U.S. Attorney General Eric Holder rarely raises his voice. But at the very end of a three-hour congressional hearing on Tuesday he was in a virtual shouting match with Virginia Republican Representative Frank Wolf.

Wolf, questioning whether valuable intelligence was lost, was furious about the initial hourlong interrogation of Umar Farouk Abdulmutallab, the Nigerian man captured after trying to ignite a bomb aboard a U.S. commercial jetliner on Christmas Day last year. USA/

“There were so many things that were missed,” Wolf said during the hearing.

He suggested that photos of detainees released from the U.S. prison in Guantanamo Bay, Cuba, should have been shown to Abdulmutallab amid concerns that some may have joined militant groups. Wolf said Abdulmutallab also should have been shown a picture of an American-born cleric believed to be in Yemen and tied to al Qaeda militants.

“Did you see this man? Did you see this man? Did you see this person? You didn’t have enough time to do that,” Wolf said. “So there was an opportunity that was missed and we’ll never get it back again.”
