LOS ANGELES -- A staff member for Lance Armstrong's Team Radioshack went Wednesday to the grand jury room at a federal courthouse where prosecutors are presenting evidence of alleged doping in pro cycling.
Exercise physiologist Allen Lim was seen reporting to the grand jury room around 9:30 a.m. Wednesday. He was greeted by an assistant U.S. attorney overseeing the probe, which has issued subpoenas and solicited testimony about whether Armstrong and other cyclists took banned substances.
Lim also has ties to disgraced cyclist Floyd Landis, who accused him in an e-mail earlier this year of helping him cheat during his career. Lim has denied the allegations put forward by Landis, who was stripped of his 2006 Tour de France title for doping.
Grand juries meet in closed session and testimony is sealed. It was unclear how much time Lim spent before the panel, which broke for the day late Wednesday. Lim did not return a call seeking comment.
Armstrong, who won the Tour a record seven times, has repeatedly denied allegations he took performance- enhancing drugs.
Federal authorities have declined to comment on the investigation, which is being aided by Food and Drug Administration Agent Jeff Novitzky, who previously investigated steroid abuse in Major League Baseball and track and field. Novitzky also was seen in the grand jury area Wednesday.
Lim is the latest Armstrong associate to be summoned by prosecutors. Last week, longtime Armstrong friend Stephanie McIlvain appeared before jurors in an all-day session.
Her attorney later said McIlvain told the panel she had never heard Armstrong admit that he used banned substances.
McIlvain was present in the hospital room where Armstrong was being treated for cancer in 1996, when former teammate Frankie Andreu and his wife, Betsy, claim the cyclist told doctors he used performance-enhancing drugs.
Several of Armstrong's former teammates also have been contacted, and a person with knowledge of the probe told The Associated Press that former cyclist Kevin Livingston might also testify before the grand jury as early as Wednesday, though Livingston was not seen in public areas of the courthouse. Livingston was a U.S. Postal Service team member with Armstrong in 2000. The person spoke on condition of anonymity Tuesday because the investigation was ongoing.
