In evaluating whether evidence about collective action of multiple individuals constituted a crime, we applied the framework of conspiracy law, not the concept of "collusion." In so doing, the Office recognized that the word "collud[e]" was used in communications with the Acting Attorney General confirming certain aspects of the investigation's scope and that the term has frequently been invoked in public reporting about the investigation. But collusion is not a specific offense or theory of liability found in the United States Code, nor is it a term of art in federal criminal law. For those reasons, the Office's focus in analyzing questions of joint criminal liability was on conspiracy as defined in federal law. In connection with that analysis, we addressed the factual question whether members of the Trump Campaign "coordinat[ed]" — a term that appears in the appointment order-with Russian election interference activities. Like collusion,
"coordination" does not have a settled definition in federal criminal law. We understood coordination to require an agreement-tacit or express-between the Trump Campaign and the Russian government on election interference. That requires more than the two parties taking actions that were informed by or responsive to the other's actions or interests. We applied the term coordination in that sense when stating in the report that the investigation did not establish that the Trump Campaign coordinated with the Russian government in its election interference activities.
