Donald Trump may soon regret using Twitter so much. Some Twitter users have banded together to request that Donald Trump unblock them on Twitter because it violates their First Amendment rights, threatening legal action if he refuses. A formal letter addressed to Trump reads Their argument is that since Trump's Twitter account is where he interacts as a member of the government, he cannot block certain people and deprive them of access just for disagreeing with him. The letter, sent by the Knight First Amendment Institute at Columbia University, was also sent to Donald McGahn, the White House Counsel, Press Secretary Sean Spicer and Dan Scavino, the Director of Social Media for the White House.
