NBC News reports:
Presidential candidate Donald Trump faced questions about immigration policy from reporters Thursday at the U.S.-Mexico border amid roiling controversy about his bombastic style and his controversial remarks about Mexican immigrants. He did not respond to a question from NBC News regarding what he plans to do about the nation’s estimated 11 million undocumented immigrants. “First thing we have to do is strengthen our borders and after that we’ll have plenty of time to talk about it,” he said. Asked if his tour of the border yielded any evidence to support his claim that Mexico is “sending criminals” over the border, Trump promised to produce documentation but offered no details. “We’ll be showing you the evidence,” he said, declining to elaborate.
