All of that was set-up in 2003-2006 under the bush administration in response to 9/11 and came to light during that same administration.

Obama didn't do much about it... However, he did eventually (second administration) declassify the FISA courts that Bush Jr. set up and him and his administration took steps to automate and improve the disclosure of such programs and other evil shit with the FOIA improvement act in 2016.
