The watchdog group Citizens for Responsibility and Ethics in Washington filed a lawsuit Tuesday seeking to compel special counsel Henry Kerner and his office to file a complaint against top Trump White House aide Kellyanne Conway for Hatch Act violations.

The lawsuit, filed in the U.S. District Court for the District of Columbia, claims the special counsel has adopted a policy of no longer filing complaints with the Merit Systems Protection Board for non-Senate confirmed executive branch officials’ Hatch Act violations.
