Horror author Stephen King has revealed President Donald Trump has blocked him on Twitter.

The It writer joked he “may have to kill myself” after his repeated criticism of the US leader led to him taking action on the social media site.

Stephen regularly hits out at President Trump on Twitter. On Tuesday, hours before he revealed he had been blocked, he wrote: “Trump’s cabinet offers a postgraduate-level course in ass-kissing.”

In February he said he “screws up” America’s relationship with Australia and called the Republican “an impulsive, bad-tempered idiot.”

Last week he posted: “Our idiotic president seems to have confused what’s “politically correct” with what is “unconstitutional”.”

Lawyers for two Twitter users last week sent the White House a letter demanding they be un-blocked from the @realDonaldTrump account.
