Herman pretty much dodged the question. On one hand, it was a Texas press conference, and I can understand him not wanting to comment on another program, especially since there's an ongoing investigation. On the other hand, he still kinda makes you wonder how much he'd heard, even if he had no direct involvement.
Reminds me of when Charlie Sheen was on Two and a Half Men. Holds a knife to his wife's throat? "This is a very private matter, and we're going to let them work things out without our interference." Makes fun of the producer? "FIRED!"
