Here's perhaps the juiciest paragraph from the Mueller filing:
"The defendant’s false statements obscured the fact that the Moscow Project was a lucrative
business opportunity that sought, and likely required, the assistance of the Russian government. If
the project was completed, the Company could have received hundreds of millions of dollars from
Russian sources in licensing fees and other revenues. 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 occurred 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. "
