Chutkan will hold a trial within a trial to decide whether the indictment is valid or whether the acts evidenced are covered by immunity. It is for the judge to decide whether to hear oral argument (probably yes) and on what points. I would expect a decision in favour of the prosecution. After that, I expect Trump to appeal, arguing that he has immunity. Anticipate it finishing in POTUS with looney tunes Maga judges. This will run and run. Trump may die before a trial begins. Two years of argument? What a system but
@Dax777 tells us it is a minor issue.
