The story of Deep Throat was well-known, but what lurked behind the identity of Deep Throat was not. This was not a lone whistle-blower being protected by a courageous news organization; rather, it was a news organization being used by the FBI against the president, […].

The story began on 17 June, 1972, when a group of men were caught breaking into the Watergate complex in Washington DC. They were attempting to plant listening devices in the offices of the Democratic National Committee.

Robert Smith says that two months later — on his last day at the New York Times — he had lunch with the acting director of the FBI, L Patrick Gray.

In an interview with the BBC, Mr Smith recounts how Mr Gray began divulging details of the Watergate break-in, a range of other illegal political activity, and the Nixon administration's attempts to cover it up.

[…] For Felt to have been able to guide and control the young reporters’ investigation, he needed to know a great deal of what the White House had done, going back quite far. He could not possibly have known all this simply through his personal investigations. His knowledge covered too many people, too many operations, and too much money in too many places simply to have been the product of one of his side hobbies. The only way Felt could have the knowledge he did was if the FBI had been systematically spying on the White House, on the Committee to Re-elect the President and on all of the other elements involved in Watergate. Felt was not simply feeding information to Woodward and Bernstein; he was using the intelligence product emanating from a section of the FBI to shape The Washington Post’s coverage.

This was enormously important news. The Washington Post decided not to report it. The story of Deep Throat was well-known, but what lurked behind the identity of Deep Throat was not. This was not a lone whistle-blower being protected by a courageous news organization; rather, it was a news organization being used by the FBI against the president, and a news organization that knew perfectly well that it was being used against the president. Protecting Deep Throat concealed not only an individual, but also the story of the FBI’s role in destroying Nixon.
