The head of the Senate Intelligence Committee says former CIA Director David Petraeus has agreed to testify to Congress about the Sept. 11 attacks on the U.S. Consulate in Benghazi, Libya, that killed U.S. ambassador Chris Stevens and three other Americans. Sen. Dianne Feinstein says Petraeus, who resigned from the CIA post on Friday because of an extra-marital affair, indicated his willingness to testify. No date for his testimony has been set.

What will Petraeus say? We may not know because the testimony will be behind closed doors. Frank Wuco is a retired U.S. Naval Intelligence Officer and former chief of Intelligence Operations at Special Operations, Command Central.
