on pbs. e.b. stoddard, columnist and associate editor at "real clear politics." thanks to all of you for being with us. robert, let me start with you. it's not your story, your paper is reporting, though, we just quoted from it, the president apparently feeling some urgency to show tangible progress on this border wall by election day 2020. obviously the signature promise of his 2016 campaign. behind the scenes, how big a concern is that for trump, that so little progress has been made in 2 1/2 years as president? >> inside the white house tonight, they're bracing for a fall where the u.s. mca trade deal may not even be brought to the floor for a vote, where a china trade deal may be long away on the horizon. so they're trying to look at executive authority as a way to try to galvanize that republican base, the president's core voters for 2020.
