>> As many of you saw, the president ordered the expulsion of dozens of Russians intelligence officers.>> Does kicking out Russian spies really work? Current and former officials told Reurers at least in America, its unlikely. The US kicked out 60 alleged operatives over the use of the use a nerve agent on ex-Russian spy in the UK.
However, other Russians spying in America have worked or hacked their way into schools and the government, even companies like Microsoft. And in recent years, sources say Russia's switched up its methods of espionage in the United States, using a much wider variety of tactics than in the past. And as Reuters Jonathan Landay explains, they've also got advantage in numbers.
>> The Russians are said by former and current US officials to maintain an extremely large and robust intelligence presence in the United States. That goes for regular intelligence officers posing as diplomats, or what's known as using diplomatic cover, and illegals, who are Russian agents or Russian intelligence officers in the United States posing as non-diplomats.
>> Keeping tabs on spies in America falls on the FBI, not the CIA, but following so many potential spies, especially those who aren't working out of embassies, is a huge challenge.>> The FBI has to devote somewhere around ten agents for a 24 hour period, to track a single Russian operative.
That's because they have to keep watch on the exits and entrances of buildings, they have to watch multiple elevators, they have to even keep track of changes of cars and even hair pieces.>> The change in Russia's spy tactics has reportedly been a major project of Russian president Vladimir Putin, himself a former KGB agent.
Now Russia's spies don't only chase intelligence, they want influence and trade secrets in America's corporate world. As one former U.S. official put it, Russia used to have one way of doing things, now Putin has let a thousand flowers bloom.
