>> congresswoman chrissy houlahan, former congresswoman donna edwards, thank you both so much for starting us off today on a day like this. i'm grateful. john heilemann is sticking around with us. when we return we will be joined by former cia director john brennan and retired four star general mccaffrey to talk to them about how we failed to see this coming. the speed with which the taliban has advanced has surprised everyone as we brace for the fall of the afghan government. plus, the urgent need nor the january 6th committee to investigate not just what happened on that day but the flood of new details we are learning about the disgraced ex-president's pressure campaign to overturn an election he lost. what we know about how long we can expect the delta variant to circulate in this country from other countries where it has already left as the white house marks the biggest vaccination day in more than a month. that's good news. "deadline: white house" continues after a quick break. don't go anywhere. millions of vs struggle to get reliable transportation
