(Reuters) - Former Senate majority leader George Mitchell, who has been probing the use of steroids in Major League Baseball, will issue his highly anticipated report Thursday, officials say.
Following are some recent drug-related scandals involving U.S. athletes.
* Barry Bonds was indicted by a federal grand jury and charged with perjury and obstruction of justice on November 15. The indictment accused Bonds of lying about his use of anabolic steroids and other performance-enhancing substances during his testimony before the grand jury that was investigating the Bay Area Laboratory Cooperative (BALCO). Bonds pleaded not guilty on December 7 to the charges.
* The International Olympic Committee ended the once-stellar Olympic career of U.S. sprinter Marion Jones on Wednesday, taking back her five Sydney 2000 Games medals after she admitted to taking drugs. She returned her medals to the U.S. Olympic Committee after telling a court in White Plains, New York, in October she had taken the banned substance known as “clear” from September 2000 to July 2001.
* U.S. cyclist Floyd Landis was banned from the sport for two years in September by the American Arbitration Association after a French laboratory found traces of synthetic testosterone in a sample provided by him during the 2006 Tour de France. Landis was the first rider to be stripped of the Tour title. He filed an appeal with the Court of Arbitration for Sport in Switzerland.
* Former U.S. Olympic sprinter Tim Montgomery was barred from competition in 2005 because of his role in a steroid scandal. In 2000, Montgomery won a gold medal as a member of the United States 4x100-meter relay team. Two years later, he set a 100-meter world record of 9.78 seconds, but the time was erased from the record books after the U.S. anti-doping agency found he had received steroids. He retired from the sport immediately afterward.
* Major League Baseball first baseman Rafael Palmeiro of the Baltimore Orioles was suspended for 10 days in August 2005 for a positive drugs test but denied he intentionally took steroids. Palmeiro finished with 569 homers for his career.
