Petraeus on Capitol Hill to discuss Libya attack

11/16/12:  The New York Times reports Former CIA Director David Petraeus arrived early Friday for closed hearings on Capitol Hill as lawmakers seek details from the retired general about the Sept. 11 attack on the U.S. Consulate in Benghazi, Libya, that killed the U.S. ambassador and three other Americans. Republicans and some Democrats have demanded an explanation of why the Obama administration initially described the attack at Benghazi as a protest gone awry, leading to the deaths of U.S. Ambassador Christopher Stevens and three others, including two Navy SEALS.
