Donald Trump has used Twitter on an almost daily basis to lash out over a variety of issues. The president has recently come under fire for blocking people and organizations he disagrees with, including legendary author Stephen King.

Trump's Twitter block

It didn't take long for Donald Trump and the mainstream media to engage in a heated war or words that eventually escalated into a full blown feud. Early on during the 2016 presidential election, Trump opted to use social media as his number one form of communication. The president would routinely clash with the press, labeling journalists as "terrible" and the "worst people" he's ever met.

The former host of "The Apprentice" didn't just reserve his Twitter outbursts for politics, however, as he would also use it to attack celebrities and entertainment outlets that were critical of his campaign. Trump made it a habit to rant about Alec Baldwin and "Saturday Night Live," while getting into more than one battle with Arnold Schwarzenegger, who went on to replace him on "The Apprentice" last season. In recent weeks, Trump has attempted to stonewall many of his critics, blocking a variety of people and organizations from viewing his tweets. On Tuesday, Vote Vets, a progressive group of military veterans, had their official Twitter account block by Trump. Just a few hours later on June 13, Stephen King was also blocked, leading to increased trolling of the president.

"The Commander in Chief can block @VoteVets, the voice of 500k military veterans and families, but we will NOT be silenced," VoteVets tweeted out early Tuesday morning. In a follow-up, Stephen King replied with similar news.

"Trump has blocked me from reading his tweets," Stephen King wrote on his Twitter feed, before sarcastically adding, "I may have to kill myself." One of the first responses to King's tweet came from entrepreneur AJ Joshi, who informed the author that he was also blocked by the president.

"Happens to the best of us," Joshi wrote.

Leading up to getting blocked, Stephen King had increased his criticism of the president and his administration. "Trump's cabinet offers a postgraduate-level course in a**-kissing," he tweeted. "If Ivanka Trump had grown up in farm country, like some of us, she'd know her father is reaping exactly what he sowed," the horror author also noted.

Twitter trouble

Earlier this week, legal counsel from the Knight First Amendment Institute at Columbia University wrote a letter to Donald Trump on behalf of two Twitter users who argue that the president blocking citizens is a violation of the First Amendment.

"Your Twitter account is a designated public forum for essentially the same reasons that open city council meetings and school board meetings are," the letter explained. As of press time, the White House has not issued a public response to the letter in question, or the backlash surrounding Trump's recent Twitter habits.
