After the Sept. 10, 2025, assassination of conservative political activist Charlie Kirk, President Donald Trump claimed that radical leftist groups foment political violence in the US, and “they should be put in jail.”
“The radical left causes tremendous violence,” he said, asserting that “they seem to do it in a bigger way” than groups on the right.
Top presidential adviser Stephen Miller also weighed in after Kirk’s killing, saying that left-wing political organizations constitute “a vast domestic terror movement.”
