The Clinton Foundation was subpoenaed last fall by State Department investigators for records relating to charity projects that might have come before the department when Hillary Clinton was secretary of state, a source confirmed Thursday.   

The development was first reported by The Washington Post. A representative for the Bill, Hillary and Chelsea Clinton Foundation confirmed the details to Fox News.

The Post first reported that the State Department inspector general subpoena sought documents on foundation projects that might have needed approval from the department during Clinton’s tenure in charge.

The subpoena also reportedly sought records on Clinton aide Huma Abedin.

Abedin has come under scrutiny for serving for several months in 2012 in multiple roles – working for the department and the foundation, as well as Clinton herself and a consulting firm

And multiple media reports over the past year – seized upon by Republicans -- have raised questions about whether foundation donors used their contributions to seek influence with the State Department.

The Clinton presidential campaign has rejected such assertions. Meanwhile, questions about Abedin’s role and the foundation largely have been overshadowed by the controversy over Clinton’s use of a personal server and email system while secretary. That matter is under investigation by the FBI.

According to the Post, the scope and status of the IG inquiry that prompted the subpoena is not clear. A foundation official told the newspaper that the foundation is not the focus.
