This week's bonus episode of Up First comes from NPR's daily business podcast The Indicator from Planet Money. The U.S. trade deficit reached over 75 billion dollars in June. There are more imports than exports and transportation industry bottlenecks are making it worse. Container ships have to wait for days to unload cargo, railyards are overflowing with cargo, trailer trucks are stuck on the roads, and warehouses are filled with goods. Meanwhile, cargo ships are leaving American ports empty and American exporters are having trouble getting their products to Asia. NPR economics correspondent Scott Horsley and Sally Herships look into what's happening.
