Following the announcement, 15 former senior intelligence officials and 60 other high-ranking former CIA officers protested the Trump decision in an open letter saying, "... former government officials have the right to express their unclassified views on what they see as critical national security issues without fear of being punished for doing so." Calling Brennan "one of the finest public servants I have ever known," retired Navy admiral William H. McRaven addressed President Trump in an op-ed saying, "I would consider it an honor if you would revoke my security clearance as well, so I can add my name to the list of men and women who have spoken up against your presidency."
