The GOP chairman of the House Armed Services Committee said Thursday he is satisfied with how the military responded to the deadly attack on the U.S. diplomatic mission in Benghazi, Libya.

Republicans are pressing ahead with multiple congressional investigations, but Rep. Howard “Buck” McKeon, R-Calif., said the military did what it reasonably could during a chaotic night of two separate attacks on Sept. 11, 2012. The assault killed four Americans, including U.S. Ambassador Chris Stevens.
