Groups of hundreds of Africans, Haitians and others from Central and South America continue to trudge across the U.S.- Mexico border in record numbers, despite promises from Mexico to help stop the massive migration.

Footage from the Del Rio Sector of the border in Texas shows scores are making their way in mini-caravans, with many arriving well-dressed in designer clothes, toting luggage and backpacks with their children in tow.
Last year, the Trump administration spared product categories including Apple’s smartwatch and AirPods wireless earbuds from an initial round of duties. But the administration’s proposal to impose additional tariffs of 25% covering $300 billion in imports from China would affect all of Apple’s major devices, including the Mac, iPhone and iPad.

While it shifts Mac Pro production to China, Apple more broadly is considering moving some of its assembly work out of China because of concerns about U.S. tariffs, The Wall Street Journal reported last week. One of the people familiar with Apple’s plans said that same consideration could extend to the Mac Pro, with Ireland as an alternate possible site.

The Mac Pro’s history reflects the hurdles to doing assembly in the U.S. The previous Mac Pro model—known as the “trash can” because of its stumpy, cylindrical appearance—was the first computer Apple had made in the U.S. in about a decade. Mr. Cook, who had engineered Apple’s outsourcing to China, announced plans to build the product in the U.S. in late 2012, when Apple was facing major scrutiny over its reliance on manufacturers in China and those contractors’ treatment of workers.
