Democratic Sen. Chris Murphy of Connecticut issued an unsettling warning of sorts via social media on Monday, writing, “The murder of Charlie Kirk could have united Americans to confront political violence. Instead, Trump and his anti-democratic radicals look to be readying a campaign to destroy dissent.”

The senator soon after talked to Saagar Enjeti on “The Breaking Point” podcast, explaining that he’s “heartbroken” the country is not using the moment to come together and condemn political violence, adding“Instead, it looks as if President Trump and his allies are gearing up to potentially exploit this tragedy and use it as a means to do what they have been planning — to do what they have wanted to do for the entirety of their time in office — which is to try to use their control of the legal system to destroy, to obliterate the political opposition to Donald Trump.”

That might’ve sounded alarmist to some, but it wasn’t long before the White House bolstered Murphy’s concerns in dramatic fashion. The New York Times reported:

The report added that while the motive in Kirk’s slaying is still under investigation, and law enforcement officials have said that the suspected shooter acted alone, the president and several of his top allies “suggested that the suspect was part of a coordinated movement that was fomenting violence against conservatives, without presenting evidence that such a network existed.”

Trump and his team have been unsubtle in recent days about their vision. Hours after Kirk’s death, the president delivered Oval Office remarks in which the Republican not only lashed out at the left, he also vowed that his administration “will find each and every one of those who contributed to this atrocity, and to other political violence, including the organizations that fund it and support it.”

A few days later, Trump boasted to reporters“They’re already under major investigation. A lot of the people that you would traditionally say are on the left [are] already under investigation.”

This raised plenty of questions about who “they” might be and what kind of “investigations” are underway, but this was a sign of things to come — and on Monday, the White House’s campaign reached an extraordinary new level.

Deputy chief of staff Stephen Miller, for example, promised to bring the resources of the federal government to bear against what he described as “terrorist networks,” adding that he believes there are liberal organizations that constitute “a vast domestic terror movement” that the administration intends to dismantle through a variety of federal agencies and departments.

Miller delivered those comments to JD Vance — the vice president was serving as the guest host of Kirk’s podcast — who proceeded to lash out at The Nation, a progressive magazine that he accused of falsely smearing Kirk after his death, before also targeting progressive megadonor George Soros.

Soon after, Trump told reporters that he might designate antifa as a “domestic terror organization” — an apparent impossibility given that antifa is made up of loosely affiliated anti-fascist activists, and there is no organized group by that name — before adding that he was also prepared to target “other” unnamed entities. As part of the same exchange, the president said he’d already spoken to Attorney General Pam Bondi about bringing racketeering charges against “some of the people you’ve been reading about.”

For her part, Bondi told ABC News soon after that “left-wing radicals” (note the plural) were responsible for Kirk’s death, adding that “they” will be held accountable.

Miller also told reporters that the Bondi would “find out” which liberal groups are “paying for violence.”

In case this isn’t obvious, the White House could be using this opportunity to lower the temperature, reduce tensions and avoid a potentially incendiary blame game. Instead, it’s pointing to a vast conspiracy that doesn’t appear to exist, using a shooting death as a pretense to launch a multifaceted federal campaign against political opponents of the president.

The New York Times noted in March that Trump and his “allies are aggressively attacking the players and machinery that power the left,” through “a series of highly partisan official actions.” Six months later, that problem is accelerating.
