Roger Clemens has bolstered his legal team, hiring a powerhouse Washington lawyer Lanny A. Breuer who represented former President Bill Clinton during his impeachment hearings as well as numerous corporations that were the subject of Congressional investigations. Rusty Hardin, Clemens?s Houston lawyer, said late Thursday that he had recruited Breuer to be his client?s ?local counsel? in Washington because of his expertise. ?We?d talked to him, and we?d just been waiting a day or two to check out conflicts,? Hardin said. ?He had no conflicts.? Clemens, who has won seven Cy Young awards but now finds his legacy in jeopardy, is facing a Congressional investigation as the result of his challenge to the Mitchell Report released last Dec. 13. The report, produced by former Senator George J. Mitchell, examined the connections between baseball and performance-enhancing drugs, and linked about 90 current and former players, including Clemens, to such drugs.
