On September 11, 2012, terrorists attacked our consulate in Benghazi, Libya, and murdered four Americans, including our ambassador. Eight months later, we have learned some of what happened, but many questions remain.

This week the House of Representatives will hold a hearing on Benghazi, because we still don’t know all the facts about how we responded during the seven and a half hours of attacks, why we could do nothing to save the lives of Ambassador Chris Stevens, Sean Smith, Glen Doherty, and Tyrone Woods, and what, if anything, we have done to deter future attacks against Americans by holding the responsible parties accountable.
