The Department of Justice is reportedly investigating multiple people with ties to Russian state media, weeks after federal officials warned that the Kremlin is attempting to influence the upcoming presidential election through the media.

The FBI has searched multiple individuals this month as part of the probe, including former U.N. weapons inspector and U.S. foreign policy critic Scott Ritter, and foreign policy commentator Dimitri Simes, US officials briefed on the investigation told The New York Times.
