The term is and was Collaborator. To this day he’s actually proud of what he did. Just another financial transaction to benefit himself- appalling he laughs about it, matter of fact without regard to the thousands he stole from for his Nazi pals. He and his sons are... criminals. Hungary will eventually get him and his spawn.
