Donald Trump on Monday issued “full, complete and unconditional” presidential pardons for about 1,500 people who were involved in the January 6 attack on Congress, including some convicted of violent acts, making good on his promise to act in such cases on day one of his second term.

In addition to the pardons, he issued commutations for more than a dozen cases, shortening sentences for those that he said needed “further research”. Among those whose sentences were commuted was Stewart Rhodes, the founder of the far-right Oath Keepers militia.

“This is a big one. We hope they come out tonight, frankly,” Trump said while signing the pardons in the Oval Office on Monday night after he referred to those convicted as “hostages”.
