Donald Trump should be allowed to block people from his Twitter feed because it is not an official government account, the president’s lawyers have re-argued in a legal appeal.

The lawyers are asking that a decision by a subset of the Second Circuit be reviewed by the entire court. Their core argument remains that the @realDonaldTrump account should not subject to the First Amendment – where he is not allowed to block access as it is a “public forum” – because it is a personal account and he is entitled to do with as he pleases.
