The White House did not immediately comment on the letter but the lawyers are prepared to go to court if the president does not heed their advice, said Alex Abdo, one of the lawyers representing the blocked users.
WASHINGTON (CNN) - President Donald Trump's approval rating is at 34%, a new Quinnipiac poll released Wednesday finds, a slight dip from the last time the university surveyed the President's popularity.
According to Fallow, if Trump does not unblock users on Twitter, he could potentially face a lawsuit from the Knight First Amendment Institute.
But among those willing to make the leap is the Knight First Amendment Institute at Columbia University.
Trump has another Twitter account, @POTUS, which he inherited from President Barack Obama and is usually reserved for official announcements or links to significant White House events.
"The president is president of the United States", Spicer said, "so they are considered official statements by the president of the United States". He rebuked them for not pursuing his original executive order banning Muslims from certain countries from entering the USA and instead throwing their legal weight behind a "watered down" version.
LawNewz.com reached out to the White House for comment, but they have not responded.
Blocking people on Twitter means they can't easily see or reply to the blocker's tweets.
Could President Trump's Twitter habit land him in hot water?
Tuesday, the institute sent a letter to the president asking him to unblock his critics on Twitter or risk facing legal action.
The letter raises interesting questions about how government social media accounts should be treated.
While many of his lackeys have tried to say Trump's tweets shouldn't be taken too seriously, who are they kidding? The Knight Institute said its arguments would apply with "equal force" to both accounts.
The tweeters' complaint is with Trump and his aides, not San Francisco-based Twitter Inc.
The president's tweets are statements of policy.
Another 48 percent say his tweets hurt GOP lawmakers up for reelection next year. In a "tweet storm" - an increasingly ubiquitous feature of the platform - Conway's husband argued Monday that the president's tweets doubling down on the nomenclature of his travel ban were imperiling the Justice Department's chances of having his controversial executive order reinstated by the Supreme Court. While a plurality of Republicans (36 percent) and Trump voters (41 percent) said Trump's tweets were a good thing, the share of those voters who said the opposite also grew.
