Mr. Manly, the lawyer, noted that Mr. Blackmun and Mr. Penny, two officials accused of doing little or nothing to halt the abuse of athletes, have received a combined $3.4 million in severance pay.
“That’s just despicable,” Mr. Manly said.
Edward G. Williams, a lawyer and former Olympian who is co-chair of a group called the Committee to Restore Integrity to the U.S.O.P.C., said in an email that the severance payout to Mr. Blackmun was “outrageous and shocks the conscience.”
He called on Congress to act, saying the Olympic committee “cannot ever be expected to fix itself.”
A 233-page report by the law firm Ropes & Gray, commissioned by the Olympic committee and released last December, sought to determine which officials at the U.S.O.P.C. and U.S.A Gymnastics knew what, and when, about Dr. Nassar’s serial abuse. The report said the law firm’s investigators found “an ecosystem that facilitated his criminal acts.”
The report placed blame with Mr. Blackmun and Alan Ashley, the Olympic committee’s former chief of sports performance, who was fired last year, for their inaction and their attempts to keep the accusations against Dr. Nassar from becoming public.
Mr. Blackmun and Mr. Ashley learned of the accusations in July 2015, investigators found. At the time, Mr. Penny, then U.S.A. Gymnastics’ chief executive, told them that several gymnasts had accused Dr. Nassar of inappropriately touching them. Mr. Penny said he would report that abuse to the F.B.I.
Mr. Blackmun told Ropes & Gray investigators that he had called a meeting with experts and other U.S.O.C. officials after learning of the accusations. But investigators could not corroborate the story and, according to the report, Mr. Blackmun said he “was mistaken in his recollection.”
The Olympic committee did nothing to investigate whether Dr. Nassar had treated any athletes at the Olympics or any other U.S.O.P.C. event; did not examine whether the gymnastics federation was ensuring the safety of its athletes; did not report Dr. Nassar to law enforcement or check to see whether Mr. Penny had; did not bar Dr. Nassar from U.S.O.P.C. events or facilities; and did not even discuss the sexual abuse allegations with its own department that handles sexual abuse cases, the report said.
Instead, according to the report, Mr. Blackmun and Mr. Penny worked hard to “preserve their institutional interests — even as Nassar retired from the sport with his reputation intact and continued to have access to girls and young women at the college, club and high school levels.”
