WASHINGTON (AP) — The chairman of the House Armed Services Committee says he's satisfied with the military response to the deadly attack on the U.S. diplomatic mission in Benghazi, Libya.

Republican Rep. Howard "Buck" McKeon says the military did what it reasonably could during a chaotic night of two separate attacks. The Sept. 11, 2012, assault killed four Americans including U.S. Ambassador Chris Stevens.

Republicans are still pressing their investigation, with five committees pursuing what happened. McKeon says the retired general who headed the Africa command testified behind closed doors for some seven hours on Wednesday.

McKeon says he was told lawmakers heard nothing new in the testimony.
