US President Donald Trump on Friday pardoned a former soldier convicted of murder and a Green Beret charged with killing a suspected Taliban bomb-maker, defying warnings that the move would be an abuse of the powers afforded him under the US Constitution. Trump dismissed a second degree murder conviction against Army First Lieutenant Clint Lorance, who is six years into a 19-year term for ordering soldiers in 2012 to fire on three unarmed Afghan men on a motorcycle, two of whom died. “Many Americans have sought executive clemency for Lorance, including 124,000 people who have signed a petition to the White House, as well as several members of Congress,” said a White House statement released Friday.
