US President Donald Trump said on Friday he is considering pardoning some 3,000 people, including late boxing champion Muhammad Ali, whose conviction for refusing to join the US military during the Vietnam War was later vacated by the US Supreme Court.

The president, speaking to reporters before he departed for a Group of Seven summit in Canada, also said he will reach out to NFL players who have been urging criminal justice reforms for their recommendations of people who have been treated unfairly.
