Final answer:
G. Gordon Liddy and E. Howard Hunt was the planner and leader of the Watergate break-in, which led to the Watergate scandal and President Richard Nixon's resignation after a failed cover-up attempt.
Step-by-step explanation:
The two men who planned and were in charge of the Watergate break-in were G. Gordon Liddy and E. Howard Hunt. Liddy, who was general counsel for the Committee to Reelect the President (CREEP), and Hunt, a former CIA officer and member of the White House Plumbers, conceived and executed the plan to wiretap the Democratic National Committee's (DNC) headquarters at the Watergate complex. The break-in and subsequent cover-up eventually led to President Richard Nixon's resignation, after it was revealed that he had approved the break-in and tried to use campaign funds to silence the burglars caught at the scene.
During the Watergate scandal, it came to light that Nixon's administration was involved in many illegal activities aimed at sabotaging the Democrats. Despite Nixon's landslide victory in the 1972 presidential election, his efforts to cover up the involvement in the Watergate break-in led to the indictment and resignation of many top officials by April 1973. The Watergate scandal was exposed further by reporters Bob Woodward and Carl Bernstein and escalated with the senate investigation in the summer of 1973.
