I assumed he was on the phone to his boss, Putin, frequently.
My impression is that Trump has been part of Putin's money laundering team for years. They launder Russian oil money via offshore banks into US property and international golf courses.
This is Putin's mafia operation. Trump's destruction of evidence is an extension of the mafia omerta.
I don't see him as vulnerable so much as he is a part of the criminal enterprise. This isn't a risk of damage. It's actual damage done by Putin's US team. He has taken over several Eastern European countries. Now he is taking hold of the US as well.
The battle is with the institutions. First the courts. Now the House.
