As the backlash against Elon Musk continues after the Tesla CEO made a straight-arm, Nazi-like gesture during his speech Monday at U.S. President Donald Trump’s inauguration, the billionaire posted a series of Nazi-related puns on X Thursday to his more than 210 million followers.

Elon Musk, billionaire adviser to President Donald Trump, leaned into the accusations that his Monday salute was a “Sieg heil” gesture with a series of trollish Nazi puns on X. “Don’t say Hess to Nazi accusations!” Musk wrote Thursday, referring to German Nazi Party leader Adolf Hitler’s deputy, Rudolf Hess.
