JD Vance and Susie Wiles pushed Elon Musk to repair his relationship with President Trump after the tech billionaire blew up at the president in a dramatic and public falling out, according to people familiar with the matter. In a call last Friday, the vice president and the White House chief of staff urged Musk to put an end to the feud.

President Trump and Elon Musk traded social media barbs last week. Mr. Trump has said that he has no interest in repairing the relationship with his former adviser.
