On a purely legal level, there are no criminal charges, so a pardon isn’t the way to go. Lack of standing is the obvious counter argument, because the only entity with standing to complain about unauthorized access to executive branch data is ... the executive branch.
But like most partisan federal judges, this guy will not be dissuaded by the facts or the law. IMO,Trump should carry on. Meanwhile have Bondi intervene in the case and move for dismissal based on lack of standing.
What happens in the meantime, though? DOGE and Musk will be delayed.
