Former President Donald Trump reupped his hateful rhetoric about immigrants in two campaign stops over the weekend, twice saying that immigrants were “poisoning the blood of our country.” A similar version of the phrase appears in Adolf Hitler’s manifesto Mein Kampf, a book that some doubt Trump has read. However, in a 1990 interview with Vanity Fair, Trump’s first ex-wife Ivana Trump said the future president kept a collection of Hitler’s speeches in their bedroom.
