Trump announced the pardons in November, 2019.

One soldier, Maj. Mathew L. Golsteyn, killed an unarmed Afghan that he suspected of being a bomb-maker. He was convicted of second-degree murder.

The other, 1st Lt. Clint Lorance, gave orders to open fire on unarmed Afghan civilians, resulting in two deaths. He was sentenced to 19 years in prison.

Neither intervention was welcomed by military leaders. Defense Secretary Mark Esper warned that this would undermine the military code of justice.

Trump has also intervened on behalf of other soldiers convicted of war crimes, including a Navy SEAL whose own unit had turned against him.

A year later, Trump pardoned four former Blackwater contractors convicted of perpetrating a massacre.
