The Situation Room with Wolf Blitzer

According to the Pentagon, U.S. troops are moving to Afghanistan in rapid speed "as we speak," in in response to "deeply concerning" Taliban takeover. The Taliban is trying to isolate Kabul, but the city is "not in an imminent threat environment," according to the Pentagon. U.S. troops could possibly be "going into harm's way" in Afghanistan and will have the right of self-defense. The Pentagon will not say if moving troops into Afghanistan is a combat mission or not. However, the U.S. Embassy in Kabul is instructing personnel to destroy sensitive materials. The Pentagon will adjust the deadline for drawdown of U.S. troops in Afghanistan if necessary. 

The Pentagon is concerned about Kabul's "lack of resistance" against the Taliban.
