The Department of Justice has long taken the position that criminal charges can’t be brought against a sitting president because that would “undermine the capacity of the executive branch to perform its constitutionally assigned functions” (true enough). As long as that remains the Department’s position, Attorney General Jeff Sessions couldn’t bring charges even if he wanted to, which he doesn’t. But that’s not quite the same as saying that whether the president violated a criminal law “misses the point.” It matters because it is perhaps the most egregious in a string of incidents that underscore the president’s disdain for the rule of law… and also has some relevance to a little something that begins with the letter “i.”
