In addition to the fact that Ali's conviction was eventually overturned, President Jimmy Carter issued a blanket pardon for draft evaders in 1977.
Ali eventually became licensed again, however, and he went on to have a storied boxing career that lasted until 1981.
Asked if he will pardon former campaign aides such as Paul Manafort, indicted by special counsel Robert Mueller, Trump said, "They haven't been convicted of anything". I'm thinking about that seriously. According to USA Today, if granted it would make Ali just the fourth posthumous pardon in history.
Trump's musing about an Ali pardon was blasted by the Rev. Al Sharpton, who accused the president of "nothing more than grandstanding".
The president also called on the National Football League and its players to give him recommendations for pardons. He was fined $10,000 and faced a five-year sentence in prison.
"This was quite a surprise to everybody this morning when we heard about it", he said Friday during a phone interview. Reality TV star Kim Kardashian West personally appealed to Trump to pardon the 63-year-old grandmother.
He told reporters outside the White House Friday, that he is considering granting clemency to at least 3,000 more people - including Ali.
