"Shortly after criticizing leaders of the U.S. Olympic Committee in a local television interview earlier this month, rapid-fire pistol shooter Keith Sanderson was booted from the men’s national team and kicked out of the U.S. Olympic Training Center in Colorado Springs, Colo. USA Shooting, the organization approved by USOC to manage the sport, accused the three-time Olympian of multiple violations of its code of conduct. Mr. Sanderson, who was elected by fellow elite athletes to represent them on the Athletes’ Advisory Council, claims he’s being punished for his outspokenness."
"I believe him, because something similar happened to me. I was removed in 2016 from my role as an elected athlete representative at USA Triathlon after I lobbied congressional staff for reforms to the USOC. If this is how whistle-blowers are treated, is it any wonder Larry Nassar’s reign of sexual abuse at USA Gymnastics lasted as long as it did"
"A growing chorus of past Olympians is calling for reform. Only Congress can fix the problem."
