It is honestly scary that a guy that dumb (and/or dishonest) was running the CIA at some point. Read his actual statement closely:
“While I was at CIA, Senator JOHN McCain ripped me a new one on several occasions,†Hayden tweeted on Sunday. “But not once did he think I shouldn’t have a security clearance. Go figure. RIP, American hero.â€
Trump didn't take a security clearance from someone who was "AT CIA." He took from from someone who "USED TO BE at CIA." Either Hayden is too stupid to understand the distinction, or he knows the difference, but thinks he can get away with making an inherently dishonest statement. What a putz....
