refugees appear to be ending up at this point. >> garrett, evacuating people off of the tarmac in kabul is the first step of an unbelievable difficult process. they landed at the air force base. this is a major american military facility. and then they need to be screened. we need to figure out exactly who people are. there is often a lot of confusion at kabul, it is not possible to fully vet everyone. many of the people that land here are then transferred onward to other u.s. facilities, across europe, across ramstein airport in germany. that is a military facility that is turned into something of a makeshift refugee camp well as a security screening.
