To authorize something is to give authority to another person or persons. Exactly WHO is now authorized to declassify? I thought Barr already had this authority. What, then, is going to change?
Trump did not say, "I hereby ORDER immediate declassification and release to the public of all these documents without redactions." Now that would get my attention.
Twitter does not count as an official government order method, so he can’t say that there. He can do that at his desk through regular channels, though those don’t get published right away.
