I know very little of the this ex-Congressman. He wasn't in Congress long. 2 years.

Why is he in the news?

Here is another strange story.

And what does "snorkelling" mean. I presume thisis a gay, term.

Eric Massa's Navy files

Ex-rep's former shipmates say unwanted advances are nothing new

According to Peter Clarke, a Navy shipmate, Massa was notorious for making unwanted advances toward subordinates. He tells the story of his friend Stuart Borsch, with whom Massa shared a hotel room while on leave during the first Gulf War. "Stuart's at the edge of the bed," Clarke says Borsch told him at the time, "and [Massa] starts massaging him. Massa said, 'You'll have to get one of my special massages.' He called them 'Massa Massages.'" Ron Moss, a Navy shipmate and Borsch's roommate, confirmed that Borsch told him this story at the time.
Clarke says that Massa's roommate, Tom Maxfield, was also assaulted. "Tom lived on upper bunk," Clarke say. "When you're on ship, you're almost exhausted 24-7. So a lot of times you sleep with your uniform on. Tom and Massa shared a stateroom together. Massa climbed up on the top of his bunk, which is hard to do--you never crawl up on somebody else's bunk. He wakes up to Massa undoing his pants trying to snorkel him." Ron Moss also confirmed hearing this story from Maxfield. Maxfield did not return calls and messages left for him--I'll update if he does.
