When it comes to “Game of Thrones,” Jon Snow knows nothing. When it comes to American politics, Kit Harington prefers you think he knows nothing.

According to a profile from Esquire, the actor chooses not to “weigh in on American politics,” deferring to “experts” to take on those issues.

Looking at his quotes, it seems Harington doesn’t think politics and entertainers always mix well. The English actor says he found it “annoying” when Sean Penn decided to involve himself in the dispute over the Falkland Islands.

“I was like, ‘It has nothing to do with you, Sean Penn. Fuck off.’” said Harington.

Even so, Jon Snow still has an opinion on President Donald Trump ... er ... excuse me ... Mr. Donald Trump.

“Mr. Donald Trump — I wouldn’t call him President, I’ll call him Mister,” said Harington (to which we say, “Oh snap!”).

“I think this man at the head of your country is a con artist,” he told Esquire.

The King in the North has spoken, and there’s Snow doubt he’s not a Trump fan.

Harington’s sentiments echo those of many “Game of Thrones” cast members.

Sansa Stark herself, Sophie Turner, has spoken out against Trump and the show’s stars including Liam Cunningham regularly promote anti-Trump messages on their Twitter feeds.

In the same Esquire profile, author George R.R. Martin, whose stories inspired HBO’s “Game of Thrones,” even compared Trump to one of his most-hated characters, King Joffrey.

“I think Joffrey is now the king in America,” said Martin. “And he’s grown up just as petulant and irrational as he was when he was 13 in the books.”

Some may think Martin’s comparison is a little harsh ... you know ... for Joffrey.
