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.

Musk, 53, spoke to a crowd of Trump supporters at Capital One Arena in Washington, D.C., after Trump was sworn in at the U.S. Capitol. While thanking the supporters, Musk put his right hand over his heart, then extended his arm out with his palm down. He then turned around and repeated the gesture.
