On May 23, one of President Donald Trump’s Twitter habits — his practice of blocking critics on the service, preventing them from engaging with his account — was declared unconstitutional by a federal judge in Manhattan.

Judge Naomi Reice Buchwald, addressing a novel issue about how the Constitution applies to social media platforms and public officials, found that the president’s Twitter feed is a public forum. As a result, she ruled that when Mr. Trump or an aide blocked seven plaintiffs from viewing and replying to his posts, he violated the First Amendment.
