WASHINGTON » 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 the U.S. ambassador and three other Americans.

Sen. Dianne Feinstein, D-Calif., said today that 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.

She said his testimony to her committee will be limited to the Benghazi attacks that killed U.S. Ambassador Christopher Stevens and three others. No date for his testimony has been set. Petraeus was CIA director at the time.
