So I read the indictment and it looks like he kept some of these documents as sort of evidence to defend a narrative against people like Miley or to use as evidence against decisions the Biden administration may make. I’m guessing “country A” is Iran and “country B” is Afghanistan.
Much of what is left, while highly sensitive, seems to be deemed as incidental or just Trump being his usual slob self.
Also, with the pictures, is obvious he was willfully reckless with national security information. Who really knows how many spies passed through Mar a Largo? But I would bet a lot of that stuff got compromised.
