Mark Felt (Deep Throat)

Mark Felt, known by the nickname "Deep Throat," was a key informant during the Watergate scandal, which led to the resignation of U.S. President Richard Nixon in 1974. He was an associate director of the FBI and secretly provided information to journalists investigating the scandal, helping to uncover abuses of power related to the break-in at the Democratic National Committee headquarters. Felt's identity remained a secret for many years until he was publicly revealed in 2005. His role illustrated the importance of whistleblowers in promoting transparency and accountability in government.
