Billionaire's estranged daughter has used rival social media platforms to attack Trump's anti-transgender executive order, and her dad's salute.

In an Instagram story later posted to X by conservative radio host Dan O’Donnell, Kuffel captioned an image of Musk, “Dude Nazi saluted twice. TWICE. During the inauguration. You f--k with this and this man, I don’t f--k with you. Full stop.”

While speaking to a crowd of MAGA faithful on Monday, Elon Musk made a grunting noise, placed a hand on his heart and extended it outwards in a quick, snapping motion, palm facing down. He then repeated the motion for the people behind him.
