Former President Donald Trump called Chairman of the Joint Chiefs of Staff Gen. Mark Milley a “f—king idiot” on Saturday during an event at Mar-a-Lago.

In video of the Trump’s remarks, he is seen talking about the Biden administration’s disastrous withdrawal and evacuation from Afghanistan that included leaving behind billions in United States military equipment. According to Trump, Milley had suggested leaving the weaponry in Afghanistan rather than removing it during the withdrawal because it would be “cheaper.”

“That’s when I realized he was a f–king idiot,” Trump said, prompting cheers and laughter from the crowd.
