Andy Pettitte, who was excused from testifying, said in a statement to the committee that Clemens admitted to him as long as 10 years ago that he used HGH. Waxman read from affidavits by Pettitte and Pettitte's wife, Laura, supporting the accusations.

"Andy Pettitte is my friend. He was my friend before this. He will be my friend after this and again. I think Andy has misheard," Clemens said. "I think he misremembers our conversation."
