FILE - President Richard M. Nixon points to the transcripts of the White House tapes after he announced during a nationally-televised speech that he would turn over the transcripts to House impeachment investigators, in Washington, April 29, 1974. In 1974, Richard Nixon may well have avoided criminal charges on obstruction of justice or bribery, related to the Watergate scandal, only because President Gerald Ford pardoned him just weeks after Nixon resigned the presidency.
