Trump refers to Secret Service as "S.S." in tweet

In a recent tweet, Trump thanked law enforcement agencies for their handling of "protesters, agitators, anarchists (ANTIFA), and others," referring to the Secret Service as "S.S.", an abbreviation used for the major paramilitary organization "Schutzstaffel" under Adolf Hitler and the Nazi Party in Nazi Germany.
The commonly used abbreviation for the Secret Service is USSS and has been used by Trump before. The Jewish Democratic Council of America responded, calling Trump the "biggest threat to American Jews" and writing "another dog whistle to white supremacists and neo-Nazis".
