U.S.A. Gymnastics has been in upheaval for several years since the revelations about Nassar, who has been accused of molesting hundreds of girls and women, including national team gymnasts, when they sought medical treatment from him.

The federation had hoped to regain some stability when it announced on Friday that Bono would be its interim president and chief executive, replacing Kerry Perry, who was forced out in September after just nine months.

The day after the announcement of Bono’s appointment, however, the Olympic champion Simone Biles posted on Twitter her frustration that Bono had covered a Nike logo after the apparel company signed a new endorsement deal with Kaepernick.

Bono had posted a photograph on Twitter of herself using a pen to black out the Nike swoosh on her golf shoes. She removed the post after Biles, the sport’s biggest star, said on Twitter: “Mouth drop. Don’t worry, it’s not like we needed a smarter usa gymnastics president or any sponsors or anything.”
