Getting a security clearance, particularly a high-level clearance takes a long time. They send investigators to interview people you've worked with, check records, etc. It can take over a year for a normal person. The only way I see these people getting clearances this quickly is if they just skipped the background investigation, on orders from senior people in the Trump administration.
And there's just no way they would have given Big Balls a clearance through the regular process.
