Some key figures at Roger Clemens' trial, starting Monday, on charges that the former pitcher lied when he told Congress he never used steroids and human growth hormone:
— Clemens: The famed pitcher, who won a record seven Cy Young Awards, was adamant in his denials in 2008. Prosecutors maintain he lied and broke the law when he made those denials under oath to a congressional committee.
— Brian McNamee: The strength trainer who worked out with Clemens for a decade and helped mold the Rocket into one of the most feared power pitchers, even into his 40s. McNamee maintains he injected Clemens with steroids and human growth hormone — and saved the needles, which will be evidence at trial. He'll be the prosecution's most important witness.
— Andy Pettitte: The pitcher and former teammate of Clemens — with the New York Yankees and Houston Astros — is the only person besides McNamee who says Clemens acknowledged using drugs. Clemens has said his former friend is "a very honest fellow" but insists he "misremembers" their conversation, said to have taken place in 1999 or 2000.
— Kirk Radomski: The former batboy with the New York Mets was the primary source behind the 2007 Mitchell Report examining the use of performance-enhancing drugs in Major League Baseball. Radomski has admitted providing drugs to dozens of players, and McNamee says he got the drugs for Clemens from Radomski.
— U.S. District Judge Reggie Walton: The judge is a former athlete himself. He went to college on a football scholarship and revealed in a Clemens hearing last year that he and Ken Griffey Sr. grew up playing ball together in their hometown of Donora, Pa. Walton was appointed to the federal bench in 2001 by President George W. Bush after serving on the District of Columbia Superior Court and as an adviser for crime and drug policy to President George H.W. Bush. In declaring a mistrial last year, Walton blamed prosecutors for a mistake that a "first-year law student" wouldn't make. No stranger to high-profile cases, he presided over the trial of former Vice President Dick Cheney's onetime chief of staff, Scooter Libby.
— Rusty Hardin: Clemens' lead attorney has a reputation for winning jurors over with plenty of Southern charm and colorful quips aimed to bring down opponents. His Houston firm has represented high-profile clients, including politicians and professional athletes. He successfully defended the wife of TV evangelist Joel Osteen after a flight attendant said she assaulted her when a spill on her armrest wasn't quickly cleaned up.
— Michael Attanasio: The former federal prosecutor was added to the Clemens defense team to address a conflict of interest with Hardin, who also briefly advised Pettitte just before the Mitchell Report was released. Attanasio, the son of a baseball agent, will cross-examine Pettitte.
— Assistant U.S. Attorney Steven Durham: One of two prosecutors who worked on the original case last summer, which ended in a mistrial because prosecutors showed the jury inadmissible evidence, Durham is chief of the public corruption unit at the U.S. attorney's office in Washington. He has directed a wide variety of white-collar prosecutions, including one against Riggs Bank that resulted in the largest criminal fine in the history of the Bank Secrecy Act. He also prosecuted baseball player Miguel Tejada, who pleaded guilty to a misdemeanor of misleading congressional investigators who questioned him about steroids.
— Assistant U.S. Attorney Daniel Butler: The other prosecutor from last year returning for the retrial, Butler specializes in fraud and public corruption cases and successfully prosecuted the case of "D.C. madam" Deborah Jeane Palfrey, who ran an escort service that catered to high profile clients including Sen. David Vitter, R-La.
