At a tense political moment in the wake of conservative lightning rod Charlie Kirk’s killing, President Trump signed a presidential memorandum focusing federal law enforcement on disrupting “domestic terrorism.”

The memo appeared to focus on political violence. But during a White House signing Thursday, the president and his top advisors repeatedly hinted at a much broader campaign of suppression against the American left, referencing as problematic both the simple printing of protest signs and the prominent racial justice movement Black Lives Matter.

“We’re looking at the funders of a lot of these groups. You know, when you see the signs and they’re all beautiful signs made professionally, these aren’t your protesters that make the sign in their basement late in the evening because they really believe it. These are anarchists and agitators,” Trump said.

“Whether it be going back to the riots that started with Black Lives Matter and all the way through to the antifa riots, the attacks on ICE officers, the doxxing campaigns and now the political assassinations — these are not lone, isolated events,” said Stephen Miller, the White House deputy chief of staff. “This is part of an organized campaign of radical left terrorism.”

Neither Trump nor Miller nor the other top administration officials flanking them — including Vice President JD Vance, Atty. Gen. Pam Bondi and FBI Director Kash Patel — offered any evidence of such a widespread left-wing terror campaign, or many details about how the memo would be put into action.

Law enforcement officials have said Kirk’s alleged shooter appears to have acted alone, and data on domestic extremism more broadly — including some recently scrubbed from the Justice Department’s website — suggest right-wing extremists represent the larger threat.

Many on the right cheered Trump’s memo — just as many on the left cheered calls by Democrats for a clampdown on right-wing extremism during the Biden administration, particularly in light of the violent Jan. 6, 2021, attack on the U.S. Capitol by Trump supporters. In that incident, more than 1,500 were criminally charged, many convicted of assaulting police officers and some for sedition, before Trump pardoned them or commuted their sentences.

Many critics of the administration slammed the memo as a “chilling” threat that called to mind some of the most notorious periods of political suppression in the nation’s history — a claim the White House dismissed as wildly off base and steeped in liberal hypocrisy.

That includes the Red Scare and the often less acknowledged Lavender Scare of the Cold War and beyond, they said, when Sen. Joseph McCarthy and other federal officials cast a pall over the nation, its social justice movements and its arts scene by promising to purge from government anyone who professed a belief in certain political ideas — such as communism — or was gay or lesbian or otherwise queer.

Douglas M. Charles, a history professor at Penn State Greater Allegheny and author of “Hoover’s War on Gays: Exposing the FBI’s ‘Sex Deviates’ Program,” said Trump’s memo strongly paralleled past government efforts at political repression — including in its claim that “extremism on migration, race and gender” and “anti-Americanism, anti-capitalism, and anti-Christianity” are all causing violence in the country.

“What is this, McCarthyism redux?” Charles asked.

Melina Abdullah, a co-founder of Black Lives Matter-Los Angeles, said the Trump administration is putting “targets on the backs of organizers” like her.

Abdullah, speaking Friday from Washington, D.C., where she is attending the Congressional Black Caucus Foundation’s annual legislative conference, said Trump’s efforts to cast left-leaning advocacy groups as a threat to democracy was “the definition of gaslighting” because the president “and his entire regime are violent.”

“They are anti-Black. They are anti-people. They are anti-free speech,” Abdullah said. “What we are is indeed an organized body of people who want freedom for our people — and that is a demand for the kind of sustainable peace that only comes with justice.”

Others, including prominent California Democrats, framed Trump’s memo and other recent administration acts — including Thursday’s indictment of former FBI Director James Comey over the objections of career prosecutors — as a worrying blueprint for much wider vengeance on Trump’s behalf, which must be resisted.

“Trump is waging a crusade of retribution — abusing the federal government as a weapon of personal revenge,” Gov. Gavin Newsom posted to X. “Today it’s his enemies. Tomorrow it may be you. Speak out. Use your voice.”

California Atty. Gen. Rob Bonta noted that the memo listed various incidents of violence against Republicans while “deliberately ignoring” violence against Democrats, and said that while it is unclear what may come of the order, “the chilling effect is real and cannot be ignored.”

Bonta also sent Bondi a letter Friday expressing his “grave concern” with the Comey indictment and asking her to “reassert the long-standing independence of the U.S. Department of Justice from political interference by declining to continue these politically-motivated investigations and prosecutions.”

Sen. Alex Padilla (D-Calif.) said the Trump administration is twisting Kirk’s tragic killing “into a pretext to weaponize the federal government against opponents Trump says he ‘hates.’”

