Should The President's Tweets Create A "Public Forum"?

You might be aware that the President of the United States has a Twitter account. You might not be aware that each time he uses the account to post information about government business, the President opens a new "public forum" for assembly and debate. According to District Judge Naomi Reice Buchwald's decision in Knight First Amendment Institute v. Trump, the government controls the "interactive space" associated with the President's tweets and may not exercise that control so as to exclude other users based on the content of their speech. In other words, the District Court wrote, the First Amendment regulates the President's conduct on Twitter and prohibits him from blocking other users from replying to his political tweets. Unfortunately, this ruling could backfire, so that a decision intended to promote free speech may instead degrade or limit it.
