Top USOC executive Blackmun resigns, citing health issues

United States Olympic Committee CEO Scott Blackmun resigned on Wednesday, citing ongoing health issues resulting from prostate cancer.

USOC board member Susanne Lyons was appointed interim CEO pending a search for a permanent replacement.

Blackmun had been the CEO since 2010. He did not attend the just-concluded Winter Olympics in Pyeongchang, South Korea, while continuing medical treatment.

Blackmun's departure comes in the face of congressional inquiries into the USOC's handling of the Larry Nassar sexual-abuse case and other abuse allegations in other sports governing bodies overseen by the USOC.

"The USOC is at a critical point in its history," USOC chairman Larry Probst said in a statement. "The important work that Scott started needs to continue and will require especially vigorous attention in light of Larry Nassar's decades-long abuse of athletes affiliated with USA Gymnastics."

Nassar, the former team doctor for USA Gymnastics, has been convicted in three courts of charges that included abusing his patients. More than 200 victims, including Olympic gold medalists Aly Raisman and Jordyn Wieber, spoke at his sentencing hearing.

The USOC has been under fire for not doing more to force changes at USA Gymnastics after allegations against Nassar came to light. The Wall Street Journal reported that Blackum was informed by a former gymnastics executive in 2015 of allegations against Nassar. USA Gymnastics subsequently reported Nassar to the FBI.

The USOC is conducting a review of when Blackmun and others learned the details about abuse cases and whether they responded appropriately.
