MEXICO CITY: Mexico’s foreign minister and the visiting governor of California questioned on Monday (Tuesday in Manila) plans by Texas to deploy troops to stem the flow of immigrant children, saying they need humanitarian aid instead. Gov. Jerry Brown, on a visit focused on boosting trade with California’s southern neighbor, said the Texas plan must be a short-term measure and that he hopes “wiser minds will prevail over the next several months.” The Democratic politician was referring to a plan announced last week by Texas Gov. Rick Perry, a Republican seen as a potential 2016 presidential election candidate, to send 1,000 National Guard reservists to the enormous and porous border US-Mexico border. More than 57,000 children, mostly from Central America, have entered the United States illegally and without adult supervision since October, many fleeing unrelenting gang violence in their home countries.
