RIO GRANDE RECONNAISSANCE for The New York Times

“Despite President Trump’s calls for a massive wall to secure the border — which Representative Henry Cuellar, a Texas Democrat, ridiculed as a “14th-century solution to a 21st-century problem” — the fight against illegal immigration and drug trafficking on the United States-Mexico border has increasingly become high tech…
