An electric car company started by Virginia’s Democratic gubernatorial nominee Terry McAuliffe is under a federal investigation.

According to a report by the The Washington Post, the Security and Exchange Commission subpoenaed documents in May from GreenTech Automotive, a company for which McAuliffe served as chairman until late last year. The SEC also requested banking information from Gulf Coast Funds Management, a McLean company run by a brother of Hillary Clinton that helped fund GreenTech.
