Detroit Bomb Suspect: No coat, no luggage; Congress plans hearings on how he got through

Congress got its first behind-the-scenes look at the airline bombing Wednesday, and officials said the security failures were even worse than President Barack Obama outlined last week. It remains unclear, however, how those failures will be fixed.

"He was flying into Detroit without a coat. That's interesting if you've ever been in Detroit in December," New Jersey Democrat Rep. Bill Pascrell, a member of the House of Representatives' Homeland Security Committee, said after a briefing by presidential counterterror adviser John Brennan.

National Intelligence Director Dennis Blair and National Counterterrorism Center Director Michael Leiter briefed the House Intelligence Committee in private, and Brennan took questions from the House in overlapping sessions Wednesday.

Congress wants to know how Obama plans to improve an intelligence system that failed to recognize the significance of repeated warning signs that Umar Farouk Abdulmutallab was planning an attack. The Nigerian also showed up at the Amsterdam airport without any luggage - another sign that officials acknowledge should have prompted more scrutiny.
