His leaks helped expose the scandal that ultimately led to the resignation of President Richard Nixon

. Felt played a key role in the FBI's handling of the Watergate investigation. After the break-in at the Democratic National Committee headquarters in the Watergate complex in June 1972, Felt, who was in a senior position at the FBI, secretly provided information to the journalists while maintaining anonymity. This was risky and costly for him personally and professionally, as he sacrificed his career and family to reveal the truth

. The story of Mark Felt and his role as Deep Throat was kept secret for over 30 years until Felt publicly revealed his identity in 2005 at age 91

. His life and actions were later depicted in the 2017 film Mark Felt: The Man Who Brought Down the White House , starring Liam Neeson as Felt, which dramatizes how he became the whistleblower behind one of the greatest political scandals in U.S. history

. In summary, Mark Felt was the man who brought down the White House by acting as the anonymous source "Deep Throat," enabling the Watergate investigation to uncover the truth about the Nixon administration's illegal activities
