Why does anyone who is no longer with the government still getting Top Secret info? All FORMER employees should have their clearances revoked.
Do you realize how many private sector people and firms are doing sensitive work for the government? It would ball everything up if they immediately lost clearance when they left direct govt. service and had to start all over - it can take many months even for lower level clearances.
Certainly, someone who’s proven himself a loose cannon and a leaker should be revoked; and Trump will do that when he sees fit. But to change the entire process would bog down innumerable essential services.
