Trump mulls pardon for Muhammad Ali

US President Donald Trump said Friday he was considering granting a posthumous pardon to boxing great Muhammad Ali, whose refusal of military service during the Vietnam War made him a champion of the US civil rights and anti-war movements. Ali, who died in 2016, was convicted of draft evasion in 1967 and sentenced to five years in prison, but the conviction was overturned on appeal by the US Supreme Court in 1971.
