President Richard Nixon took office in 1969 with the goal of ending the Vietnam War. However, the Watergate Scandal erupted in 1972 and involved a break-in at the Democratic National Committee headquarters and Nixon's subsequent cover-up. This led to Nixon's resignation in 1974, making him the first U.S. president to resign from office. His successor, Gerald Ford, granted Nixon a full pardon but saw his approval ratings drop as a result. Jimmy Carter was elected in 1976 but struggled with economic issues and crises like the Iran hostage crisis, where 52 Americans were held for over a year, weakening his presidency.
