A handshake to remember.

President Donald Trump met with France’s newly elected president Emmanuel Macron Thursday in Brussels ahead of a NATO summit, and it was hard to miss the handshake between the two world leaders ― white knuckles and all.

“The two presidents, each wearing dark suits and blue ties (Trump’s was thick and royal blue; Macron’s was skinny and navy) sat in antique cream-upholstered arm chairs, with two American and French flags behind them,” the Washington Post’s White House reporter, Philip Rucker, described in an email. “They shook hands for an extended period of time. Each president gripped the other’s hand with considerable intensity, their knuckles turning white and their jaws clenching and faces tightening.”

Look at the intensity.

Trump reportedly tried to escape Macron’s grip twice, but to no avail. Twitter could tell the French president was ready for the interaction, which is no surprise, considering how POTUS’s handshakes have become a regular point of conversation ― mostly perplexed conversations.
