HONOLULU (CNN) - The Obama administration conducted two secure briefings on Wednesday for Congressional staffers about the attempted terror attack on Northwest Flight 253 that left key aides with still a lot of unanswered questions about what went wrong, according to two Congressional officials familiar with the sessions.
One of the officials familiar with the briefings said the takeaway was that "there are still lots of questions Congress will be asking about what could have been done differently and what will be done differently in the future" to prevent attacks.
The official added that Obama officials who conducted the briefings told the Congressional staff that it "appears there wasn't enough negative information prior to the incident to take any severe measures" such as putting the eventual suspect, Umar Farouk Abdulmutallab, on the No-Fly List to prevent him from boarding the plane.
The Congressional official said the two briefings occurred Wednesday morning in a secure room of the Capitol for key Congressional staffers because most lawmakers are traveling outside Washington because of the Congressional recess for the holidays. At least one lawmaker, Rep. Pete Hoekstra, R-Michigan, was in Washington and did attend.
The first briefing was for Democratic and Republican staffers of the House and Senate Intelligence Committees. The second session was for a broader group of committees in both the House and Senate that included Intelligence as well as the Armed Services, Commerce, Judiciary, and Homeland Security panels.
The briefings were conducted by officials from various departments and agencies including: The FBI, the Justice Department, the Transportation Security Administration, the Customs and Border Patrol, the State Department, and the Office of the Director of National Intelligence.
In a sign of the Obama administration trying to coordinate its message on the matter, officials said that the White House will be conducting a conference call with Democratic press secretaries from the House and Senate on Wednesday afternoon.
