The Guardian reported earlier that American counter-intelligence forces detected a Russian woman, who had been working for many years in the US Embassy in Moscow and had an access to classified information.
The woman was quietly dismissed previous year as the U.S. Secret Service sought to avoid public embarrassment on the matter, the Guardian reported, adding that Russian President Vladimir Putin's decision to order 750 U.S. diplomatic staff out of Russia served to create a smokescreen for her dismissal.
It was established she was having regular and unauthorized meetings with members of the FSB, Russia's principal security agency.
It said: "At no time, in any US Secret Service office, have FSNs been provided or placed in a position to obtain national security information".
According to the Guardian newspaper account, the woman had worked at the Embassy for more than a decade and had access to the intranet and email systems of the Secret Service, as well as its counterfeit-money tracking operations.
It is alleged that a woman was officially hired by the US Secret service.
After an investigation, the RSO reported this breach to the Secret Service in January 2017.
In a statement, U.S. Secret Service officials rejected the British paper's claims of a cover-up and high-level security breach as "categorically false" and said "the article is wrought with irresponsible and inaccurate reporting based on the claims of "anonymous" sources". However, the woman continued to work at the embassy for some time before the secret service "decided to let her go quietly months later, possibly to contain any potential embarrassment", says The Guardian.
Members of Trump's national security team said that US intelligence officials are anxious Russian Federation and perhaps other foreign powers will look to interfere in November's midterm elections.
The statement added: "As such, all Foreign Service Nationals are managed accordingly to ensure that Secret Service and United States Government interests are protected at all times". Foreign employees are relegated to "translation, interpretation, cultural guidance, liaison and administrative support" duties, specifically because they "can be subjected to foreign intelligence influence".

Declining to comment, the State Department simply said the following.
The state department later went on to concede the risk that foreign governments can pose to those employed by the USA government.
