Pulitzer-winning journalist Glenn Greenwald is now helping launder Tucker Carlson’s white supremacist rhetoric

By Eoin Higgins

There’s no plausible way to dispute that Fox News host Tucker Carlson is spreading racist conspiracy theories, but Glenn Greenwald has been trying anyway.

Since Greenwald—a former Salon columnist, and after that a Pulitzer-winning reporter for the Guardian — departed from The Intercept in September 2020, he’s become a stalwart defender of Fox, and Carlson in particular. As Carlson has gained in viewership and impact—he’s the most widely watched cable news host in the US—his commentary and political positions have come under increased scrutiny. With that attention has come intense criticism. But he has Greenwald in his corner, who has let forth a flood of pro-Carlson arguments, primarily delivered on Twitter, his medium of choice.

Participants hold signs as people gather for

Shortly before the May 14 massacre in Buffalo that left 10 dead, the alleged shooter, 18-year-old Payton Gendron, published a 180-page manifesto online. The post explained that he targeted the Tops Market grocery store because the neighborhood was majority Black, in an act of political violence aimed at striking fear into nonwhite US residents. Gendron’s ideological outlook was highly influenced by the racist conspiracy theory known as the “Great Replacement” which holds that whites in the US are being systematically replaced by people of color in a demographic change that’s being masterminded by a cabal of elites.

That demographic-threat conspiracy theory has been laundered in prime time by none other than Carlson. Using his perch atop cable news rankings, the Fox News host has worked to spread the message of demographic threat far and wide amongst conservatives. Gendron’s manifesto doesn’t mention Carlson specifically, a point seized on by Greenwald to explain away the connections between the messaging from his favorite cable news host and the shooter. But the ideological throughline is hard to miss.

Here’s Carlson on Sept. 8, 2018:

How precisely is diversity our strength? Since you’ve made this our new national motto, please be specific as you explain it. Can you think, for example, of other institutions, such as, I don’t know, marriage or military units, in which the less people have in common the more cohesive they are? Do you get along better with your neighbors or your co-workers if you can’t understand each other or share no common values?

Here’s Gendron in his manifesto:

Why is diversity said to be our greatest strength? Does anyone even ask why? It is spoken like a mantra and repeated ad infinitum “diversity is our greatest strength, diversity is our greatest strength, diversity is our greatest strength…”. Said throughout the media, spoken by politicians, educators and celebrities. But no one ever seems to give a reason why. What gives a nation strength? And how does diversity increase that strength? What part of diversity causes this increase in strength? No one can give an answer.

Nikki McCann Ramirez, a researcher with Media Matters, noted on my podcast last week that the interconnectedness of right-wing messaging, from neo-Nazi chat boards to Fox News, makes drawing distinctions between Carlson and Gendron somewhat irrelevant.

“The shooter did not cite Tucker Carlson as an inspiration in his manifesto or as a direct source of radicalization—but what I think is important to point out here is that this man was radicalized on online forums,” Ramirez said. “Extremism researchers know that these white nationalist online forums view Carlson as an ally in spreading their messaging to the public.”


Greenwald has been a Fox News partisan for some time, in near-perfect correlation to how often he’s invited on the network. Carlson has hosted Greenwald frequently, while gaining his unswerving loyalty.

What this loyalty has meant in real terms is relentless pro-Carlson arguments from Greenwald. He has seldom criticized Carlson or Fox News—as I detailed last year—and his deference has paid off with a near-weekly slot appearing on Carlson’s primetime show. (Greenwald challenged me to come on his show and hash out our differences. When I replied with a list of dates and times I could do, he did not respond.)

Greenwald argues to critics that his appearances on Carlson’s show allow him to get a pro-privacy, anti-war message out to the network’s viewers. Yet more often than not, he’s just on Fox News to talk about Twitter, liberals, and some aspect of the culture war.

For all of Greenwald’s claims that his presence on the show might shift at least a few Fox viewers from rabid right-wing ideologues to something approaching social libertarianism, his actual appearances seem to serve mainly to support Carlson’s worldview. Greenwald doesn’t challenge Carlson’s worldview, seldom if ever criticizes the right and generally stays in his lane—legitimizing the Fox News narrative.

