President Trump believes he has found an international ally in his crusade against the media.

Via Twitter, he pledged Saturday to “fight the #FakeNews” with Polish President Andrzej Duda, whose right-wing party has been accused of a crackdown on a free press.

Last year, Duda signed a law putting state-owned media under government control because – according to an aide – he didn’t believe they were objective.

Trump was responding to a Thursday tweet from Duda after a widely circulated video appeared to show Polish first lady Agata Kornhauser-Duda ignoring Trump’s handshake, and shaking first lady Melania Trump’s hand instead during the first couple’s trip to Poland.

Tweeting in English, Duda wrote: “Contrary to some surprising reports my wife did shake hands with Mrs. and Mr. Trump @POTUS after a great visit. Let's FIGHT FAKE NEWS.”

A longer video showed Kornhauser-Duda shaking Melania Trump’s hand and then President Trump’s.

At Trump’s Warsaw speech, Duda loyalists shouted “Fake News!” – in English – at passing American reporters.

Trump’s dissatisfaction with the media has been a conversation topic with other world leaders.

During a visit to Washington last week, South Korean President Moon Jae-in joked to Trump that he also suffers a bit from “fake news.”

And Russian President Vladimir Putin shared a laugh with Trump before their one-on-one meeting Friday when Putin pointed to journalists and asked, “These are the ones who insulted you?”

Trump responded, “These are the ones, you’re right about that.”
