The bill comes after USA Gymnastics team doctor Larry Nassar was sentenced to up to 300 years in prison after more than 350 women testified he had abused them.
"We are and have been very clear that the Olympic Movement failed our athletes," U.S. Olympic & Paralympic Committee (USOPC) chair Susanne Lyons told reporters following a USOPC board meeting.
"We have also made enormous strides forward and significant changes and are continuing to do so.
"We're proud of the work we've done and we know that work is not yet completed ... and we are committed to doing it."
DeGette's bill would require Congress to appoint a 16-member commission, which would include at least eight athletes, to study how the USOPC operates and provide Congress with a list of reform recommendations.
The commission would have the power to subpoena witnesses and information from federal agencies as part of its review.
The bill is similar to one introduced in the Senate in January.
The National Olympic Committee has been pilloried since the Nassar case and come under heavy scrutiny from legislators.
A Congressional report released last December said the USOPC had prized "medals and money" over the safety of its athletes.
USOPC leaders have said that the organisation has implemented new leadership and stronger accountability measures in an effort to create a culture free from abuse.
It also said in February it would double its annual funding to $6.2 million for U.S. Center for SafeSport, the entity which investigates sexual abuse complaints raised by Olympic athletes.
