Final answer:
President Richard Nixon resigned due to his involvement in the Watergate scandal after evidence of his role in the cover-up emerged, leading to public disapproval and the possibility of impeachment.
Step-by-step explanation:
Why Did President Nixon Resign?
President Richard Nixon resigned from office due to his involvement in the Watergate scandal. In 1972, the break-in at the Democratic National Committee headquarters led to an investigation that uncovered illegal activities by members of Nixon's administration. Evidence surfaced, including White House tapes, that revealed Nixon had a role in the cover-up of these activities. About twenty-five of his aides were indicted, which led to a fall in public approval. Facing the prospect of being impeached and likely convicted, Nixon resigned on August 8, 1974, becoming the first U.S. president to do so.
His successor, Gerald Ford, would later pardon him, but the scandal left a permanent mark on American political history, having escalated subsequent tensions between Congress and the presidency. It was clear that the nation was troubled by a president that many believed had placed himself above the law. Nixon's inability to give clear contributions to past administrations and his attempt to delay peace talks for political gain further tainted his image.
