Trump may pardon Ali who doesn't need one

US President Donald Trump says he may pardon boxing champion Muhammad Ali, who doesn't seem to need one.

And for futures acts of clemency, he may seek recommendations from pro football players and other athletes who have protested racial injustice by kneeling during the national anthem.

Trump said that "instead of talk", he is going to ask protesting players to suggest "people that they think were unfairly treated by the justice system". The president said football players have "seen a lot of abuse" and "a lot of unfairness" and that he wants their input on his use of this executive power.

Trump told reporters on Friday as he left the White House for a meeting in Canada with US allies that his team was "looking at literally thousands of names" of people for potential pardons because they were treated unfairly or their sentences are too long.

Ali is one name on this list, Trump said, though it was not immediately clear why Ali would need a pardon because he has no criminal record. The Supreme Court overturned his conviction for resisting the draft in 1971.

Ali was born Cassius Clay, and changed his name after converting to Islam in the 1960s. He refused to serve in the Vietnam War because of his religious beliefs, declaring himself a conscientious objector and saying, "I ain't got no quarrel with the Viet Cong."

Ali was stripped of his heavyweight crown in 1967. Ali's legal fight ended in 1971, when the Supreme Court ruled in his favour. He regained the boxing title in 1974. Ali died in 2016.

Trump already has granted a posthumous pardon to boxing's first black heavyweight champion, Jack Johnson, more than 100 years after what was seen as a racially charged conviction. Johnson was convicted in 1913 by an all-white jury of violating the Mann Act for travelling with his white girlfriend. That law made it illegal to transport women across state lines for "immoral" purposes.

Earlier this week, Trump commuted the life sentence of a woman whose cause was championed by Kim Kardashian West.
