Sorry, dude. I think it probably was the truth and the Soviets merely took advantage of it.
The reason? Clyde Tolson. Hoover and Tolson ate dinner together every night, went on vacations together, Tolson was the sole beneficiary in Hoover's will, inheriting $550,000 and Hoover's home. He also was "the loved one" who accepted the US flag from Hoover's casket during the burial service.
If that ain't queer, I have some desert property in Des Moines to sell you.
Sounds like they took you in too. Nothing at all wrong with having a close friend.
