Tech billionaire Elon Musk tested the boundaries of foreign election interference on Thursday, hosting Alice Weidel, co-leader of the far-right Alternative for Germany (AfD), on his social media platform six weeks before Germans head to the polls.

In a conversation with AfD leader Alice Weidel on X, Musk concurred with her assertion that Adolf Hitler was a communist and pushed disinformation about migrants coming into the US.

God! Martians! A “communist” Hitler! It was heavy on oddness and light on policy as the X owner and the AfD co-leader hit it off.
