Gee, he was a double agent. And Zbig apparently didn’t know anything about it.
Or maybe he did.
Double agent : well, he was an employee of CIA but during his stay at Praha as CIA station chief, he sent informations to Moscow about all the CIA covert operation in the Czech Republic.
He never stopped to work for KGB. So he was no real double agent.
Is that surprising to learn a former communist agent was a close friend of one of the most important official of the Democratic Party ?