Thus it was unsurprising that after the Buffalo shooting, Greenwald went out of his way to make outlandish defensive claims about that worldview. One of the main points Greenwald has hammered repeatedly is the idea that Carlson is simply reacting to liberals, who are really the folks spreading conspiracy theories.

“The Democrats and their leading [strategists] for years have been arguing that immigration will change the demographic make-up of the country—by replacing conservative voters with more liberal ones—and that this will benefit them politically,” Greenwald tweeted on May 16.

In a lengthy screed on his Substack blog, Greenwald expressed outrage over the very possibility that Carlson’s critics might tie the cable news host’s rhetoric to that of the Buffalo shooter. In particular, Greenwald found the suggestion that Carlson’s worldview was fundamentally racist beyond the pale.

“His anti-immigration and ‘replacement’ argument is aimed at the idea—one that had been long mainstream on the left until about a decade ago—that large, uncontrolled immigration harms American citizens who are already here,” Greenwald said, notably without a citation or, indeed, any evidence. “There is no racial hierarchy in Carlson’s view of American citizenship and to claim that there is is nothing short of a defamatory lie.”

But the very backbone of Carlson’s replacement theory talk is, in fact, the story of racial hierarchy. Carlson doesn’t just rail at so-called “large, uncontrolled immigration”—he targets immigration as a whole from countries that he finds undesirable. It’s indistinguishable from the conspiracy theories about replacement spouted off by any number of far-right and sometimes overtly white supremacist figures.


Notably, when Greenwald is directly challenged on these points outside Twitter, he’s had difficulty defending his claims. A videotaped debate in late January with a young man named Nicholas provides a good example. Nicholas, who appears to be a teenager or very young adult, challenged Greenwald on his support for Carlson and the fact Greenwald has “never found anything negative to highlight” about the cable news host. Greenwald retorted that questions about the Fox News host were better directed at Carlson, since Greenwald didn’t watch the show. It was a strange admission from one of Carlson’s most fervent defenders.

Arguing that Carlson’s ideology is free of racism in spite of overwhelming evidence to the contrary is stunningly brazen, even for a provocateur like Greenwald. In March 2021, after Minneapolis Police Officer Derek Chauvin was found guilty of murdering George Floyd, Carlson complained that mob rule had overtaken legal justice. Finding Chauvin guilty, he argued, was essentially giving up on the rule of law because demonstrations had followed Floyd’s murder. “We must stop this current insanity,” Carlson declared. “It’s an attack on civilization.”

On Sept. 18, 2021, Carlson claimed that President Biden and the Democratic Party were attempting to “change the racial mix of the country.”

“In political terms,” Carlson told his audience, “this policy is called ‘the great replacement,’ the replacement of legacy Americans with more obedient people from far-away countries.”

Yet just months later, on Nov. 22, Greenwald tweeted that “Tucker’s view” was that the Fox News host believes “in a racially equal society.” In a debate with YouTube personality Steven Fritts released less than a week later, Greenwald said that, in his experience, Carlson’s views on race were hard to square with accusations of racism.

“I have never ever, ever, ever heard Tucker frame immigration or any other issue in the racist terms that you attributed to him,” Greenwald told Fritts. “In fact, he believes that what is racist is liberal discourse—the idea that we should judge people based on their race.”

It’s no longer enough to run interference for the Fox host—now, while expressing solidarity with Carlson, Greenwald repeats the same talking points on crime statistics and replacement theory that have been perfected in right-wing messaging.

In late March, Greenwald approvingly retweeted a cartoon by the avowedly neo-Nazi artist Stonetoss. An exhaustive New York Times report last month detailing how Carlson has mainstreamed white nationalist talking points—including 400 instances of him repeating “great replacement” language and conspiracy theories — was dismissed by Greenwald as hyperbole. “Conservatives know liberal outlets accuse everyone opposing liberalism of being racist,” Greenwald tweeted, two weeks before the Buffalo massacre. Last week, he posted FBI Black-on-Black crime statistics in an apparent effort to disprove that white nationalist violence posed a significant threat to public safety.

While Greenwald formerly defended Carlson while distancing himself from the more extreme interpretations of the Fox host’s views, today he is increasingly deploying his Twitter platform in service of spreading the white nationalist message. These vehement defenses of the most influential media purveyor of the racist “replacement” theory are destructive efforts to launder hate by a once-admirable journalist.
