In this photo taken, Tuesday, Oct. 16, 2012, Travis Tygart, the CEO of the U.S. Anti-Doping Agency, speaks during an interview at his office in Colorado Springs, Colo. As head of the USADA, his mission is to make sports a sanctuary for finding out who's most talented and who worked the hardest, not who's the best cheater. Most recently, that mission has led him to spearhead the case that's ended lance Armstrong’s cycling and triathlon careers. (AP Photo/Ed Andrieski) less
