CSI: Watergate

Has an amateur historian found the key to the lost 18 ½ minutes?

—By David Corn

ON JUNE 20, 1972, President Richard Nixon and his chief of staff, H.R. "Bob" Haldeman, met in Nixon's hideaway office at the Old Executive Office Building. Three days earlier, White House-connected dirty tricksters had been nabbed breaking into the Democratic National Committee's Watergate offices, and the 79-minute-long conversation—with Nixon's secret taping system running and Haldeman taking his typically meticulous notes on a tablet of yellow lined paper with a ballpoint pen—at one point turned toward the break-in and how to craft a counterattack. What exactly the two men said to one another would become one of the great political mysteries of the 20th century: Sometime during the Watergate scandal, 18 ½ minutes were suspiciously erased from the tape recording of this meeting.
