As we explained many, many times, who does and does not get sensitive information is entirely the purview of the president.
No matter how much the little junior Deep State minions hate it, no matter how many USAID bought out journalists rant against it, Donald Trump is president with all the powers and perogatives that other presidents have.
Elon Musk is a
Special Government Employee, which is not a new thing that Trump invented.
Special Government Employees
A "special Government employee" (or "SGE") is an officer or employee in the Executive Branch of the Federal Government who is appointed to perform important, but limited, services to the Government, with or without compensation, for a period not to exceed 130 days during any period of 365 consecutive days. This status is important because the ethics rules apply differently to individuals who qualify as SGEs versus other Federal employees and officials.
Show me anywhere that says that the president cannot provide sensitive information to an SGE. If you can't, stop making up rules, or blindly following liars.
