"Executive Order 13526 was issued on December 29, 2009 by United States President Barack Obama. It is the latest in a series of executive orders from US Presidents outlining how classified information should be handled. It revokes and replaces the previous Executive Orders in effect for this, which were EO 12958 (text) and EO 13292 (text)." wiki
Listen up, pilgrims! The system of classifying most US government information originates in an Executive Order, not in federal law.
If you watched the senate hearing yesterday presided over by Lindsay Graham it quickly became evident that he was to some extent channeling Roy Cohn in the long ago Army-McCarthy hearings (1954). I was a boy then but, freaky kid that I was, I was glued to our tiny black and white TV set to watch. "Have you no sense of decency left? " Lawyer Welch asked Senator Joe McCarthy. I had the feeling yesterday watching Senators Feinstein and Whitehouse try to torture responses into new meanings that this was a "star chamber" proceeding in the fullest meaning of the term. A clear example was Feinstein's attempt to twist the former AG's statement that Flynn "could have been compromised" into "Flynn compromised the national security of the US." It seems evident to me that a certain element in the Democratic Party is intent on portraying both Flynn and Trump as traitorous agents of Russis.
Well, pilgrims, life is not just a bowl of cherries and fire should be fought with fire. The president is the ultimate declassification authority. As noted above, the classification and security clearance structure and procedures are created thought Executive Orders (with the exception of atomic energy information). In other words, with that exception, the president can declassify anything that is presently classified.
It is not a crime to talk to Russian officials. Flynn talked to the Russian ambassador on circuits that were commercial and unencrypted telephones. Presumably they spoke in English. The whole world knows that these conversations took place. The New York Times revealed this to the world after someone in the government told them. The whole world knows that all capable governments eavesdrop on foreign government officials. This is a secret without effective secrecy. Was the information collected by a cooperating foreign service? Well, that is just too bad! The political situation in the US is so toxic that exceptional disclosures by the US government are justified.
IMO, the president should declassify the transcripts of the intercepted Flynn/Russian ambassador conversations and the present DNI should release them himself at a presser with release of hard copies of the documents to the press.
If Flynn was guilty of something more than chatting with this Russian diplomat or any others, the transcripts will show that. pl
