This scoop, from Robert Costa and Karen De Young at The Washington Post, is just bizarre: Donald Trump is considering jetting to Mexico City on Wednesday for a meeting with Mexican President Enrique Peña Nieto, just hours before he delivers a high-stakes speech in Arizona to clarify his views on immigration policy, according to people in the United States and Mexico familiar with the discussions. I heard about this on Rachel Maddow's show before I read the Poststory, and I tried to figure out what the hell the Trump people are thinking.
