(1) If you are the CIA Director, you damn well better have a bunch of Communist spy contacts.
(2) Some CIA agents are former spies from other countries. Some American CIA agents have become spies for other countries. They all know each other.
If the concern is that Commies are taking over the CIA, well, that ship already sailed and it is in a race with all the other government agencies who are stocked with communist/socialist/organized crime infiltrators.
Sounds like you’re basing your post only on the title of the article. I’ve been known to do the same myself. :)
The issue is Panetta’s close connections and friendships with communists going back to the 60’s and 70’s, not any communists he may have bumped into during his current CIA gig.
