Sens. Patrick Leahy (D-Vt.) and Sheldon Whitehouse (D-R.I.), two members of the Senate Judiciary Committee, are pressing the Department of Justice to answer questions about President Trump’s pardons of U.S. soldiers accused of war crimes.

The Democratic senators want to know whether the Justice Department’s Office of the Pardon Attorney was involved in the decisions to pardon soldiers accused of unlawful military executions, including fatal shootings of unarmed civilians.

They also asked whether the Justice Department issued any advice or recommendations to the White House and whether it coordinated at all with the Department of Defense, where senior officials were initially opposed to the pardons.
