Gen. David Petraeus resigned as CIA director Friday, citing an extramarital affair. Officials confirm Petraeus’s affair surfaced during an FBI probe of his email, and his biographer Paula Broadwell. Broadwell is being investigated for improperly trying to access his email. In a resignation letter to the White House, Petraeus wrote that he had been married for 37 years and exercised “extremely poor judgment” in cheating on his wife, Holly, who has also worked for the Obama administration. President Obama saluted Petraeus for his “extraordinary service” and added that CIA Deputy Director Michael J. Morrell will take over as acting director. The Senate Intelligence Committee says Petraeus will no longer testify at next week’s closed hearings on Benghazi. Let the conspiracy theories begin.
