A new lawsuit is alleging that top State Department officials violated record-keeping laws by using “secret” channels to discuss diplomatic moves on Ukraine, specifically President Donald Trump’s desire for Ukrainian officials to investigate former Vice President Joe Biden and his family.

In the complaint filed Tuesday in the U.S. District Court for the District of Columbia, the groups Citizens for Ethics and Responsibility in Washington, the National Security Archive and the Society for Historians of American Foreign Relations asked for a court order requiring the State Department to preserve the communications.
