Steve Bannon enthusiastically joined the MAGA immigration civil war on Friday, calling Elon Musk a “toddler” and telling the owner of X to “bring it with him.”

As Musk doubled down on his support for H1-B work visas and his criticism of American workers, Bannon posted on the social media platform Gettr: “Please notify ‘Child Protective Services’ – I need to do a ‘health check’ on this toddler. “”

The former Trump adviser and War Room podcast host wrote the post in response to Musk telling a critic of his stance on immigration to “go fuck himself in the face.”

“The reason I am in America along with so many critical people who built SpaceX, Tesla and hundreds of other companies that have made America strong is because of H1B,” Musk wrote.

“Take a big step back and fuck yourself in the face. I will wage a war on this issue that you cannot imagine.”

South African-born billionaire Musk and fellow tech executive Vivek Ramaswamy have both defended the use of H1-B visas to hire highly skilled workers for Silicon Valley and other key industries.

This flies in the face of the MAGA right’s anti-immigration doctrine of “America First,” which has quickly become a divide within the American political right.

As the online war of words heated up, Musk endorsed a post calling American workers too “crazy” to do high-skilled tech jobs that would hire foreign workers.

Ramaswamy, in turn, blamed U.S. sitcoms for extolling the virtues of dark characters over those with brains, necessitating hiring smarter people from other countries to fill technical roles.

“If we are truly serious about solving the problem, we must face the TRUTH: Our American culture has worshiped mediocrity over excellence for far too long,” Ramaswamy wrote.

He then called for changes in American child-rearing: “More math tutoring, fewer sleepovers…more creativity, less chilling.”

Musk also declared that “hateful, unrepentant racists” should be removed from the Republican Party “root and branch” and called his critics “despicable fools.”

At one point Musk wrote down

He added: “I will fight to the last drop of blood to ensure that it remains this land of freedom and opportunity.”

Bannon replied on Gettr: “Bring.It.Dude – All of It.”

In another post, he wrote: “American jobs for American workers: H1B visas are a TOOL of the tech oligarchs to keep wages low while destroying the spirit of American citizens.”

Bannon continued: “American citizens have never bowed to the British Empire, the Bolsheviks, the Nazis – we will not start with South Africa.”

On Friday’s edition of his podcast, he went further, saying tech leaders like Musk are “on the spectrum.”

“The nerds don’t take criticism,” he said. “They’re kind of, you know, they’re a little bit everything on the spectrum, right? They don’t know – they don’t have strong social skills.”

On Thursday, Musk was accused of personally punishing his critics, as “proud Islamophobe” Laura Loomer and other far-right activists claimed on his social media platform
