With news that Trump campaign manager is going to be indicted, revelations of secret meetings between trump officials and Russians, meetings the trump team members consistently lied about, it looks apparent that the evidence of interference and collusion is mounting to form an airtight case being prepared by Special Prosecutor Mueller.
A bit early. News that Mueller is getting Facebook information on Russia ad buys may indicate there is at least circumstantial evidence to show Trump and Russia bought ads at roughly the same time and aired identical fake news stories. But despite Mueller turning up the heat on Manafort to possibly break him with fines and loss of future income over tax filings, I just don't see who in Trump campaign could possibly have been Putin's partner in collusion.
If all he's got is strangely similar ad buys and the idiot son and SIL meeting with the Russian spy ... I don't see much. JMO
