Actual real life clearances take between 6 - 12 months or longer depending on backlogs.
These people have zero actual “vetting” but “presidential authority” can just say to give them clearances on the spot which is what happened here.
So they have the legal bit of paperwork but it doesn’t actually mean anything. It was just an override of the regular checks and balances and would you believe it it turns out it’s filled with problems precisely like the process is designed to stop.
