Musk has spent days bounding in and out of meetings, sitting in on phone calls, weighing resumes and traveling to Washington as Trump’s unofficial co-president.

Musk has been so aggressive in pushing his views about Trump’s second term that he’s stepping on the toes of Trump’s transition team and may be overstaying his welcome at Mar-a-Lago, Trump’s home in Palm Beach, Florida, according to two people familiar with the transition who have spent time at the resort over the past week.
