After all, how can investigators determine the extent of ties between the Trump campaign and the Russians without examining financial records (up to and including tax returns) of the candidate? It's hard to make the case that those records wouldn't be relevant to determining what connections, if any, existed. Depending on what information the intelligence community has already gathered, Trump's financial records may become critical to determining the Trump family associations with the Russians. If Democrats have control of one House, he could well face a subpoena. In any event, continuing to stonewall requests for such evidence will be interpreted by many voters as evidence of illicit conduct.
