From the Special council filing re the referenced Trump Hotel in the Cohen submission.
"If the project (Trump Hotel) was completed, the Company could have received hundreds of millions of dollars... The fact that Cohen continued to work on the project and discuss it with Individual 1, well into the campaign was material to the ongoing congressional and SCO investigations, particularly because it occured at a time of sustained efforts by the Russian government to interfere with the U.S. presidential election. Similarly, it was material that Cohen, during the campaign, had a substantive telephone call about the project with an assistant to the press secretary for the President of Russia."
THE ABOVE IS EVIDENCE.
Whether or not you or I think it is conclusive does not change that it is evidence that Mueller has already filed with the Courts.
This is only one piece of many pieces of evidence already presented only because it had to be as it was attached to necessary filings re Cohen.
