I suppose that could be a connection.  But Russia has smart folks who can do research, (if this is a state sponsored attach this is a certainty).     I'll wait for evidence of such shared information before assuming it's true.   If it is, that's a very damning piece of evidence that would show collusion

Lets let the investigator figure out if this a real lead.

It seems obvious to me that the Trump clan had a serious financial interest in conducting business with the  Russian state, (this is not a free market for investment in any way, it requires friend in high places in most athoritarian nations.)  This is a fact we know and without minimum financial disclosure by Trump, it's very hard to measure look for influence.     

Why this isn't seen by Trump supporters as a real problem and conflict of interest is surprising to me.  I think of conservatives as 'realist', not insisting of financial disclosure seem idealistic.   Yes politics can be corrupt, buy so can private profit seeking.
