President Trump tweeted to Polish President Andrzej Duda he will join the fight against "fake news" after reports that his wife didn't shake hands with Trump or first lady Melania Trump.

"We will fight #fakenews with you!" Trump tweeted on Saturday to Duda.

Duda tweeted on Thursday that "contrary to some surprising reports my wife did shake hands with Mrs. and Mr. Trump. Let's FIGHT FAKE NEWS"

An initial video of the encounter appeared to show Polish first lady Agata Kornhauser-Duda snubbing Trump before going to Melania, leading to a number of headlines and tweets harping on that. But a longer cut of the video showed that they did shake hands afterwards.
