The Independent in Britain reported this last week...
We know what Russia wants from Trump...what does Russia have on Trump...???
1. Massive loans..??
2. Tapes..??
3.  It is not goodwill.  Trump has never done anything out of the goodness of his heart.  It is not confirmed he has one.  And Kushner's father went to jail in 2000.
I think it is business loans from 2010 and maybe tapes.  This is also curious:
