This is why defense lawyers’ #1 piece of advice to every client they meet is ‘shut up’.Trump's public statement / defense is that he declassified the documents.
He's a special kind of stupid. This is a power he does not have. But Republicans are claiming it is real and it sounds good, so Trump goes for it.
Such a defense cuts off other notions, such as someone else did it! Someone else put it there. Not after he claims knowledge, ownership, etc.
He is cutting himself off from deniability through sheer stupidity.
