@thechriskidd The Department of Defense does not have primary jurisdiction or authority to investigate US citizens collaborating with Russia for criminal or counterintelligence purposes within the United States. The DOD's role primarily involves national defense and military operations. Investigations related to collusion or collaboration with foreign entities such as Russia fall under the purview of other federal agencies, such as the Federal Bureau of Investigation , the Department of Justice , and the intelligence community. The FBI, in particular, is responsible for conducting counterintelligence investigations, and the DOJ is responsible for prosecuting criminal cases. If there are credible allegations or evidence of US citizens collaborating with Russia that involve national security concerns, the appropriate authorities will investigate and take appropriate action in accordance with the law.
