Judge Naomi Reice Buchwald, of the U.S. District Court for the Southern District of New York, said President Trump’s Twitter account is a public forum and blocking people who reply to his tweets with differing opinions constitutes viewpoint discrimination, which violates the First Amendment.
The court’s ruling is a major win for the Knight First Amendment Institute at Columbia University, which brought the lawsuit on behalf of seven people who were blocked from the @realDonaldTrump account because of opinions they expressed in reply tweets.
Buchwald, who was appointed by former President Clinton, rejected Trump’s argument that the First Amendment does not apply in this case and that the president’s personal First Amendment interests supersede those of the plaintiffs.
