I'm convinced he is knowingly acting as a Russian agent, either by choice or unwilling coercion. He's not the only one either. That whole gang of GOP bloodsuckers who spent the 4th July in Russia are all up to their necks in it; it's not even subtle.
I know Rand Paul wasn't one of them, nor Lindsey Graham or Moscow Mitch, but every decision or public statement they have made in the last 4 years has benefitted Uncle Vlad in one way or another, either directly spreading Russian disinformation, or undermining US democracy.
