An unidentified Russian woman who worked for the Secret Service as a liaison between the agency and Russia's law enforcement and intelligence agencies was having regular unauthorized meetings with members of Kremlin's Federal Security Service (FSB), according to the United Kingdom newspaper.
The Russian national, a woman, was hired by the U.S. Secret Service and came under suspicion in 2016 during a routine security sweep carried out by the State Department, according to sources quoted by the Guardian.
The regional security office alerted the embassy in January 2017 and the woman was dismissed last summer, after being caught red-handed, the official said.
"We figure that all of them are talking to the FSB, but she was giving them way more information than she should have", one state department official claimed.
According to U.S. officials, that was because she was being fed information in order for investigators to see for themselves that she was passing it along to Russian intelligence.
But the woman had access to "to the most damaging database, which is the U.S. Secret Service official mail system", The Guardian's source said.
In the published us intelligence agencies stated that every employee of a diplomatic mission could be "the objective of influence of foreign intelligence services".
"At no time, in any U.S. Secret Service office, have FSNs (Foreign Service Nationals) been provided or placed in a position to obtain national security information", the Secret Service said in a statement.
The report also claims that when the spy was finally outed, the Secret Service not only failed to launch an investigation, but tried to cover up the security breach by using the Russia-ordered expulsions of 750 US embassy staff members as a "cover for her removal".
Butina is accused of infiltrating a pro-gun rights organization in the U.S.at the behest of a high-powered Russian official, as part of a mission to influence US foreign policy towards Russia.
"This is of particular emphasis in Russian Federation", the agency added. "As a result, the duties are limited to translation, interpretation, cultural guidance, liaison and administrative support", it continued.
She was found to be actively providing Russians with intelligence.
Declining to comment, the State Department simply said the following.
The Russian was suspected of espionage division staff of the USA state Department, which handles security at US diplomatic missions.
