if it was in the hotel lobby, there should be security footage. Where is TMZ on this? And the women complained only to the NFL. I mean, Irving has a reputation from the 90s for cocaine and partying, but if he simply said something grotesque to her, I don't know if that warrants taking him off the shows.
Also, is he fired, or just off the shows? If just off the shows, he is still getting paid, and likely that is some proof that this wasn't a big enough deal to violate a "morals" clause in his contract.
