Somewhere this is already in development

Apparently J. Edgar Hoover had it in for Jack Valenti.

Previously confidential FBI files show that Hoover's deputies set out to determine whether Valenti, who had married two years earlier, maintained a relationship with a male commercial photographer. Republican Party operatives reportedly were pursuing a parallel investigation with the help of a retired FBI agent, bureau files show. No proof was ever found, but the files, obtained by The Washington Post under the federal Freedom of Information Act, provide further insight into the conduct of the FBI under Hoover, for whom damaging personal information on the powerful was a useful tool in his interactions with presidents from Franklin D. Roosevelt to Richard M. Nixon.

Johnson initially blocked the FBI from obtaining a sworn statement from Valenti or approaching the photographer, asserting that Valenti was "attracted to the women and not to the men," files show. But under FBI pressure, the president relented and approved an investigation of his close friend.

True story: I was once at a Q&A with Valenti where Joe Corey yelled at him about the level of violence in Roger Rabbit cartoon shorts.
