The seven former CIA directors, five former deputy directors and one former director of national intelligence wrote that “we all agree that the president’s action regarding John Brennan and the threats of similar action against other former officials has nothing to do with who should and should not hold security clearances — and everything to do with an attempt to stifle free speech. You don’t have to agree with what John Brennan says (and, again, not all of us do) to agree with his right to say it, subject to his obligation to protect classified information. We have never before seen the approval or removal of security clearances used as a political tool, as was done in this case.”
