In a rant on Fox News, Miller—the architect of Trump’s mass roundups and deportations of immigrants—shouted that the best way to honor Kirk’s memory was to carry out a political purge against the left, which he called a “domestic terrorism movement in this country.”

Miller provided few details on what specific left-wing figures or groups he believed were stoking this violence. He claimed the left was waging “doxxing campaigns” against right-wing figures, though he cited no specific examples.

He did, however, cite many examples of harsh, but nevertheless First Amendment-protected, speech that he considered an incitement to violence, including that “the left calls people enemies of the republic, calls them fascists, says they’re Nazis, says they’re evil,” and claimed that many people online were “celebrating” Kirk’s assassination.

“The last message that Charlie Kirk gave to me before he joined his creator in heaven,” Miller said, was, “that we have to dismantle and take on the radical left organizations in this country that are fomenting violence, and we are going to do that.”

Under President Trump’s leadership,” Miller vowed to shut down these unspecified leftist groups.

“I don’t care how,” he said. “It could be a RICO charge, a conspiracy charge, conspiracy against the United States, insurrection. But we are going to do what it takes to dismantle the organizations and the entities that are fomenting riots, that are doxxing, that are trying to inspire terrorism, that are committing acts of wanton violence.”
