Polish politician Donald Tusk on Thursday tweeted a photo of him pointing a pair of fingers toward President Trump’s back, a gesture some alarmed Twitter users likened to a gun.

President Donald Trump's namesake, Donald Tusk, president of the European Council from 2014 to 2019, should watch where he points his hands the next time he's around Trump.

Nawrocki - who shared a selfie with US President Donald Trump and opposes Ukraine’s EU and NATO membership - had presented Sunday's ballot as a referendum on Tusk’s pro-European course.
