WASHINGTON (CBSDC) — Uncovered documents show the U.S. State Department may have covered up allegations of illegal behavior ranging from sexual assaults to an underground drug ring.

CBS News reports that is has unearthed documents from the Diplomatic Security Service (DSS), an internal watchdog agency, that implicate the State Department in a series of misconducts worldwide.

The memo, reported by CBS News’ John Miller, cited eight specific examples, including allegations that a State Department security official in Beirut “engaged in sexual assaults” with foreign nationals hired as embassy guards and the charge and that members of former Secretary of State Hillary Clinton’s security detail “engaged prostitutes while on official trips in foreign countries” — a problem the report says was “endemic.”

Former State Department internal investigator Aurelia Fedenisn told CBS News, “We also uncovered several allegations of criminal wrongdoing in cases, some of which never became cases.”

Often times, other DSS agents were simply told to back off of investigations of high-ranking State Department members. Fedenisn told CBS that “hostile intelligence services” allow criminal behavior to continue.

In one such cover-up, investigators were told to stop probing the case of a U.S. ambassador who was suspected of patronizing prostitutes in a public park. The memo states that the ambassador was permitted to return to his post despite having, “routinely ditched…his protective security detail” in order to “solicit sexual favors from prostitutes.”

A draft of the Inspector General’s report on the performance of the Diplomatic Security Service, obtained by CBS News, states, “Hindering such cases calls into question the integrity of the investigative process, can result in counterintelligence vulnerabilities and can allow criminal behavior to continue.”

Fedenisn was part of the team that drafted the whistleblower report, and CBS News reports that two hours after the charges were reported, investigators from the State Department’s Inspector General showed up at her door.

A statement to CBS News states, “It goes without saying that the Department does not condone interference with investigation by any of its employees.”
