WASHINGTON — Democratic presidential candidate Joe Biden said Monday that he is putting Russia and other foreign governments “on notice” that he would act aggressively as president to counter any interference in U.S. elections. The statement came hours after Democratic leaders issued a new warning that Congress appears to be the target of a foreign interference campaign.
