A conservative watchdog group has called for another federal investigation into Hillary Clinton’s communications during her time as Secretary of State, accusing Clinton of giving special government access to an investor in a deep-sea mining company because of his connections to Clinton’s son-in-law.

The group, called the Foundation for Accountability and Civic Trust (FACT), plans to file a complaint with the U.S. Office of Government Ethics on Monday.

“It appears that then Secretary Hillary Clinton gave a private company special access to the State Department based upon the company’s relationships with Secretary Clinton’s family members and donors to the Clinton Foundation,” the group says in the complaint first obtained by TIME.
