Rep. Maxine Waters, a Democrat from California and the ranking minority member of the House Financial Services Committee, on Friday said she was concerned about recent press reports a Justice Department criminal investigation into Russian trades made by Deutsche Bank has "gone dormant." In a letter to the department, Waters demanded to know the present status of the investigation. Early this year, Deutsche Bank DB, -2.39% paid over $600 million to settle with U.S. and U.K. bank regulators over a scheme that involved more than 2,400 pairs of "mirrored" trades that regulators said lacked economic purpose and could have been used to move money out of Russia.
