The CEO of Parler, a social media platform favored by supporters of President Trump, said it might not come back after it was taken offline following the deadly Capitol Hill siege.

CEO John Matze told Reuters on Wednesday that much about the app and website is still up in the air after businesses cut ties to the company. Amazon said it removed Parler from its cloud-hosting service because the social media platform was not effectively moderating and removing violent content. Now Matze says the company’s fate is uncertain.
