How will the Kabul airport attack influence the US evacuations?

Well, so far it looks like President Biden is on track to keep the August 31st deadline for evacuating, for finishing evacuations and leaving Afghanistan fully. However, there's still somewhere in the range of about a thousand American citizens, plus potentially tens of thousands of special immigrant visa holders who are Afghani citizens that helped the United States, that could potentially be left behind because of this expedited withdrawal schedule. This is a real risk for Biden.
