He should be vigorously defending the US, and aggressively trying to get to the bottom of it. Instead, he's actively obstructing the investigation and thwarting US defenses. In short, he's doing the opposite of what he should be doing as president. He's acting like a damn mole using the office to further his own interests and those of his business associates, including Russia.
At worst Trump is a traitor, and at best he's grossly derelict of duty. How this is not front and center of US political discussion on all sides, including the GOP, befuddles me.
This also seems critical to interpreting Trump's voter fraud commission, as the Russia efforts were focused on voter registration. I predict Trump will somehow spin what was being reported on in this article into something having to do with voter fraud. That is, "let's not talk about Russian hacking of voter registration records, as that's just speculation. We agree, though, that there are anomalies in the voter registration records, and given that we all agree on that, it's time for voter ID laws."
