Krauthammer's views on this aren't mine.   

His view is the "I love it" response damns DJ as a collusionist.  

That someone "loves" possible evidence of a candidates collusion with Russia is evidence of their own collusion?   This makes no sense.

We can't forget the meat of the proffered evidence by this Russian lawyer (or her publicist) --  that it was Hillary who was colluding with Russia.

To just hear those views (which ultimately didn't exist) is collusion?   

This is all nothing, and it will come to nothing.
