Actually you didn’t declassify anything. I don’t know what constitutional section you are referring to that allowed you to classify or declassify anything, but as far as I know you can not do such activities. The only legislation that allowed you to do anything of that sort was this, A Bill to Establish Classified Documents (1/2) & (2/2), and this was nullified a long time ago. So if I am missing something please do bring it forward,
Speaker of the House,
