I lived in DC for many years. Back in the 50’s there were a lot of queers there and it was one of the first place that they came out demanding their ‘rights’. Franklin Kamaney, a fired fed, was their godfather.
Starting in the 70’s there was the start of a lot of rumors about the emergence of the kiddie porn/ child sex abuse culture. Nothing specific just rumors. The stink around the fall of Fred Richmond, the Brooklyn Kingfish in Congress, accelerated the rumor mill. By the time I finally left after 9-11 there was a pretty solid belief that child sex was a big thing in the DC corridors of power and along with lots of dope a big part of the private lives of members and staffers in Congress.
I would guess if the pizza gate was credible the permanent government moved quickly to sink it with waves of disinformation and fake news.
Just as with the Washington Starbucks murders and the death of Mary Mahoney, the child sex culture remains a DC dirty secret.
