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 Wednesday that Petraeus, who resigned from the CIA post on Friday because of an extra-marital affair, indicated his willingness to testify.

"He is very willing and interested in talking to the committee," she said. No date for his testimony has been set.
