Trumps tax returns, and I mean in total with all the endless schedules included, must be released and examined. Until that happens any possible financial connections between Trumps enterprises and the Russians (or anyone else for that matter) will be purely speculative.
Of course, if all of this were reversed and the current POTUS--whoever that might be-were a Democrat, you could bet that the din for the release would be so loud that we would all suffer hearing loss.
Funny how that works.
Get your facts first, then you can distort them as you please.
