The FBI agents who failed to open an investigation of Larry Nassar because of the allegations against him will not be charged with a crime.
The inspector general of the agency found that two former agents probably gave inaccurate or incomplete information when investigators tried to understand what happened.
The department said that this does not reflect a view that the investigation of Nassar was handled as it should have been.
The government decided to take another look at the earlier decision to forgo charges. The deputy attorney general told Congress that she asked the head of the criminal division to review the case.
Nassar was a doctor at both Michigan State and USA Gymnastics. He is serving decades in prison for attacking female athletes.
Three gymnasts said they were sexually abused by Nassar, according to USA Gymnastics. According to the inspector general's report, the FBI did not open a formal investigation in Michigan.
The inspector general said that FBI agents in Los Angeles began a sexual tourism investigation against Nassar but didn't alert Michigan authorities.
Michigan State University police arrested Nassar in November of 2016 after an investigation.
The director of the FBI apologized to the survivors of Nassar's abuse, saying that agents had their own chance to stop him.
An FBI agent was fired and another retired. The inspector general's recommendations have been adopted by the FBI.
Lawyers for Nassar's survivors say more than 100 young women or teens were sexually abused after the FBI became aware of allegations against him. 13 people are seeking $10 million from the government.
An attorney for several of the survivors said that agents and others will not be prosecuted.
The FBI agents who knew of Nassar's abuse, did nothing, and then lied about it, have been given a pass.
