Since the 2016 U.S. presidential election took place, Russia has been collecting intelligence there more actively. CNN reported that with reference to its sources among former and active U.S. officials.
Former top-rank CIA officer Steve Hall maintains Russian spies are aiming for more information about plans of Trump’s administration. "Whenever there is a deterioration of relations between countries — the espionage and intelligence collection part becomes that much more important as they try to determine the plans and intentions of the adversarial government," Hall said as quoted by the outlet.
According to CNN, since the election, ‘US intelligence and law enforcement agencies have detected an increase in suspected Russian intelligence officers entering the US under the guise of other business, according to multiple current and former senior US intelligence officials’.
The U.S. intelligence believes the Russians could be employing about nearly 150 suspected intelligence operatives in the U.S.
