The lawsuit was brought by seven people he blocked on Twitter and filed by Columbia University's free speech group, the Knight First Amendment Institute, reports the BBC. When someone is blocked by a user on Twitter, that person can no longer see the tweets of the blocker. The lawsuit says that means the president is trying to "suppress dissent" in a public forum, which violates their First Amendment right to free speech. Jameel Jaffer, the executive director of the Knight First Amendment Institute, told the BBC that Trump's rampant obsession with Twitter means the social network has become "an important source of news and information about the government":
"The First Amendment applies to this digital forum in the same way it applies to town halls and open school board meetings. The White House acts unlawfully when it excludes people from this forum simply because they've disagreed with the president."
