(CNN) Multiple Olympic gymnasts have criticized USA Gymnastics' proposed $215 million settlement for survivors of Larry Nassar's sexual abuse.

On her way to a training camp for the Summer 2020 Olympics, gold medal winner Simone Biles tweeted: "Still want answers from USAG and USOPC (United States Olympic & Paralympic Committee). Wish they BOTH wanted an independent investigation as much as the survivors & I do."

And don't THEY also want to know HOW everything was allowed to happen and WHO let it happen so it NEVER HAPPENS AGAIN? Shouldn't people be held accountable? Who do I ask??? I'm torn at this point.... — Simone Biles (@Simone_Biles) February 29, 2020

Aly Raisman, another gold medal winner, tweeted that the settlement is part of a "cover up."

"The only way for anyone to know what really happened is if someone forces them to release ALL documents & data to investigate," Raisman wrote.

The problem is USAG & USOC don't want anyone to know. This is a massive cover up. The only way for anyone to know what really happened is if someone forces them to release ALL documents & data to investigate. HOW CAN WE MAKE THIS HAPPEN? https://t.co/y1kP5BX5iB — Alexandra Raisman (@Aly_Raisman) February 29, 2020

Survivors will need to vote as a group on whether to accept the $215 million settlement, or continue their lawsuit, according to a press release from USA Gymnastics. The organization said in a statement on February 22 that their proposal is open to discussion during continued negotiations with the claimants.
