It later came to light that Nixon was not being truthful. A few days after the break-in, for instance, he arranged to provide hundreds of thousands of dollars in “hush money” to the burglars. Then, he and his aides hatched a plan to instruct the Central Intelligence Agency (CIA) to impede the FBI’s investigation of the crime. This was a more serious crime than the break-in: It was an abuse of presidential power and a deliberate obstruction of justice. Meanwhile, seven conspirators were indicted on charges related to the Watergate affair. At the urging of Nixon’s aides, five pleaded guilty and avoided trial; the other two were convicted in January 1973.
By that time, a growing handful of people—including Washington Post reporters Bob Woodward and Carl Bernstein, trial judge John J. Sirica and members of a Senate investigating committee—had begun to suspect that there was a larger scheme afoot. At the same time, some of the conspirators began to crack under the pressure of the cover-up. Some of Nixon’s aides, including White House counsel John Dean, testified before a grand jury about the president’s crimes; they also testified that Nixon had secretly taped every conversation that took place in the Oval Office. If prosecutors could get their hands on those tapes, they would have proof of the president’s guilt.
Nixon struggled to protect the tapes during the summer and fall of 1973. His lawyers argued that the president’s executive privilege allowed him to keep the tapes to himself, but Sirica, the Senate committee and an independent special prosecutor named Archibald Cox were all determined to obtain them. When Cox refused to stop demanding the tapes, Nixon ordered that he be fired, leading several Justice Department officials to resign in protest. (These events, which took place on October 20, 1973, are known as the Saturday Night Massacre.) Eventually, Nixon agreed to surrender some—but not all—of the tapes.
Early in 1974, the cover-up began to fall apart. On March 1, a grand jury appointed by a new special prosecutor indicted seven of Nixon’s former aides on various charges related to the Watergate affair. The jury, unsure if they could indict a sitting president, called Nixon an “unindicted co-conspirator.”
In July, the Supreme Court ordered Nixon to turn over the tapes. While the president dragged his feet, the House of Representatives voted to impeach him for obstruction of justice, abuse of power, criminal cover-up and several violations of the Constitution. Finally, on August 5, Nixon released the tapes, which provided undeniable evidence of his complicity in the Watergate crimes. In the face of certain impeachment by the Senate, the president resigned on August 8.
Six weeks after the new president Gerald Ford (1913-2006) was sworn in, he pardoned Nixon for any crimes he had committed while in office. Some of Nixon’s aides were not so lucky: They were convicted of very serious offenses and sent to federal prison. Nixon himself never admitted to any criminal wrongdoing, though he did acknowledge using poor judgment. His abuse of presidential power had a negative effect on American political life, creating an atmosphere of cynicism and distrust. While many Americans had been deeply dismayed by the outcomes of the Vietnam War, Watergate added further disappointment in a national climate already soured by the difficulties and losses of the past decade.
