DAVID MUIR: We are also tracking the images coming in from Venezuela tonight, where the government says Nicolas Maduro has been re-elected to a third six-year term, although full voting data has not been released. The U.S. tonight and other South American nations are expressing concern and have not recognized the results. Tonight, demonstrators continue to take to the streets. Maduro has presided over the collapse of Venezuela’s economy. More than 7 million people have fled that country.
