kelly o'donnell, who has been watching this all unfold. kelly, this is not the end of it, by the way. he's meeting with aid workers and refugees, and then there's going to be a major address. i assume these things like this major address which the whole world will be watching are preplanned. but it does feel like -- like president biden's been gathering data points throughout this entire trip. the meetings in brussels, the nato meetings, then his visit to the border, then his meeting today with president duda and other polish officials, and now his visit to this convention center in warsaw. it all seems to be coming together into something that he's going to talk about this afternoon. >> reporter: i think that's a fair assessment. and the president is collecting those points of reference and personal touchstones that fill out the picture of the things that he needs to understand in order to make policy and to try to reinforce the coalition that he's already helped to lead and to bring together the allies.
