Clemens's Lawyer Takes Aim at Brian McNamee's Credibility WASHINGTON - When Roger Clemens's perjury trial adjourned Friday, Brian McNamee, the government's star witness in the case, looked drained. His face was expressionless and pale. His body language suggested that he could use a nap. No wonder. McNamee, who testified that he injected Clemens with steroids and human growth hormone, had been on the stand for the fifth day, logging about 24 hours up there - including about 15 under harsh cross-examination by Clemens's lead lawyer, Rusty Hardin. The judge, Reggie Walton of United States District Court, has taken note of all those hours, too. He is so perturbed by the slow pace of the case that on Friday he imposed a 90-minute time limit for each side for each subsequent witness, and a two-hour limit for each side's closing argument. The trial was supposed to last four to six weeks, but it has just concluded its fifth week. If the trial does not end by June 8, Walton said, it will have to recess for one month because of scheduling conflicts. Before the government moves onto its next nine witnesses, though, McNamee - whose credibility is at the crux of the case - will have to finish his testimony. On Friday, Hardin painted him as a lying, drug-using alcoholic who turned on Clemens to save himself from prosecution. He also was a man who tried to benefit financially from Clemens's downfall, Hardin said. Hardin brought up McNamee's two D.U.I. convictions in 2002 and an incident in 2001 in which McNamee passed out drunk while with the Yankees in Seattle. Would you agree that by 2001, you were unable to control your abuse of alcohol and drugs? Hardin asked McNamee. It was at that very time, Hardin said, that McNamee said that he injected Clemens with performance-enhancing drugs. McNamee quietly answered no. Later, Hardin appeared surprised when McNamee spoke about medical waste he kept in a beer can after injecting Clemens with steroids in 2001 and said some of that evidence, including a bottle of growth hormone and a needle, came from an injection he gave another player, not Clemens. McNamee, however, had told Congressional investigators just that in 2008.
