The Russia investigation was lost for Trump almost from the very beginning because one of the first things that Mueller did was get his tax returns. The Russia scandal is often treated as separate from the Cohen crimes, but scandals have one common thread at their core. They are both about money and financial crimes. Robert Mueller has had Trump’s tax returns from the day that his investigation began. Trump could try to shut down Mueller tomorrow, but the damage has already been done. Robert Mueller knows what Trump has done and how Trump did it.
