Marion Jones' lawyer has called for her ex-husband CJ Hunter to be prosecuted for "telling lies" following his claims she used drugs at the 2000 Olympics.
Jones denies ever using banned substances and her lawyer says Hunter is motivated by "revenge".
"He needs to be subjected to a polygraph investigation and prosecuted for lying to federal investigators," her attorney Joseph Burton said.
Hunter, himself banned for steroid abuse, was divorced from Jones in 2002.
Burton added: "CJ Hunter has had an axe to grind ever since Marion ended their marriage.
"Fortunately, Hunter's efforts to exact his revenge are directly contradicted by the statements made to the government investigators of Marion's former coach, who has supported everything Marion has said all along - that she never used performance enhancing drugs."
Hunter made the allegations to federal officers investigating the Balco steroids scandal sweeping American sport
Victor Conte, owner of Balco (the Bay Area Laboratory Co-Operative), faces charges of distributing drugs to athletes from several sports.
Balco's premises were raided last year after a previously undetectable steroid, THG (tetrahydrogestrinone), was
linked to the company.
Men's world 100m record holder Tim Montgomery, Jones's current partner and the father of her child, has been charged by the US Anti-Doping Agency with a doping offence as part of the investigation.
Montgomery has proclaimed his innocence and is taking his case to arbitration.
Jones failed to qualify for the sprints at this year's Olympics but is set to compete in the long jump.
The 28-year-old has never failed a drugs test.
