Donald Trump and his personal attorney want to lay the foundation to discredit whatever Bob Mueller comes up with. They're essentially engaging in a scorched-earth litigation strategy that is beginning with trying to discredit the prosecutor.

I think what we are confronting now is a new war of ideas. It's not communism versus capitalism, but it is authoritarianism versus democracy and representative government. And that is a threat that here in Europe, they feel acutely. They've seen their countries interfered with, bombarded by cyber-attacks, by Russian propaganda, indeed, by Russian troops.

There are many reasons why the Russians prefer Donald Trump.I think, in the first instance, they wanted to tear down Secretary Clinton. They, I think, despised her remarks about the flawed 2011 elections in Russia. They feared that she would be very tough on Russia in terms of sanctions.

We need Democrats and Republicans in Congress to work together to fashion a very comprehensive pushback to Russia, not just the cyber-hacking, but their bribery of officials in Europe, their social media campaign, their overt media campaign.
