Elon Musk quietly ordered the removal of a Twitter suicide prevention feature, sources told Reuters.
But Twitter's head of trust and safety, Ella Irwin, said a replacement should go live next week.
The news agency reported the #ThereIsHelp feature, which appeared when users viewed certain content, had disappeared from Twitter this week.
It sought to give users credible information related to topics including HIV, mental health and suicide prevention, vaccines, and gender-based violence.
But Eirliani A Rahman, who recently left Twitter's trust and safety council, told Reuters the move was "extremely disconcerting and profoundly disturbing."
