Ali's pardon would be for a draft-evasion conviction, that results from his refusal to enter the military during the Vietnam War. Ali was stripped of his heavyweight crown in 1967. However, the Supreme Court ruled in his favor in 1971, ending his legal battle.
Trump told reporters Friday his team is "looking at literally thousands of names" of people who have come to their attention because they've been treated unfairly or their sentences are too long. I'm thinking about that seriously.
Ali eventually became licensed again, however, and he went on to have a storied boxing career that lasted until 1981.
Kim Jong Un’s letter to Trump has people wondering: why so big?
He added that much of the diplomacy must also be assisted by the DPRK's regional neighbors like South Korea, Japan and China. The historic meeting between Mr Trump and Kim Jong-un would be the first between sitting U.S. and North Korean leaders.
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. There's a slight problem with pardoning Ali though: His conviction was already thrown out. Reality TV star Kim Kardashian West personally appealed to Trump to pardon the 63-year-old grandmother.
He did not offer any other names, but said in response to a reporter's question that O.J. Simpson wasn't on the list.
"The power to pardon", said Trump, "is a lovely thing". Add Donald Trump as an interest to stay up to date on the latest Donald Trump news, video, and analysis from ABC News.
