President Trump on Monday pardoned a former US Army first lieutenant convicted of killing an Iraqi prisoner, the White House said.

Michael Behenna, of Oklahoma, was sentenced in 2009 to 25 years in prison for unpremeditated murder in a combat zone after killing a suspected al-Qaida terrorist in Iraq. He was paroled in 2014 and had been expected to stay on parole until 2024.

Behenna, now 35, stripped detainee Ali Mansur naked, interrogated him without authorization and then shot him twice, according to The Washington Post. He claimed he acted in self defense.

Press Secretary Sarah Sanders said Behenna was a “model prisoner” while serving his sentence and “entirely deserving” of clemency.

Behenna’s case attracted support from the military, Oklahoma elected officials and the public, Sanders said.
