New allegations of a State Department cover-up?

Updated

NBC News has obtained documents tied to ongoing investigations at the State Department involving eight cases of alleged misconduct by state department workers, contractors, and a United States ambassador. The incidents reportedly occurred during Hillary Clinton’s tenure, according to the documents.

An internal Inspector General memo from last October reported the ambassador under investigation “routinely ditched his protective security detail in order to solicit sexual favors from both prostitutes and minor children.” The report also states that a high-ranking official at the State Department directed investigators to “cease the investigation.”

The ambassador, whom NBC News has chosen not to identify, denied all allegations.

While refusing to comment on the specific investigations, a state department spokesperson said “the notion that we would not vigorously pursue criminal misconduct in a case, in any case, is preposterous.”
