WASHINGTON – President Donald Trump has pardoned a former U.S. Army commando set to stand trial next year in the killing of a suspected Afghan bomb-maker and a former Army lieutenant convicted of murder for ordering his men to fire upon three Afghans, killing two, the White House announced late Friday. The commander in chief also ordered a promotion for a decorated Navy SEAL convicted of posing with a dead Islamic State captive in Iraq. White House press secretary Stephanie Grisham said in a written statement that the president is responsible for ensuring the law is enforced and that “mercy is granted,” when appropriate. “For more than 200 years, presidents have used their authority to offer second chances to deserving individuals, including those in uniform who have served our country,” she said.
