A spectator at the US Open was kicked out after chanting what used to be the lyrics of the German national anthem, but is now a reminder of the country's Nazi past. Here's what you need to know about the anthem.
A fan was ejected from a U.S. Open tennis match early Tuesday morning after German player Alexander Zverev complained the man made comments about Adolf Hitler.
Created in the 19th century, the "Deutschlandlied" was sullied by the Nazis. Germany decided 70 years ago that it would keep its third verse as its national anthem.
