Free-Speech Group Sues Trump for Blocking Twitter Users

A free-speech group said it sued U.S. President Donald Trump for blocking Twitter users from his @realDonaldTrump account, arguing the practice violates the First Amendment of the U.S. Constitution. The lawsuit, brought by the Knight First Amendment Institute at Columbia University in New York and joined by seven individual Twitter users, claims Trump blocked a number of accounts whose owners replied to his tweets with comments that criticized, mocked or disagreed with the president.
