When Fox Corp. CEO Lachlan Murdoch replied in April to the firestorm caused by his star Fox News host, Tucker Carlson, passionately invoking the “great replacement” conspiracy theory favored by white nationalists, Murdoch chose to lie. 

“A full review of the guest interview indicates that Mr. Carlson decried and rejected replacement theory,” Murdoch wrote. This was obviously and insultingly false. Carlson had explicitly endorsed its core tenets during the April 8 segment, saying that “the Democratic Party is trying to replace the current electorate, the voters now casting ballots, with new people, more obedient voters from the Third World.” White nationalists themselves knew better: They praised the Fox host for bringing their talking points to his massive audience.

His boss’ dishonest comment was a green light for Carlson to continue to promote that conspiracy theory -- and the host took it as such. Over the past two months, as Carlson became the face of Fox, “replacement” has proven a dominant theme of his program. It also spread to other Fox personalities and, increasingly, to Republican political operatives and politicians as well. Given Carlson’s sway over both his network and the GOP, that trend is likely to continue.

Here are eight examples of Carlson pushing the white nationalist “great replacement” theory in the two months since Murdoch claimed that he had actually repudiated it, most recently on Monday night. While Carlson is generally careful not to directly say that Democrats want white people replaced by nonwhite ones, his remarks -- referencing migrants from Congo, Haiti, and across the U.S.-Mexico border -- leave no one confused that that is what he is talking about.

June 7: “How did migrants get from Congo to Lewiston, Maine, and why?” Carlson asked about President Joe Biden’s immigration policy. “Well, because [Biden White House adviser] Susan Rice and ideologues like her very much want to change Maine's demographics as well as the population mix in every other state in the union.” He went on to accuse Democratic leaders of “importing huge numbers of new voters into the United States” because they “no longer believe in democracy as constituted, and they definitely don't plan to lose another election,” calling this “the most radical possible attack on the core premise of democracy.”

May 24: After the Biden administration extended temporary protected status preventing the removals of Haitian nationals residing in the U.S. who fled following a 2010 earthquake in that country, Carlson accused the Democrats of “trying to change the population of the United States, and they hate it when you say that because it's true, but that's exactly what they are doing.” During the segment, a chyron read, “Dems want to import millions of new voters.”

May 21: Responding to a guest who claimed that COVID-19 case counts were spiking in border states due to migrants spreading the virus, Carlson commented, “Public health doesn't apply when we're changing the demographic mix to favor the Democratic Party.”

April 30: Carlson accused Democrats of “an attack on our democracy” because “they only care about stacking the electorate.” He added: “They want to change who votes, so they win. They're diluting the votes of Americans, of all backgrounds, and that is an attack on democracy, period.”

April 29: Carlson described the Immigration and Nationality Act of 1965 as “an assault on democracy, a permanent one.” The law repealed the national origins quota system that “was designed to favor Western and Northern European countries and drastically limit admission of immigrants from Asia, Africa, the Middle East, and Southern and Eastern Europe,” according to the Migration Policy Institute. Carlson explained: “That law completely changed the composition of America's voter rolls, purely to benefit the Democratic Party.” (In fact, the bill passed by huge bipartisan margins, and Republican presidential nominees won five of the next six elections.)

April 21: After Rep. Ted Lieu (D-CA) responded to Rep. Scott Perry’s (R-PA) invocation of the “great replacement” theory by tweeting, “with every passing year, there will be more people who look like me in the US,” Carlson glossed Lieu’s remarks as follows: “In other words, you're being replaced, and there's nothing you can do about it. So, shut up.” 

April 15: Carlson claimed that Democrats “are changing everything, whether we like it or not,” including “a brand-new national population.” He called that a “revolution” reminiscent of how “Germany got Hitler.” 

April 12: The day after Murdoch sent his letter claiming that Carlson had actually repudiated “replacement” theory, Carlson said on his program that “the secret to the entire immigration debate” is that “demographic change is the key to the Democratic Party’s political ambitions. In order to win and maintain power, Democrats plan to change the population of the country.” He added, “All across the country, we have seen huge changes in election outcomes caused by demographic change.”

Over the same period, Carlson has also claimed that immigration “makes the country more volatile,” that migration across the U.S.-Mexico border should trigger “a real insurrection,” and that Democrats who supposedly support open borders “hate” America and are “trying to destroy it.” 

Incendiary, xenophobic rhetoric like Carlson’s can have dire consequences. Murdoch’s statement came in response to a letter from the Anti-Defamation League’s Jonathan Greenblatt, who noted that the theory Carlson espoused on April 8 is linked to “explosive hate crimes, most notably the hate-motivated mass shooting attacks in Pittsburgh, Poway and El Paso, as well as in Christchurch, New Zealand.” 

Indeed, those terrorist attacks came after Carlson and others at Fox embraced the same theory in 2018 and 2019.
