Donald Trump was unhappy with his sparsely attended military parade over the weekend and blamed it on Defense Secretary Pete Hegseth, biographer Michael Wolff revealed.

Wolff told The Daily Beast Podcast that Trump wanted a “menacing” show of force to celebrate the Army’s 250th anniversary and his 79th birthday on Saturday—but got a “festive” parade instead.

“He’s p—ed off at the soldiers,” Wolff said. “He’s accusing them of hamming it up, and by that, he seems to mean that they were having a good time, that they were waving, that they were enjoying themselves and showing a convivial face rather than a military face.”
