Beyond the two FBI field offices, FBI counterintelligence agents based in Washington are pursuing leads from informants and foreign communications intercepts, two of the people said.
This counterintelligence inquiry includes but is not limited to examination of financial transactions by Russian individuals and companies who are believed to have links to Trump associates. The transactions under scrutiny involve investments by Russians in overseas entities that appear to have been undertaken through middlemen and front companies, two people briefed on the probe said.
Reuters could not confirm which entities and individuals were under scrutiny.
