Elon Musk urged an audience at a German far-right political rally not to feel “guilty” about their country’s history. The surprise speech comes less than a week after he was accused of making a “Sieg Heil”-style salute while giving a speech during President Donald Trump’s inauguration.

The billionaire was received by cheers while addressing a rally for Alternative for Germany where he told attendees they shouldn’t be ashamed of their history.
