A suspected Russian spy was employed for more than a decade at the US Embassy in Moscow before being fired last year, according to CNN news. 

The woman, a Russian national, worked for the US Secret Service for years before she came under suspicion during one of the State Department regional security office's routine security reviews in 2016, the official said.

The security office found the woman was having regular, unauthorized meetings with the Russian intelligence service, the FSB.The woman had access to the Secret Service's intranet and email systems, but the official said "She did not have access to highly classified information."
