DETROIT (AP) Former Olympic gymnasts, including gold medalist Simone Biles, are among dozens of assault victims who are seeking more than $1 billion from the FBI for failing to stop sports doctor Larry Nassar , lawyers said Wednesday.

Theres no dispute that FBI agents in 2015 knew that Nassar was accused of molesting gymnasts, but they failed to act , leaving him free to continue to target young women and girls for more than a year.

It is time for the FBI to be held accountable, said Maggie Nichols, a national champion gymnast at Oklahoma in 2017-19.

Under federal law, a government agency has six months to respond to the tort claim. Lawsuits could follow, depending on the FBIs response. The Justice Department said in May that it would not pursue criminal charges against former FBI agents who failed to quickly open an investigation.

The approximately 90 claimants include Biles, Aly Raisman and McKayla Maroney, all Olympic gold medalists, according to Manly, Stewart & Finaldi, a California law firm.

If the FBI had simply done its job, Nassar would have been stopped before he ever had the chance to abuse hundreds of girls, including me, said former University of Michigan gymnast Samantha Roy.
