“To gangster Frank Costello and Lansky, the ability to corrupt politicians, policemen and judges was fundamental to Mafia operations. The way they found to deal with Hoover, according to several mob sources, involved his homosexuality.” This anecdote shows that Lanksy and the CIA maintained a covert relationship, which included, among other things, the sharing of blackmail material (i.e., “intelligence”).
It is also possible that Hoover was ensnared by the mob during one of Rosenstiel’s “blackmail parties,” at which Hoover sometimes found himself in attendance with prominent figures of the Mafia. Hoover was said to have worn women’s clothing at the some of the events and Meyer Lansky’s wife later said that her husband had photos of the former FBI director in drag.
