FILE - In this May 24, 2012, file photo, U.S. Olympic Committee CEO Scott Blackmun speaks at the SportAccord conference in Quebec City. Blackmun is resigning as CEO of the US Olympic Committee, citing health problems as the reason he'll depart after leading the federation for more than eight years. The 60-year-old CEO was diagnosed with prostate cancer earlier this winter, and did not attend the Pyeongchang Games. He announced his resignation Wednesday, Feb. 28, 2018, and Susanne Lyons, a member of the board, will serve as acting CEO. (Francis Vachon/The Canadian Press via AP)
