The question was an example of journalistic malfeasance. It presumes that the sitting President is a racist. That is not merely dishonest, it is repugnant in it's ignorance.
Trump has disavowed white supremacy and the KKK at least five times IN public you pathetic little dunce. How many more does it take for it to sink into the tiny brains of race hustling douchebags like you?
He didn't tell a group anything and that is the lie you parrot like the gullible low IQ dupe you are. Hell, he didn't even know what the Proud Boys were, like me. But Dementia Joe sure did. If it smells like a setup, it probably is a set up.
Here is the exact exchange; it was Wallace who used the words "stand down."
Trump conflated them.
WALLACE: “Are you willing tonight to condemn white supremacists and militia groups…”
TRUMP: “Sure…”
WALLACE: “And to say that they need to stand down and not add to the violence in a number of these cities as we saw in Kenosha, and as we’ve seen in Portland”
TRUMP: “Sure, I’m prepared to do it, but I would say almost everything I see is from the left-wing not from the right-wing. I’m willing to do anything, I want to see peace…”
WALLACE: “Then do it, sir.”
BIDEN: “Do it, say it.”
TRUMP: “What do you want to call them? Give me a name.”
WALLACE: “White supremacists and right-wing militias”
BIDEN: “Proud Boys”
Trump: “Proud Boys, stand back and stand by. But I’ll tell you what, somebody’s got to do something about Antifa and the left.”
So Trump misstates what Wallace demanded, and shrill, lying, leftist loons in the PHONY media declare that Trump is telling white supremacist's to stand by. You fucking hacks are mental cases. Serious mental cases. Hey dumb fucks, the Proud Boys have denounced white supremacy and welcome ALL races. Morons.
