Simone Biles, Aly Raisman, and other gymnasts will testify before Congress about the Larry Nassar abuse scandal

• Olympic gymnasts Simone Biles, Aly Raisman, and McKayla Maroney will testify to Congress Wednesday.
• The Senate Judiciary Committee will meet on the FBI's role in the Larry Nassar sexual-abuse case.
• Biles, Maroney, and Raisman are among hundreds of women who say they were sexually abused by Nassar.

Olympians Simone Biles, Aly Raisman, and McKayla Maroney will testify before Congress at a hearing on the FBI's "dereliction of duty" in the Larry Nassar sexual abuse case, the Senate Judiciary Committee announced on Monday.

The Senate Judiciary Committee said gymnast Maggie Nichols, Department of Justice Inspector General Michael E. Horowitz, and FBI Director Christopher Wray will also testify.

In July, Horowitz released a 119-page report in which he said the FBI's Indianapolis field office "failed to respond to the Nassar allegations with the utmost seriousness and urgency that they deserved and required."

Biles, Maroney, Raisman, and Nichols are among hundreds of women who say they were sexually abused by Nassar during what he claimed were routine medical exams.

Nassar, who once served as a doctor for USA Gymnastics, was sentenced in 2018 to 175 years in prison for sexually abusing multiple girls and women under the guise of medical treatment. Even after his sentencing, Nassar said that his "treatment" was "done for a medical purpose, not for his own pleasure," according to a report from the Michigan Attorney General's Office.

Biles opened up about the abuse she faced from Nassar in 2018. This year, she said it "could have" impacted her performance in the 2020 Tokyo Olympics, in which she withdrew from several events.

"Now that I think about it, maybe in the back of my head, probably, yes, because there are certain triggers you don't even know, and I think it could have," she told "TODAY" host Hoda Kotb as the Olympics concluded.

Raisman, who testified against Nassar in his 2018, shared last year that she struggles with PTSD after the abuse.

"It's hard to put into words how much it's impacted me," Raisman said on "TODAY." "I feel like the abuse kind of took away that trust in myself, which I'm really struggling to get that back."

In July, Maroney called USA Gymnastics and the US Olympic & Paralympic Committee "abusers" that "used me and their athletes for money, but didn't care to protect us."

USAG recently put forth a plan for a $425 million settlement with Nassar's survivors. The proposal was filed with the joint approval of a Survivors' Committee that represents the hundreds of USAG abuse survivors in the organization's bankruptcy proceedings.
