I think that pulling all of their clearances would not go well over politically. I think a better approach would be, via executive order, place all the X-employees or office holders in a “not need to know” category. They could be re-instated on a case by case basis if necessary.
They would keep the clearance but it would make it a very serious offense for anyone to share information with them. If after the 5 year renewal period they still didn’t have a need to know, then let their SC lapse.
5 years to get rid of them? I don’t agree. The bureaucracy badly needs trimming. The day they are terminated or retire they should lose their clearances as would happen in any business. Just plain COMMON SENSE!
These azz hats use their security clearance to secure lucrative employment and contracts.
