"Surely Dems would be anxious to find some evidence and there are enough Dems on this forum.   I had not heard about this and find it fascinating.........Well???"

You have heard nothing because it is a stupid challenge. Maybe the Dems are too busy with real work to chase down all the ridiculous river of shit floaters that Faux News and its followers (you may not be one, but you are sure acting like one) set sailing with not a shred of real evidence.

Now go to Snopes and follow the links to interviews with roomates, professors, school newspaper articles, etc.

Well????? yourself Bucko!
