“I’d like to see it [the nation] heal,” the president told NBC News. “But we’re dealing with a radical left group of lunatics, and they don’t play fair and they never did.”

On Sunday, Trump announced that he would be attending the funeral of Charlie Kirk. Hhe also warned that left-leaning groups could be investigated after the killing, but didn’t specify which or how.

“If you look at the problem, the problem is on the left. It’s not on the right, like some people like to share the right, the problem we have is on the left,” Trump said. “And when you look at the agitator, you look at the scum that speaks so badly of our country, the American flag burnings all over the place, that’s the left. That’s not the right.”

While Trump has been very open with his views after the killing of Charlie Kirk, his statements haven’t solely been met with appreciation.
