The administration is devising strategies to take measures against left-leaning groups accused by President Donald Trump and his allies of inciting political violence, according to three individuals knowledgeable about discussions concerning the federal response to the assassination of conservative activist Charlie Kirk on September 10 in Utah. One source suggested these actions might commence by the end of this month.

The White House is “trying to move quickly while not rushing,” the person said.

The anticipated actions, which are still under development, may involve scrutinizing the tax-exempt status of specific liberal organizations, as per the same source. These plans were initially reported by The Wall Street Journal.

“The White House is considering a broad range of options to tackle left-wing political violence and the network supporting and funding it,” an administration official stated. “The focus is on illegal activities,” the official emphasized, “not on political expression.”

Trump declared on “Fox & Friends” last week his intent to initiate a racketeering investigation into groups financed by billionaire George Soros, the 95-year-old financier based in New York. Trump subsequently told NBC News that Soros “should be incarcerated.”

While hosting “The Charlie Kirk Show” on Monday, Vice President JD Vance mentioned that the administration plans to examine the Soros-founded Open Society Foundations and the Ford Foundation.

“Are you aware they receive advantageous treatment? They are essentially funded by you and me, the American taxpayer,” Vance remarked. “And how do they repay us? By dismantling the foundation established by the American people over the past 250 years.”

Federal law prohibits the president and the vice president from ordering inquiries into groups’ tax status, and neither Trump nor Vance has presented evidence linking those groups to Kirk’s death. But the administration argues that it resulted from what White House deputy chief of staff Stephen Miller called “a vast domestic terror network” funded by liberal philanthropists.

“We are going to use every resource we have at the Department of Justice, Homeland Security,” Miller said in an interview with Vance on the Kirk show.

Utah County Attorney Jeffrey Gray laid out seven criminal charges — including aggravated murder — against Tyler Robinson at a news conference Tuesday and detailed the evidence in a 10-page court filing. No indication was presented Tuesday that the suspect was a member of a group. The investigation continues.

The administration official said federal authorities may explore groups alleged to have spurred riots and attacks on law enforcement officers, groups that engage in illegal doxxing campaigns — in which personal information is made public — and anyone responsible for “drop points for weapons and material.”

That work is in the early phase of planning, and it is not expected to be made operational immediately, two of the sources familiar with the matter said.

The desire to respond to Kirk’s death with policies that dismantle parts of the political left — driven by a mix of grief, fear and anger among conservatives — is palpable within Trump’s MAGA movement.

“There are a lot of groups working on what our response will look like at the state level and then the federal level,” Rachel Bovard, vice president of programs at the Conservative Partnership Institute and an ally of the Trump administration, said in a phone interview. “It’s almost the entire right. I don’t think people realize how deeply just in grief the right is.”

She described a pall hanging over conservatives and a sense of urgency.

“This isn’t like ‘how can we score political points?'” she said. “It feels existential, and it feels like there is a target on all of us right now.”

More than 100 progressive philanthropic organizations wrote an open letter Wednesday denouncing political violence, including the recent killings of Kirk and former Minnesota House Speaker Melissa Hortman, a Democrat, and pushing back against the crackdown Trump has promised.

“We reject attempts to exploit political violence to mischaracterize our good work or restrict our fundamental freedoms, like freedom of speech and the freedom to give,” wrote the groups, which include the Open Society Foundations and the Ford Foundation. “Attempts to silence speech, criminalize opposing viewpoints, and misrepresent and limit charitable giving undermine our democracy and harm all Americans.”

Some on the right are also calling for implementing more extreme measures to restrict liberal groups’ funding and activities.

Steve Bannon, host of the “War Room” podcast and a senior White House aide in Trump’s first term, said in a text message that he believes the administration should “designate ANTIFA and others ‘terrorist organizations'” to shut them down. “Designation gives you a full tool box.”

Trump said Wednesday night on Truth Social that he is designating antifa as a “MAJOR TERRORIST ORGANIZATION,” adding that he “will also be strongly recommending that those funding ANTIFA be thoroughly investigated in accordance with the highest legal standards and practices.”

Numerous federal laws criminalize domestic terrorist activity, but only foreign groups can be designated as “terrorist organizations,” a label that makes it illegal to provide support to them. The Trump administration has designated several foreign drug cartels and gangs as terrorist organizations this year in its effort to combat trafficking. But applying the designation to U.S.-based groups could require a change in federal law.

There are signs that Trump administration officials are sensitive to concerns that the response to Kirk’s death could chill free speech — concerns that have been expressed by liberals and conservatives alike.

During a speech in Michigan on Wednesday, Vance appeared to try to strike a balance.

“I want to let you know that whether you’re a Democrat or Republican, whatever your belief is, I will fight for your right to speak your mind,” he said. “We reject political violence, and we reject the crazy left-wing radicals that gunned down our friend Charlie Kirk. Let’s talk to one another and not try to shoot each other down for disagreeing.”

Utah officials are seeking the death penalty against Robinson if he is convicted. Robinson has not yet been appointed an attorney.
