Bill Burr is continuing to slam Elon Musk. The outspoken comedian shared last month that his account on X, the social media platform Musk acquired when it was still known as Twitter, was flagged after he mocked the billionaire for what Burr called “Sieg heiling” during an inaugural celebration for President Donald Trump.

Comedian and actor Bill Burr fired at Elon Musk, calling him “evidently a Nazi,” and criticized liberals for their lack of response to the tech giant’s political influence, on an episode of NPR’s Fresh Air Monday.
