The Supreme Court rules that public officials can block users on social networks, but in limited cases. Donald Trump was one of the elected officials who blocked users critical of his administration, when he was president.

Although this Friday's decision responds to two lawsuits against public employees in Michigan and California who censored users. The case about freedom of expression has as its background the use of these by Donald Trump. The court ruled unanimously that officials can be considered “agents of the state” when they use social media and therefore can face litigation.
