accepted a two-year suspension from track and field competition issued by USADA and announced her retirement from track and field. She broke down into tears during the press conference as she apologized for her actions, saying: "And so it is with a great amount of shame, that I stand before you and tell you that I have betrayed your trust... and you have the right to be angry with me. I have let them down. I have let my country down. And I have let myself down." USADA stated that their sanction "also requires disqualification of all her competitive results obtained after September 1, 2000, and forfeiture of all medals, results, points and prizes". On January 11, 2008, Jones was sentenced to six months in jail. She began her sentence on March 7, 2008, and was released on September 5, 2008. In the BALCO case, she had denied to federal agents her use of the steroid Tetrahydrogestrinone, known as "The Clear", or "THG", from 1999, but claimed she was given the impression she was taking a flaxseed oil supplement for two years while coach Trevor Graham supplied her with the substance. In a published letter, Jones said she had used steroids until she stopped training with Graham at the end of 2002. She said she lied when federal agents questioned her in 2003 because she panicked when they presented her with a sample of "The Clear". U.S. Olympic Committee demands return of Olympic medals Peter Ueberroth, chairman of the US Olympic Committee, reacted to the news of Jones's confession and guilty plea on perjury charges by issuing a statement calling on Jones to "immediately step forward and return the Olympic medals she won while competing in violation of the rules". Ueberroth added that her admission was "long overdue and underscores the shame and dishonor that are inherent with cheating." IAAF president Lamine Diack said in a statement: "Marion Jones will be remembered as one of the biggest frauds in sporting history." On October 8, 2007, a source confirmed that Marion Jones surrendered her five medals from the 2000 Summer Olympics. On the same day, Ueberroth said that all the relay medals should be returned, and on April 10, 2008, the IOC voted to strip Jones' relay teammates of their medals as well, although this decision would successfully be appealed by seven of Jones' teammates and overturned in 2010.
