Somehow, I missed this EO that Trump issued when he took office on Jan 20. It basically says security clearances are too much of a pain so we'll just go ahead and grant full clearances (TS/SCI) for six months to anyone the White House counsel and the acting CIO designate.

I think this pretty well explains how Mr. Big Balls got his clearance.

Therefore, by the authority vested in me as President by the Constitution and the laws of the United States of America, I hereby order:

1. The White House Counsel to provide the White House Security Office and Acting Chief Security Officer with a list of personnel that are hereby immediately granted interim Top Secret/Sensitive Compartmented Information (TS/SCI) security clearances for a period not to exceed six months; and

2. That these individuals shall be immediately granted access to the facilities and technology necessary to perform the duties of the office to which they have been hired; and

3. The White House Counsel, as my designee, may supplement this list as necessary; and

4. The White House Counsel, as my designee, shall have the authority to revoke the interim clearance of any individual as necessary.
