But the conviction Ali would be pardoned for - evading the draft during the Vietnam War - was already overturned by the U.S. Supreme Court. He received a draft-evasion conviction in 1967 and was stripped of his world heavyweight title. When the Supreme Court heard his case in 1971, all eight judges ruled in Ali's favor.
Trump has ramped up the use of his executive clemency power in recent weeks, granting pardons to the late heavyweight boxing champion Jack Johnson and the conservative pundit Dinesh D'Souza, then commuting the sentence of 63-year-old Alice Johnson, who was serving a life sentence for drug offenses.

"I had a doctor that gave me a letter - a very strong letter on the heels", Trump said, though he did not provide the letter or remember the name of the doctor.
Ali won a gold medal in boxing at the 1960 Olympics. Last week, the president said he was considering pardoning Martha Stewart and commuting the sentence of former Illinois Gov. Rod Blagojevich.
