WASHINGTON - Former CIA Director David Petraeus has arrived for a closed hearing on Capitol Hill before the House Intelligence Committee as lawmakers get 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.

Petraeus is not expected to testify about his affair with biographer Paula Broadwell or the harassing emails she sent a Florida woman that led to the FBI investigation that uncovered the affair.

Petraeus will testify later Friday before the Senate committee.
