Simone Biles claps back at USA Gymnastics and its lack of accountability

Simone Biles turned 23 over the weekend, and if one of her first Twitter posts of her "[Michael] Jordan year" is any indication, she has no plans to stop demanding accountability and answers from USA Gymnastics in regards to the horrific sexual abuse charges and cases that have plagued the organization over the past several years.

USA Gymnastics, the sport's governing body in the country, celebrated Biles' birthday with a tweet on Saturday. Accompanied by a video of some of her (many) highlights, the post read: "HAPPY BIRTHDAY to the most decorated gymnast of all time, @simonebiles! We know you will only continue to amaze us and make history!"

The four-time Olympic gold medalist, and overwhelming favorite for the all-around title at the Tokyo Olympics this summer, responded shortly after by retweeting the post, and adding: "how about you amaze me and do the right thing... have an independent investigation"

Biles came forward as a survivor of abuse from former team doctor Larry Nassar, and she has been publicly critical of the organization on many occasions, including last month as she was on her way to the team training camp. She tweeted from the airport, called for an independent investigation and questioned why USAG and the USOPC didn't want answers.

Nassar, who was accused by hundreds of women, is currently serving what effectively amounts to a life sentence for sexual abuse and child pornography charges.

Biles' birthday clapback received quite a bit of attention online. Many fellow survivors were quick to add their support, including her Olympic teammate Aly Raisman.

With a combined 30 Olympic and world medals -- including five world all-around titles -- Biles is the most decorated American gymnast in history and the third-most in the world, and she almost considered by most to be the greatest of all time. However, it's her willingness to always speak up and fight for what's right that perhaps makes her even more remarkable.
