Back in June, Donald Trump blocked Stephen King on Twitter. The news hit the legendary horror writer pretty hard.Trump has blocked me from reading his tweets. I may have to kill myself.— Stephen King (@StephenKing) June 13, 2017 But now, with the coming of his movie, IT, and TV series, Mr. Mercedes, it's the perfect time for King to strike back. Time for a ban of his own."I am hereby blocking [Trump] from seeing IT or MR. MERCEDES."Donald Trump blocked me on Twitter. I am hereby blocking him from seeing IT or MR. MERCEDES. No clowns for you, Donald. Go float yourself.— Stephen King (@StephenKing) August 25, 2017 "No clowns for you, Donald. Go float yourself." Now all everyone wants is a King story starring Donald Trump. https://twitter.com/SmakTawk/status/900903043641757697 pic.twitter.com/niOnY0Dp4V— HeppCat (@the_heppcat) August 25, 2017 "I read lots of books, and let me tell you, Georgie - think he's innocent? He chased the boat, talked to the clown. Bad things, many sides."— Darren Wells (@darrenwells) August 25, 2017 But here's the thing: he's already written it, a few times, over the last few months. Granted it's been on Twitter, but that's where the greatest literature happens in the 21st century.My newest horror story: Once upon a time there was a man named Donald Trump, and he ran for president. Some people wanted him to win.— Stephen King (@StephenKing) October 21, 2016 Obama tapped Trump's phones IN PERSON! Went in wearing a Con Ed coverall. Michelle stood guard while O spliced the lines. SAD!— Stephen King (@StephenKing) March 4, 2017 Not only did Obama tap Trump's phones, he stole the strawberry ice cream out of the mess locker.— Stephen King (@StephenKing) March 4, 2017 Trump should know OBAMA NEVER LEFT THE WHITE HOUSE! He's in the closet! HE HAS SCISSORS!— Stephen King (@StephenKing) March 4, 2017 In the end, even King thinks reality is scarier than fiction.That this guy has his finger on the nuclear trigger is worse than any horror story I ever wrote.— Stephen King (@StephenKing) May 4, 2017 It's just not as entertaining. IT comes out on September 8, and Mr. Mercedes premiered on the Audience network on August 9.
