Benghazi

In spite of all the evidence and secret meetings and refusing testimony, why would anyone not want the truth about Benghazi. I'm not saying I know all the truth, I'm saying the death of four Americans demands it be told. People like David Brock claims a hoax like he has all the facts, and the left eats it up. How can he claim to know what happened when the house oversight committee doesn't have all the facts. Document are being withheld and witnesses intimidated. Am I the only one who is sceptical?
