Twitter on Friday removed the accounts of Michael Flynn, Sidney Powell and other high-profile supporters of President Donald Trump who promoted the QAnon conspiracy theory. The permanent bans are among the highest profile that the company has instituted as part of its efforts to crack down on misinformation and calls for violence. Flynn and Powell both met with Trump at the White House in recent weeks as part of efforts to overturn the presidential election results. They are also high-profile figures in the QAnon community, and Flynn even took an “oath” to the conspiracy theory last year.
