MSNBC: Trump Visits California Today to Inspect Border Wall Prototypes
WELKER: "Well, first of all, this is President Trump’s first trip to California as president. He’s going to be touring prototypes of his border wall. Of course, that’s really a key campaign promise, building this wall, and a lot of his supporters feel as though he hasn’t been aggressive enough about actually making that happen. So the optics today will be powerful in that regard. He’s also going to talk to troops here at Miramar in San Diego a little bit later on today. He’s heading into a deep blue territory, of course, and he has really been what the governor has described at war with this state over its immigration policies."
