Facing criticism for repeatedly harnessing rhetoric once used by Adolf Hitler to argue that immigrants entering the U.S. illegally are “poisoning the blood of our country,” Trump insisted he had no idea that one of the world’s most reviled and infamous figures once used similar words. The Nazi dictator spoke of impure Jewish blood “poisoning” Aryan German blood to dehumanize Jews and justify the systemic murder of millions during the Holocaust.
“I know nothing about Hitler,” he insisted. “I have no idea what Hitler said other than (what) I’ve seen on the news. And that’s a very, entirely different thing than what I’m saying.”
Trump’s assertion that he knows so little about one of the 20th century’s most documented figures is notable for someone seeking the presidency, a role steeped in and shaped by history. But claiming ignorance, particularly when it comes to people who espouse racist or antisemitic rhetoric, is a tactic Trump has repeatedly deployed when aiming to distance himself from uncomfortable storylines.
After he was endorsed by former Ku Klux Klan grand wizard David Duke during his winning 2016 campaign, Trump insisted he had no knowledge of the white supremacist who had run for office numerous times and is described by the Anti-Defamation League as “perhaps America’s most well-known racist and anti-Semite.”
“Just so you understand, I don’t know anything about David Duke, OK?” he told CNN’s Jake Tapper in February 2016. “I don’t know anything about what you’re even talking about with white supremacy or white supremacists.”
