blinken is expected to speak in a couple of hours to layout the specific number of americans evacuated from afghanistan and the number that remain in afghanistan. the president and his national security advisor jake sullivan have committed that every american who wants to leave afghanistan will be evacuated by that august 31st deadline. the numbers have been pretty capab cagey over the last several days. the president yesterday made clear he believes they are on pace to achieve the goals they set out in the evacuation. that is why he's sticking to that august 31st deadline. what that achievement looks like has been somewhat amorphous over the last couple days. the real question right now and i'm hearing this a lot from lawmakers on capitol hill, democrats and republicans, is what that means for afghans.
