He eventually resigned from the position due to the Watergate Scandal.
The scandal was related to abuses of power by members of the Nixon administration, as well as bugs in offices in Watergate, and other problems.
An Impeachment was on the process to happen against Nixon, so he ended up resigning.
