Elon Musk was reportedly engaged in what witnesses described as a "massive blowup" and "huge explosion" during a heated discussion with Donald Trump's adviser Boris Epshteyn. The incident took place at the dinner table at Trump's Mar-a-Lago club. Musk accused Epshteyn of leaking details of Trump's transition to media but Epshteyn said he didn't know what Musk was talking about.
