USA Gymnastics failed to use Simone Biles' correct Twitter handle in their 'happy birthday' post

Simone Biles reiterated her call for an independent investigation into the Larry Nassar sex abuse scandal as she responded to a tweet from USA Gymnastics wishing her happy birthday.

Nassar, USA Gymnastics' ex-doctor, was jailed for life for abusing more than 250 athletes, including Biles and members of the Olympic teams.

"How about you amaze me and do the right thing - have an independent investigation," said the 23-year-old.

Biles is the most decorated US gymnast.

She has won 19 world titles and four Olympic gold medals.

In January, USA Gymnastics announced a plan to pay a $215m (£164m) settlement to the group of athletes abused by Nassar, who was sentenced to up to 300 years in jail in 2018.

In a 2018 interview with the BBC, Biles said she was "relieved" after speaking out about Nassar after feeling "a lot of pressure" to keep the truth to herself for so long.
