I'm not sure who owns whom. There was a lot of reciprocity going on, especially about that Ukraine business.
I've always felt Mr. Putin was holding something over Trump's head ~~ and NOT the pee tapes with prostitutes in a Moscow hotel room. That would barely make a ripple among Trump supporters.
There has to be something worse that would ruin Trump financially because money is all he cares about.
I know it sounds unlikely but Mr. Putin could have copies of Trump's tax returns ~ maybe as a pre-requisition for that 'Trump Tower Moscow' he was lusting after for years.
