Washington: US President Donald Trump has unblocked some additional Twitter users after a federal judge said in May that preventing people from following him violated individuals' constitutional rights.

US District Judge Naomi Reice Buchwald in Manhattan ruled on May 23 that comments on the President's account, and those of other government officials, were public forums and that blocking Twitter users for their views violated their right to free speech under the First Amendment of the US Constitution.

The Knight First Amendment Institute at Columbia University on August 10 sent the Justice Department a list of 41 accounts that had remained blocked from Trump's @RealDonaldTrump account. The seven users who filed suit had their accounts unblocked in June.
