Don’t think he could get A security clearance
He could not. His father was foreign-born and he still had relatives in Kenya. That right there would cause his application to be crumpled up and tossed into a burn-bag. And right now, this individual sans provenance has access to our most closely-guarded secrets, sources and methods. He also was known by another name. He went to foreign schools. Any number of these discriminants would stop any further background investigation. I doubt if there are any members of his cabinet who would qualify for any security clearance.
