Oh, is that all?

Here's a clip from a Washington Post story:

Frank, one of two openly gay members of Congress, confirmed Friday that he paid Gobie for sex, hired him with personal funds as an aide and wrote letters on congressional stationery on his behalf to Virginia probation officials, but Frank said he fired Gobie when he learned that clients were
visiting the apartment.

and
"He knew exactly what I was doing," Gobie said. "It was pretty obvious. If he had to come home early {from work}, he would call home to be sure the coast was clear . . . . He was living vicariously through me. He said it was kind of a thrill, and if he had been 20 years younger he might be doing the same thing."

Frank denies that he knew, saying he learned from his landlord and kicked Gobie out in August 1987. Gobie supports this part of Frank's story.

It seems to me he did more than engage in deviant behavior.
