A major Clinton Foundation donor company that has been granted millions in U.S. federal loans has been linked to a corruption probe in Pakistan, according to reports.

The Abraaj Group, a Middle Eastern investment fund that contributed between $500,000 and $1 million to the Clinton Foundation, has not been charged in the case, but its name has surfaced in Pakistani media reports. Authorities in Sindh province have accused a prominent government official of providing illegal favors to K-Electric, a power company owned and managed by the Abraaj Group since 2009.

Former Pakistani oil minister Dr. Asim Hussain was arrested last year amid allegations that he helped harbor terrorists in a string of hospitals he owned and doled out illegal contracts to companies, including K-Electric. Both Hussain and K-Electric have denied the allegations.

The investigation has not impacted the U.S. government’s ongoing partnership with the Abraaj Group, which dates back to at least 2012. That year, the Overseas Private Investment Corporation—a federal agency that dispenses corporate loans under the guidance of the U.S. State Department—selected the Abraaj Group to manage its $150 million Middle East investment fund.

Two weeks later, the Abraaj Group co-sponsored the Clinton Global Initiative’s annual meeting.

Last October, the Overseas Private Investment Corporation again pledged up to $250 million to help fund the Abraaj Group’s K-Electric operations. The announcement came less than a month after the Sindh Rangers, a Pakistani law enforcement agency, reportedly issued a 12-page report accusing Hussain of passing illegal favors to K-Electric.
