Why did Bowman quit?

Stan Bowman has announced that he is stepping down as general manager of the US men’s Olympic ice hockey team.
He had previously left a similar post at the NHL club Chicago following an investigation into team sexual abuse.
In the spring, the ex-player of the team, whose name was not named, filed a lawsuit against Chicago, claiming that in 2010 he was sexually assaulted by former assistant head coach Brad Eldrich. Failure to thoroughly investigate the matter not only violated the then-current sexual harassment policy, but also had real consequences, including allegations of Aldrich’s sexual harassment of the intern before he was permanently suspended from the club.
The US expects to announce Bowman’s replacement in the near future. Bowman was appointed as the national team’s general manager at the end of March to prepare the national team for the 2022 Olympic Games in Beijing.

Bowman has worked at Chicago since 2001, has held the post of general manager since July 2009, under him the team won the Stanley Cup three times (2010, 2013, 2015). Stan Bowman is the son of a nine-time Stanley Cup winner as coach Scotty Bowman.
The Olympic Games will be held from 4 to 20 February in Beijing. Team USA will compete in a Group A hockey tournament, where their opponents will be Canada, Germany and China.
