Switzerland-based Glencore Ltd, a subsidiary of Glencore plc, said Tuesday it received a subpoena on July 2 from the U.S. Department of Justice to produce documents and other records concerning compliance with the U.S. Foreign Corrupt Practices Act and U.S. money-laundering statutes.

The requested documents “relate to the Glencore Group’s business in Nigeria, the Democratic Republic of Congo, and Venezuela from 2007 to present,” the company said in a statement.

Glencore was cited hundreds of times in the Panama Papers. It then came under heavy criticism in the Paradise Papers—the sequel to the Panama Papers—which revealed that Glencore loaned tens of millions of dollars to Dan Gertler, an Israeli businessman with close ties to Joseph Kabila, president of the Democratic Republic of the Congo.

Glencore said it is reviewing the subpoena and “will provide further information in due course, as appropriate.”
