I agree with those saying that this exonerates the Trump team from Russian collusion. But, my first idea was that this was also meant to DISCREDIT the Mueller investigation. It's clearly bogus and they're literally indicting a ham sandwich (caterers). They're not going to be able to do anything to the Russians, and it shows just how big of a waste of money this all is. So, I think discrediting themselves may also be part of this op.
