WASHINGTON (REUTERS) - Olympic gymnast McKayla Maroney on Wednesday told US lawmakers she feels betrayed by FBI agents, after they failed to investigate former USA Gymnastics doctor Larry Nassar, despite her telling them he had sexually abused her.

FBI director Christopher Wray told the Senate panel that the actions of the agents who botched the investigation are inexcusable, and he announced that one of the agents “no longer works for the bureau in any capacity.”
