Because if his only argument is that a former President saying that he mentally declassified things while President actually declassified them, that argument will lose 9-0 at the Supreme Court. As it should.
49 minutes whining about the FBI raid. 5 minutes on policy. Hannity is a waste of time.
The courts rejected that argument out of hand:
"The Times cites no authority that stands for the proposition that the President can inadvertently declassify information and we are aware of none. Because declassification, even by the President, must follow established procedures, that argument fails." N.Y. Times v. CIA, 965 F.3d 109, 123 (2d Cir. 2020).
On this matter of classification and declassification a president’s judgement and word should be absolute. Who is the court to demand a president follow a “process” for identifying unclassified documents? They were in his possession at his residence under lock and key.
“What is the evidence that he deemed them unclassified while President?”
The proper question under the constitution is: What is the evidence he didn’t?
