How many former employees still have keys to the building once they have become former employees?
And how many media persons would retain their jobs if they were critical of their media employers? Brennan is not employed by the govt and can, and does, say whatever he wants at any time but he is not entitled in any way to a govt security clearance. If these former high level govt employees have a security clearance, however limited, then every ex govt employee at any level is also entitled to have one. Yank them all, top to bottom. Renew when necessary.
