The version played included the first stanza, beginning "Deutschland, Deutschland uber alles, uber alles in der Welt" which was used as Nazi propaganda.

It translates as "Germany, Germany, above all, above all in the world" and was dropped after World War Two because of its association with Adolf Hitler

I guess the USTA thought if America First is good enough for Trump in 2017 in his inauguration speech, it would be only fair to give Germany the same treatment. I mean America First was also associated with the US Nazi sympathizers in the 1930's..
