Simone Biles was in tears as she spoke about the anger and disappointment she feels about the handling of the Larry Nassar sexual abuse scandal, only two days before attempting to win her sixth US national title.

It is just over 18 months since the Olympic gymnastics champion revealed she was among the hundreds of athletes abused by Nassar, the USA Gymnastics’ disgraced sports doctor, who abused dozens of athletes in his care.

While Nassar is now behind bars for the rest of his life and USA Gymnastics has undergone a massive overhaul in leadership, Biles said the organization had 'failed' its athletes.
