A Democratic lawmaker hurled profanity at White House deputy chief of staff Stephen Miller on Wednesday, going on to imply that Miller is a Nazi.

Rep. Mark Pocan, D-Wisc., made the statement on social media in response to some of Miller’s commentary on New York City. Miller was discussing democratic socialist Zohran Mamdani’s victory in the Democratic primary for New York City’s mayoral election, saying unchecked immigration was a major contributor to the city’s leftward slide in recent years.

“NYC is the clearest warning yet of what happens to a society when it fails to control migration,” Miller wrote.

Pocan chimed in: “Racist ****. Go back to 1930’s Germany.”

Pocan weighed in on Mamdani’s win multiple times, lashing out at another user who claimed the democratic nominee, who is Muslim, supports “Sharia Law.”

“I love watching MAGA nut jobs spinning total bull**** to overcome blatant racism and xenophobia,” Pocan responded to the post. “People want progressive populism that focuses on making their lives better, not redistribution of wealth from working people to the wealthiest. Trumpism is on the decline.”

Republicans have capitalized on Mamdani’s victory as evidence of the extremism of the current Democratic Party. The National Republican Congressional Committee (NRCC) was among the first to make the connection.

“The new face of the Democrat Party just dropped, and it’s straight out of a socialist nightmare,” they wrote in an email.

Aiming to tie House Democrats to Mamdani, NRCC spokesman Mike Marinella argued that “every vulnerable House Democrat will own him, and every Democrat running in a primary will fear him.”

Rep. Elise Stefanik of New York, a top ally of President Donald Trump who is seriously considering a run for Empire State governor next year, also pounced. Stefanik claimed that “a radical, Defund-the-Police, Communist, raging Antisemite will most likely win the New York City Democrat Mayoral primary.”
