There is no direct evidence to support the claim that Elon Musk's maternal grandparents, Joshua N. Haldeman and Winnifred "Wyn" Josephine (Fletcher) Haldeman, were "Nazi party members in Canada," nor that they moved to South Africa "because they supported apartheid."

X users believe Elon Musk did "the Hitler salute", also known as the "Nazi salute", in a huge inauguration blunder. The billionaire made the eerily similar gesture when he slapped the podium and raised his flat hand into the air.

A gesture associated with the Nazis has a surprising history. But in Germany, there was little doubt about its meaning.
