Pettitte, Knoblauch Come Clean

Committee chair Henry Waxman (D-Calif) is still making his opening remarks, but we have already learned that Chuck Knoblauch admitted to injecting HGH several times. Also, Andy Pettitte admitted HGH use again on 2 occasions in 2004 while recuperating from an injury. Pettitte said no one outside his family knew of his HGH use in 2004.
