The Note: Trump Crosses the Border To Mexico

— -- NOTABLES

--WHAT THE CLINTON CAMPAIGN IS SAYING ABOUT TRUMP’S TRIP: From Clinton’s Communications Director, Jennifer Palmieri: “From the first days of his campaign, Donald Trump has painted Mexicans as "rapists" and criminals and has promised to deport 16 million people, including children and U.S. citizens. He has said we should force Mexico to pay for his giant border wall. He has said we should ban remittances to families in Mexico if Mexico doesn't pay up. What ultimately matters is what Donald Trump says to voters in Arizona, not Mexico, and whether he remains committed to the splitting up of families and deportation of millions.”

--WHAT TO EXPECT FROM TRUMP’S ‘MAJOR’ IMMIGRATION SPEECH: Donald Trump is going to be back out on the campaign trail today with his long-awaited speech that is slated to unveil the newest version of his immigration plan, ABC’s MEGHAN KENEALLY writes. The speech comes after Trump and his campaign staff differed when describing portions of his policy relating to immigration, indicating that there might be changes from what he has previously mentioned on the trail. The biggest change to Trump's immigration stance seems to center around the previously planned deportation force that would have been dedicated to removing people who now live in the United States but originally arrived illegally. In recent weeks, Trump has appeared to be wavering on what to do with some longstanding residents who have families and jobs and no criminal history. Trump's communications director Jason Miller previewed the speech on Tuesday on Fox News, saying that "nothing's changed with Mr. Trump's stance." http://abcn.ws/2bFvA0m
