Olympic swimmer Ariana Kukors Smith is filing a lawsuit against USA Swimming on accusations that the organization covered up sexual abuse. Smith alleges that officials knew she was being sexually abused by coach Sean Hutchison when she was a minor. She filed the lawsuit today at the Orange County, California Supreme Court alleging that USA Swimming covered up the abuse and manipulated the background check system in Hutchison's favor. Smith says Hutchison allegedly started grooming her when she was 13 and by the time she was 16 he was sexually molesting her. Smith also says former executive director Chuck Wielgus knew that she and Hutchison were in an inappropriate relationship.
