"Since the November 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 Russians are believed to now have nearly 150 suspected intelligence operatives in the US, these sources said. Officials who spoke to CNN say the Russians are replenishing their ranks after the US in December expelled 35 Russian diplomats suspected of spying in retaliation for election-meddling."
