"We're watching and monitoring it closely." Secretary of State Marco Rubio confirms U.S. officials are closely tracking reports of a suspected plague breach at a Russian research laboratory. The concern follows reports that a Russian lab technician was infected and died, triggering localized quarantine measures in the region.
