[Alberta's Child]

However, unfortunately, there is little evidence to show that he did declassify any of the documents that are cited in the indictment against him.

The President of the United States has no obligation to formally "declassify" anything. And without making any official statement about these materials he can establish any limited form of "declassification" that he wishes -- e.g., that he can determine that he can use the material freely but refuse to share it with anyone else (reporters, political advisors, etc.).

The Espionage Act which he is charged under never mentions the status of the material, just that they contain defense information . What it does mention is whether the possessor has reason to believe the material could be used to cause injury to the United State or to the advantage of any foreign nation.

Not only that the law presumes the material is given over by one means or another to someone not entitled to receive it. Just mentioning it does not meet that criteria.

However the above is moot because the President is not subject to the Espionage Act.
