“This year, the USOC has already taken important actions to strengthen athlete safeguards and help the USOC be more effective in our mission to empower and support athletes,” new CEO Sarah Hirshland said in a statement.

“Sexual abuse, harassment and discrimination have no place in the U.S. Olympic and Paralympic community, and it’s on all of us – member organizations, institutions and individuals alike – to foster a healthy culture for competitive excellence. We will use the findings … to do everything possible to prevent something similar from happening in the future.”

The USOC board is set to meet Friday in San Francisco, where the Nassar report will top the agenda.

The report is especially tough on Blackmun, claiming the CEO knew of the sexual abuse allegations within gymnastics in 2015 but did nothing to prevent further attacks until Nassar’s actions were made public by an Indiana newspaper a year later. Blackmun also didn’t tell the Olympic Committee’s board about the allegations, investigators said.

“According to witness interviews, USOC board members remained unaware of the allegations and the potential ongoing threat to athletes until the Indianapolis Star published its account of Nassar’s abuse in September 2016,” the report said.

For a year after Blackmun learned of the Nassar allegations, the doctor still had free reign over Olympic facilities, and no steps were taken to prevent him from finding more victims, the investigation found.

“Nor did Mr. Blackmun initiate any internal review or other assessment to gather facts regarding Nassar, the athlete concerns, the scope of the alleged misconduct or Nassar’s ability to gain access to athletes at USOC-owned and operated facilities, such as the U.S. Olympic Training Center in Colorado Springs, Colorado,” the report said.

The report was issued by a law firm hired by the USOC to investigate.

“Investigators from the global law firm Ropes & Gray LLP, led by partners Joan McPhee and James P. Dowden, had complete control over the investigation, the questions asked, the documents reviewed, and the findings made,” the law firm said in a statement.

Investigators reviewed more than 1.3 million pages of documents and interviewed more than 100 witnesses.

They found that the Olympic Committee leaders were so focused on making money and winning medals that they failed to properly govern the sports it oversees. USOC controls the charters of more than four dozen Olympic sports, giving it broad power to discipline misconduct. But those powers were not brought to bear, the report found.

“As the USOC was adapting its governance model and increasing its focus on generating revenue and medals, the USOC was also adopting a service-oriented approach toward the NGBs that involved providing resources without accompanying oversight,” the report found.

The Olympic Committee said the report’s findings will lead to changes.

“The USOC will share information about additional actions it is taking as a result of these findings,” the USOC said in an email.

The report also will spur action in Congress, where lawmakers have spent much of the past year studying sexual assault in Olympic sport.
