I think some people have a hard time with the notion that Trump is a Russian asset, because they think that means he's a KGB agent with associated spying skills.

That's not what it means. All it means is that he is being handled by Russia. It just means that he gives them what they want. It doesn't have to mean anything other than that. It doesn't even have to mean that he is knowingly subverting the United States.

And yet, he is doing it knowingly. His diesel deal is all the evidence (1)
