Nixon: "One Year of Watergate Is Enough."
Amid the Watergate scandal, President Richard Nixon wanted nothing more than to shift the public’s attention to other issues. His 1974 address focused mostly on the ongoing --and crippling -- energy crisis, but with evidence mounting that he may have covered up a 1972 break-in at Democratic National Committee headquarters, he couldn't avoid the topic altogether. After a long pause for applause near the end of his speech, Nixon brought it up: "I believe the time has come to bring that investigation and the other investigations of this matter to an end. One year of Watergate is enough." In reality, the investigation would continue for nearly seven more months, culminating in his resignation. Just two weeks after Nixon spoke to the joint session of Congress, the House voted, 410-4, to give the Judiciary Committee authority to investigate impeachment charges against the president.
