There were apparently "requests" made under both administrations. I'm open to whether one administration, both administrations, or neither administration, crossed the line. It's possible that the requests under Biden were more frequent and/or more forceful. It's also possible that their requests related to different sorts of issues. I didn't watch the hearing(s), but Elon only seems to care about the requests under Biden. Whether that's a result of how partisan and conspiracy-minded he's become or something else (such as when he acquired the company), I don't know. But I'm definitely not taking his word for it when he tweets the kind of goofy, trolling nonsense that he does. Twitter Kept Entire 'Database' of Republican Requests to Censor Posts
