PARIS — French President Emmanuel Macron says his now famous white-knuckle handshake showdown with U.S. counterpart Donald Trump was "a moment of truth" — designed to show that he's no pushover.

Macron told a Sunday newspaper in France that "my handshake with him, it wasn't innocent. It is not the alpha and the omega of a policy but a moment of truth."

Macron added: "One must show that you won't make small concessions, even symbolic ones, but also not over-publicize things, either."

Macron's office confirmed to The Associated Press the veracity of the president's comments in Le Journal du Dimanche.

At their first meeting, ahead of a NATO summit in Brussels on Thursday, the two men locked hands for so long that knuckles started turning white. The French leader held the shake for a few seconds more. Both men's jaws seemed to clench.
