Could be useful as a trap.
Biden (to his cabinet): I proposed a partial pardon to Trump.
Cabinet: WTF, are you serious?
Biden (to his cabinet): Nah, I just want to steal his thunder and get under his skin. Of course we won’t pardon him for the January 6th insurrection and his violation of secrecy of the National Archives Classified materials. I just want to use his playbook on political pardons against him. I believe we could provoke him into admitting some additional details of his misdeeds that are outside the scope of the “limited” pardon.
Cabinet: As long as the Attorney General, FBI, Secret Service, US Marshall’s have vetted this plan, go for it.
Ad Hoc Pardon Team: Ooooh, I like that plot twist.
Biden (publicly): I would like to invite a special guest to the White House to receive a special (limited) pardon…
Biden (publicly): (With Trump in attendance) I would like to extend a pardon to, … Edward Snowden, as Edward Snowden has a better concept of right and wrong compared to my predecessor and failed to responsibly exercise his pardon power, and used it as a political bludgeon instead.
