Lea Michelle posted what seemed like a well-intentioned tweet, saying, “George Floyd did not deserve this. This was not an isolated incident and it must end. #BlackLivesMatter.” But her former “Glee” co-stars had quite the visceral reaction.

Quickly, other “Glee” stars started piling on, supporting Ware’s claims.
