Roy Cohn
"Cohn's homosexuality was an open secret during most of his career. His public response to all questions on this subject was sometimes evasive and sometimes a flat denial; he encouraged rumors of a relationship with his long-time friend Barbara Walters, who publicly stated that she thought he was heterosexual.
Though his closeted sexuality was far from unusual at the time, it was in extreme contradiction with his public life in right-wing politics. Cohn and McCarthy targeted many government officials and cultural figures not only for communist sympathies but for homosexual tendencies, sometimes using sexual secrets as a blackmail tool to gain informants. McCarthy may not have known Cohn was gay, but it was widely believed that his aide Schine was Cohn's lover—a rumor alluded to in the Army-McCarthy hearings by Army attorney Joseph Welch: when Cohn produced a photo of Schine as evidence, Welch joked that the photo came from "a pixie ... a close relative of a fairy."
In the 1970s, no longer a national figure, Cohn frequented gay bars semi-openly, but still denied all rumors and lent his support to anti-gay political campaigns. During debates over New York City's first gay rights law, he said homosexuals should not be allowed to be schoolteachers.
In 1984, he was diagnosed with AIDS, and attempted to keep his condition secret while receiving aggressive drug treatment. He insisted to his dying day that his disease was liver cancer. His denial not only of his sexual identity but of the disease that killed him made Cohn an emblem of conservative hypocrisy to some AIDS activists, such as journalist Randy Shilts and playwright Tony Kushner. Cohn never spoke publicly about AIDS but, according to his friends, he claimed to have used his political influence to increase the government's investment in AIDS research.
He died on August 2, 1986 of complications from AIDS."
