Musk said in a Thursday public appearance his security detail should potentially be bigger and that he was “open to ideas” on improving his security.

The US Marshals Service has deputized members of Elon Musk’s private security detail, giving them certain rights and protections of federal law enforcement agents, three law enforcement officials familiar with the matter told CNN.

Musk has expressed concern about his security for months, as he has been promoting his plan to gut the federal government.
