Author Stephen King says President Trump is not right in the head after he shared an edited video early Sunday morning that appeared to show him striking Hillary Clinton in the back with a golf ball.

“Trump thinks hitting a woman with a golf ball and knocking her down is funny. Myself, I think it indicates a severely f—ed-up mind,” King tweeted.

King, who is famous for writing horror and science fiction books, has previously taken aim at Trump’s mental health, tweeting in July that “he’s an almost textbook case of personality disorder.”

{mosads}“That this guy has his finger on the nuclear trigger is worse than any horror story I ever wrote,” wrote the author of “The Shining” and “Carrie” in a separate tweet at the time. 

King has repeatedly and strongly criticized Trump in the past, regularly taking to Twitter to publicly lambast the president and other administration officials.

As a result, he claims the president has blocked him on Twitter.

The account that first tweeted the golf video has a past of sharing anti-Semitic messages, as well as tweets that attack Muslims and transgender people, BuzzFeed News noted. 

In July, Trump also came under fire for sharing an edited video that appeared to show him body slamming CNN in a wrestling match, with some saying his tweet sent the message that he condones violence against the news media.
