Washington ? Disgraced Olympic track star Marion Jones has asked President Bush to commute her six-month prison sentence for lying to federal agents about her use of performance-enhancing drugs and a check-fraud scam.

The Justice Department confirmed Monday that Jones is among hundreds of convicted felons who have applied for presidential pardons or sentence commutations, but would provide no further details. A pardon is an official act of forgiveness that removes civil liabilities stemming from a criminal conviction, while a commutation reduces or eliminates a person’s sentence.

Such applications are reviewed by the Justice Department, which makes a recommendation to the president.

It’s unclear when Jones, who won three gold and two bronze medals at the 2000 Sydney Olympics, made the request. She entered prison March 7 in Fort Worth, Texas.
