A federal court today ruled that President Donald J. Trump cannot block people from following his @realDonaldTrump account on Twitter.

The impact of the ruling, however, is not limited to the president.

Judge Naomi Reice Buchwald of the U.S. District Court for the Southern District of New York wrote, “This case requires us to consider whether a public official may, consistent with the First Amendment, ‘block’ a person from his Twitter account in response to the political views that person has expressed, and whether the analysis differs because that public official is the President of the United States. The answer to both questions is no.”
