In an interview with BBC News to promote his new book Saving Justice, former FBI Director James Comey said President-elect Joe Biden should “consider” pardoning his predecessor Donald Trump when he takes office on Jan. 20th.

Asked if Biden should take a page from Gerald Ford, who pardoned Richard Nixon in 1974, Comey replied, “I don’t know. He should consider it.” While he said he’s not sure Trump—who has reportedly floated the idea of pardoning himself—would accept such a pardon, he added, “As part of healing the country and getting us to a place where we can focus on things that are going to matter over the next four years, I think Joe Biden is going to have to at least think about that.”

Of course, a presidential pardon would only protect Trump from federal charges and not the many state crimes for which he is currently under investigation.
