the SCO had corroborating evidence
The corroboration was regarding Cohen and Manafort.
Only the Cohen evidence implicated Mr Trump in campaign finance violations. So ... pay the fine and we get "No collusion".
As far as the Moscow Tower ... everyone lied, so what is the crime? No one cares about the lie, however, what is of interest is the nexus of Russian meddling and Trump's campaign. The reason this is of interest is there could be a possibility of conspiracy. Unfortunately the only evidence presented involved Cohen and his lies, and the possibility Mr Trump had knowledge of the negotiations.
So we can speculate that all that elbow rubbing produced babies or we can wait to see if there really is some evidence of a conspiracy. All it really means is investigators are in the House.
