(CBS News) The top Democrat on the House Oversight and Government Reform Committee, Rep. Elijah Cummings, D-Md., said the investigation into the death of four Americans in Libya is becoming a “witch-hunt.”

On “Face The Nation” he said Republican statements about the attack are “basically based on a campaign schedule, trying to give Romney some talking points. I don’t think that our men who were killed deserve this. I don’t think our diplomatic corps deserves this. We can do better.”

Cummings’ counterpart, Rep. Darrell Issa, R-Calif, who is Chairman of the House Oversight Committee, has a different take. He said on the same program that “we need to get to the truth. We need to get it real-time, and we need to quit having people say something is true when long afterwards they know it isn’t.”

Issa compared Obama administration statements about the Libya attack to when President George W. Bush declared the war in Iraq won in 2003.
