President Donald Trump on Friday said he was considering pardoning the late boxing champion Muhammad Ali.

He added that he was thinking about pardoning "some others," including people who "have sentences that aren't very fair."

He said he had a list of 3,000 names of people who were being considered for clemency.

President Donald Trump on Friday said he was thinking "very seriously" about pardoning the late boxing champion Muhammad Ali, who refused to be drafted into the Army during the Vietnam War and whose conviction was overturned by the Supreme Court in 1971.

"Look, he was not very popular then," Trump told reporters on the South Lawn of the White House. "Certainly his memory is very popular now. I'm thinking about Muhammad Ali. I'm thinking about that very seriously."

Ali's attorney Ron Tweel said in a statement Friday morning that, because of the Supreme Court's reversal of Ali's conviction, Trump's pardon wasn't needed.

"We appreciate President Trump's sentiment, but a pardon is unnecessary," Tweel said. "There is no conviction from which a pardon is needed."

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 before commuting the sentence of Alice Johnson, a 63-year-old woman who was serving a life sentence for her first drug offense.

Trump also said Friday that he was thinking about granting clemency to "some others," adding that he had a list of 3,000 names. Those under consideration included "folks that have sentences that aren't very fair," Trump said.

It's unclear whom Trump was referring to, but his commutation of Johnson on Wednesday prompted speculation that Trump could commute the sentences of people similarly convicted of nonviolent drug offenses and given lengthy prison terms under harsh drug sentencing popularized during the 1980s and '90s.

"There will be more pardons," Trump said. "I thought Alice yesterday was beautiful. I thought Jack Johnson — which was recommended by Sylvester Stallone and some great boxers — I thought Jack Johnson was a great one."

Trump has also previously floated pardoning Martha Stewart and commuting the 14-year sentence of Rod Blagojevich, the former Illinois governor.

In response to one reporter's question, Trump also confirmed one name not on his list for potential pardons: O.J. Simpson.

"No, I'm not thinking of O.J. — only you could say O.J.," Trump said.
