Simone Biles is not holding back in her 23rd year. The Olympic gymnast [1] celebrated her birthday on Saturday, and amidst the festivities, she made sure to let USA Gymnastics know she's still holding it accountable for the Larry Nassar scandal.

USAG tweeted a message to Biles, and wrote, "HAPPY BIRTHDAY to the most decorated gymnast of all time, @simonebiles! We know you will only continue to amaze us and make history!" She clapped back powerfully with a tweet of her own, and said "How about you amaze me and do the right thing . . . have an independent investigation."

Biles's tweet echoes past criticism she's made of the organisation, as well as the US Olympic and Paralympic committees. She and other victims of Nassar's abuse (like Aly Raisman) have repeatedly called for an independent investigation after denouncing USAG's $215 million settlement offer. According to The Wall Street Journal, USAG originally withheld its internal investigation [4] of Nassar from Biles even though she was one of the first athletes to report his abuse.
