Story highlights The Washington Post first reported on that the Clinton Foundation had received a subpoena Thursday

It came from the State Department's Inspector General

(CNN) A representative for the charitable foundation set up by Bill and Hillary Clinton confirmed they received a subpoena from the State Department's Inspector General, but said they are not the focus of the government watchdog's investigation.

The Washington Post first reported on the subpoena Thursday, saying it was sent to The Clinton Foundation last fall, and sought "documents about the charity's projects that may have required approval from the federal government during Hillary Clinton's term as secretary of state," as well as records on Clinton aide Huma Abedin. The Post report said there is no indication the Inspector General is looking at Clinton herself.

A foundation representative would not comment on details of the subpoena. The representative did say that the investigation has been narrowed since the initial subpoena and that the Clinton Foundation was not the focus of the Inspect General investigation.

A spokesperson for the Inspector General's office declined to comment.

The nature of the Inspector General's inquiry is unclear, but the revelation is the latest in a series that have brought increased scrutiny to Hillary Clinton's tenure as Secretary of State.
