Donald Trump has long used the term “Pocohontas” as a way to mock Elizabeth Warren. Saturday, he took his “joke” even further by ridiculing the “Trail of Tears,” the forced relocation of Native Americans in the 1830’s. The New Republic’s Jeet Heer remarked, “The joke here is that the Trail of Tears was a genocide. Get it? Get it?”

Of course as usual Trump has his band of defenders, but ignorance is never a good excuse.
