Petraeus said to be shocked by girlfriend's emails
CIA Director David Petraeus was shocked to learn last summer that his mistress was suspected of sending threatening emails warning another woman to stay away from him, former staff members and friends told The Associated Press.


Petraeus, who led US military efforts in Iraq and Afghanistan, resigned his CIA post Friday, acknowledging his extramarital affair with his biographer-turned-lover and expressing deep regret. The scandal has rocked Washington, where members of Congress demanded to know why a months-long probe that ended the former general's storied career was kept quiet for so long. (AP)
