From CBS, this story:
Twelve former senior intelligence officials, including 11 former CIA directors and deputy directors and one former director of national intelligence, have signed a letter of support for former CIA director John Brennan, calling the signal sent by the White House's decision to strip him of his security clearance "inappropriate" and "deeply regrettable."
I have put the entire text of the letter below the fold, and included the link for the Google Document where it is found. It is not listed as copyrighted.
Who signed it?
former Directors of Central Intelligence William Webster, George Tenet and Porter Goss;
former CIA directors Gen. Michael Hayden, Leon Panetta and Gen. David Petraeus;
former director of national intelligence James Clapper;
former deputy CIA directors John McLaughlin, Stephen Kappes, Avril Haines, David Cohen and Michael Morell
Worth noting that Hayden was also head of NSA, and both McLaughlin and Morell served as acting directors of CIA.
Also worth noting that Goss was a Republican Congressman from Florida before heading CIA, and that Webster also headed the FBI.

STATEMENT FROM FORMER SENIOR INTELLIGENCE OFFICIALS
As former senior intelligence officials, we feel compelled to respond in the wake of the ill-considered and unprecedented remarks and actions by the White House regarding the removal of John Brennan’s security clearances. We know John to be an enormously talented, capable, and patriotic individual who devoted his adult life to the service of this nation. Insinuations and allegations of wrongdoing on the part of Brennan while in office are baseless. Since leaving government service John has chosen to speak out sharply regarding what he sees as threats to ournational security. Some of the undersigned have done so as well. Others among us have elected to take a different course and be more circumspect in our public pronouncements. Regardless, 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. Beyond that, this action is quite clearly a signal to other former and current officials. As individuals who have cherished and helped preserve the right of Americans to free speech – even when that right has been used to criticize us – that signal is inappropriate and deeply regrettable.
Decisions on security clearances should be based on national security concerns and not political views.
