The Justice Department has been asked by Congress to investigate Roger Clemens regarding whether he "committed perjury and made knowingly false statements" to a House committee. "That testimony is directly contradicted by the sworn testimony of Brian McNamee, who testified that he personally injected Mr. Clemens with anabolic steroids and human growth hormone," the congressmen wrote. "Mr. Clemens's testimony is also contradicted by the sworn deposition testimony and affidavit submitted to the committee by Andrew Pettitte, a former teammate of Mr. Clemens, whose testimony and affidavit reported that Mr. Clemens had admitted to him in 1999 or 2000 that he had taken human growth hormone."
