He's written some of the most horrific scenes in pop culture and killed off many of our favourite Game of Thrones characters, and even George RR Martin is still shocked by Trump's win.
The Song of Ice and Fire author took to his blog to comment on the outcome of the US election, calling Trump "President P***ygrabber".
He said: "There are really no words for how I feel this morning. America has spoken. I really thought we were better than this. Guess not.
"Trump was the least qualified candidate ever nominated by a major party for the presidency. Come January, he will become the worst president in American history, and a dangerously unstable player on the world stage.
"And the decimated Democrats, a minority in both House and Senate, do not have the power to hinder him.
"Over the next four years, our problems are going to get much, much worse."
He then wrapped up the post by harking back to the most famous line from his series upon which Game of Thrones is based:
"Winter is coming," he said, referencing the series' winter which heralds misery, death, and zombies from beyond the wall.
He then said: "I told you so."
