House commitee chairman Henry Waxman, in his opening remarks, said that former Yankees Chuck Knoblauch and Andy Pettitte both confirmed Brian McNamee's accounts of their HGH use, and that both players acknowledged additional use of human growth hormone.
McNamee had said he injected Knoblauch 7 to 9 times in 2001. Knoblauch said that was the case, but that he had additional injections of HGH in 2002. Waxman said Knoblauch said he admitted to the use because he felt it important for his son's sake to tell the truth.
Pettitte admitted to using HGH on the occasion McNamee described in the Mitchell report, and in his affidavit said he also used HGH twice in 2004. "I have to tell the truth,'' Waxman quoted Pettitte as saying, "and one day I have to give an account to God.''
