The subpoena asked for records related to longtime Clinton aide Huma Abedin, who for several months in 2012 was simultaneously employed by the Clinton Foundation, the State Department and a private consulting firm with ties to the Clintons.

Abedin's work arrangement was approved after she was designated a “special government employee.”

In its report, the Post cited people familiar with the subpoena and written correspondence about it. The full scope of the investigation is unclear.

Last month, Clinton denied a Fox News report that the FBI had expanded its probe of her private email server to include ties between the State Department and her foundation, calling it “an unsourced, irresponsible” report with “no basis” in fact.

Republican lawmakers have accused Clinton of allowing large donations from foreign governments to the foundation to influence her decisionmaking as secretary of State.
