President Trump met newly-elected French President Emmanuel Macron for the first time. From the pool report:

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. 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.
