Award winner, was reportedly present when Armstrong asked teammate Frankie Andreu and his wife to retract a statement that they'd heard Armstrong tell a doctor had doped in an Indiana hospital room in 1996.

I felt bad for [Armstrong], I felt bad for his family and I kinda felt like the rest of America.' Crow's reps did not immediately respond to a request for comment.

If the hospital room didn't happen then just say it didn't . happen. But he won't do it because it DID happen. 'That's . not being transparent. That's not being completely honest. By saying he . won't go there is just skirting around the issue. 'This exchange has made me furious. He used to be my friend and he decimated me. I was willing to give him a . chance and this is how he responds? It just doesn't make sense.' Armstrong was close to tears at times when he spoke about the impact of his drug cheating on his family during the second part of his exclusive interview with Oprah Winfrey on Friday night.
