Richardson, a retired American Express executive who later became a Retrophin chairman, testified last year that during the course of their business relationship, Shkreli made comments about having sex with male colleagues and waiters in restaurants they visited.
'I was gay and had a partner, and he was starting to say certain things of a gay nature that worried me a bit.
'I thought maybe he was saying things to me because he thought I would want to hear them.
'They just felt a bit uncomfortable to me. He was saying things to me, like, "Maybe I’ll have sex with a guy in the office," or we'd be at a restaurant and there’d be a waiter and he'd say, "Maybe I should hook up with him."'
