as the principle advisor to ambassadors credits and stevens on security and law enforcement matters. i'm here today to provide testimony in support of your inquiry into the tragic events of september 11th, 2012. including the murders of ambassador stevens, sean smith, glen doherty, and tyrone woods. i had the pleasure of working with ambassador stevens during the final months of my tour in libya and would echo what many are saying. the loss of ambassador stevens is not only tragic for his family and sad for our country but his death will prove to be a devastate loss for libya, struggling to recover from its recent civil war. my family and i would like to offer personal condolences to the families of these four patriots who gave their lives in the service of their country.
