Lawmakers stormed out of classified Afghanistan briefing after their questions weren't answered

Multiple lawmakers angrily stormed out of a classified briefing with members of the Biden administration on Afghanistan on Wednesday morning, according to three sources familiar with the briefing.

The Republican and Democratic lawmakers grew frustrated after State Department, Pentagon, Department of Homeland Security, and Office of the Director of National Security officials failed to answer their basic questions during the briefing for members of the House Foreign Affairs Committee, the sources told CNN.

tate Department officials -- both privately and publicly -- continue to say that about 100 Americans are still in Afghanistan who want to get out. Some lawmakers have told CNN they do not understand that accounting, given the department has said that they evacuated more than 75 Americans from Afghanistan through evacuation efforts in the last few weeks. State Department officials have said that the dynamic situation on the ground is the reason they cannot give a more precise figure.
