Nazi concentration camp badge
In June 2020, Donald Trump was running for re-election. His campaign posted an advertisement on Facebook which said that "Dangerous MOBS of far-left groups are running through our streets and causing absolute mayhem." The ads identified these groups as "ANTIFA" and used an image of a downward-pointing red triangle. These ads appeared on the Facebook pages of Donald Trump, the Trump campaign, and Vice President Mike Pence. Many observers compared the graphic to the symbol used by the Nazis for identifying political prisoners such as communists, social democrats and socialists.  Many noted that there were 88 ads. Neo-Nazis use the number 88 as an abbreviation for the Nazi salute Heil Hitler. (The letter H is the eighth in the alphabet, so 88 stands for "HH.")
