If the president took them, they are declassified under the presidential records act. For him to say, after the fact, I couldn’t declassify them now has no bearing on whether they were declassified when he took them from the White House.
Yeah its possible he didnt remember if he declassified them or not..its automatically declassified regardless..4 yrs in office he had access to THOUSANDS of documents, how would he know this particular one he never declassified so its bogus regardless
