(CNN) Simone Biles' quest for answers about the Larry Nassar sexual abuse scandal is not stopping, not even on her birthday.

The Olympic gold medalist turned 23 on Saturday and USA Gymnastics, the sport's governing body in the United States, posted on Twitter to celebrate.

"HAPPY BIRTHDAY to the most decorated gymnast of all time, @simonebiles! We know you will only continue to amaze us and make history!" USAG tweeted.

And Biles had a very specific birthday request for them.

"how about you amaze me and do the right thing... have an independent investigation," Biles tweeted.
