President Donald Trump shakes hands with French President Emmanuel Macron on May 25. AP Photo/Evan Vucci President Donald Trump met Emmanuel Macron, the newly inaugurated French president, for the first time on Thursday, ahead of a NATO summit in Belgium.

After pictures and an amusing pool report surfaced, the internet had a field day scrutinizing their handshake.

The pool report noted both presidents' "considerable intensity" and clenched jaws.

Their knuckles apparently went white during the tight grip, according to observers, and Trump, who is known for his intense handshakes, looked as though he wanted to disengage.