“In recent days, they’ve branded entire groups — including the Democratic Party itself — as threats, directed [the Justice Department] to go after his perceived enemies, and coerced companies to stifle any criticism of the Administration or its allies. This is pure personal grievance and retribution,” Padilla said. “If this abuse of power is normalized, no dissenting voice will be safe.”

Abigail Jackson, a White House spokesperson, said it was “the highest form of hypocrisy for Democrats to falsely claim accountability is ‘political retribution’ when Joe Biden is the one who spent years weaponizing his entire Administration against President Trump and millions of patriotic Americans.”

Jackson accused the Biden administration of censoring average Americans for their posts about COVID-19 on social media and of prosecuting “peaceful pro-life protestors,” among other things, and said the Trump administration “will continue to deliver the truth to the American people, restore integrity to our justice system, and take action to stop radical left-wing violence that is plaguing American communities.”

A month ago, Miller said, “The Democrat Party is not a political party. It is a domestic extremist organization” — a quote raising new concerns in light of Trump’s memo.

On Sept. 16, Bondi said on X that “the radical left” has for too long normalized threats and cheered on political violence, and that she would be ending that by somehow prosecuting them for “hate speech.”

Constitutional scholars — and some prominent conservative pundits — ridiculed Bondi’s claims as contrary to the 1st Amendment.

On Sept. 18, independent journalist Ken Klippenstein reported that unnamed national security officials had told him that the FBI was considering treating transgender suspects as a “subset” of a new threat category known as “Nihilistic Violent Extremists” — a concept LGBTQ+ organizations scrambled to denounce as a threat to everyone’s civil liberties.

“Everyone should be repulsed by the attempts to use the power of the federal government against their neighbors, their friends, and our families,” Human Rights Campaign President Kelley Robinson said Wednesday. “It creates a dangerous precedent that could one day be used against other Americans, progressive or conservative or anywhere in between.”

In recent days, Trump has unabashedly attacked his critics — including late-night host Jimmy Kimmel, whose show was briefly suspended. On Sept. 20, he demanded on his Truth Social platform that Bondi move to prosecute several of his most prominent political opponents, including Comey, Sen. Adam Schiff (D-Calif.) and New York Atty. Gen. Letitia James.

“We can’t delay any longer, it’s killing our reputation and credibility,” wrote Trump, the only felon to ever occupy the White House. “They impeached me twice, and indicted me (5 times!), OVER NOTHING. JUSTICE MUST BE SERVED, NOW!!!”

Comey’s indictment — on charges of lying to Congress — was reported shortly after the White House event where Trump signed the memo. Trump declined to discuss Comey at the event, and was vague about who else might be targeted under the memo. But he did say he had heard “a lot of different names,” including LinkedIn co-founder Reid Hoffman and George Soros, two prominent Democratic donors.

“If they are funding these things, they’re gonna have some problems,” Trump said, without providing any evidence of wrongdoing by either man.

The Open Society Foundations, which have disbursed billions from Soros’ fortune to an array of progressive groups globally, said in response that they “unequivocally condemn terrorism and do not fund terrorism” and that their activities “are peaceful and lawful.” Accusations suggesting otherwise were “politically motivated attacks on civil society, meant to silence speech the administration disagrees with,” the group said.

John Day, president-elect of the American College of Trial Lawyers, said his organization has not taken a position on Trump’s memo, but had grave concerns about the process by which Comey was indicted — namely, after Trump called for such legal action publicly.

“That, quite frankly, is very disturbing and concerning to us,” Day said. “This is not the way the legal system was designed to work, and it’s not the way it has worked for 250 years, and we are just very concerned that this happened at all,” Day said. “We’re praying that it is an outlier, as opposed to a predictor of what’s to come.”

James Kirchick, author of “Secret City: The Hidden History of Gay Washington,” which covers the Lavender Scare and its effects on the LGBTQ+ community in detail, said the “strongest similarity” he sees between then and now is the administration “taking the actions of an individual or a small number of people” — such as Kirk’s shooter — “and extrapolating that onto an entire class of people.”

Kirchick said language on the left labeling the president a dictator isn’t helpful in such a political moment, but that he has found some of the administration’s language more alarming — especially, in light of the new memo, Miller’s suggestion that the Democratic Party is an extremist organization.

“Does that mean the Democratic Party is going to be subject to FBI raids and extremist surveillance?” he asked.
