Donald and Melania Trump touched down in southern France Saturday amid high tensions and low expectations for the president’s third G7 summit. Host Emmanuel Macron has already anticipated a lack of unity among the leaders by announcing that there will be no final document from the weekend gathering. Trump’s first official engagement will be a formal dinner at the base of a lighthouse overlooking the posh French resort town of Biarritz on the Atlantic coast. Formal talks will begin Sunday morning.
