Washington (CNN) President Donald Trump's eldest son said the platform of the Democratic Party is similar to that of the Nazi Party in Germany during the early 1930s and that history classes are biased against conservatives.

In a video posted Thursday by the pro-Trump One America News Network , Jack Posobiec -- a prominent right-wing voice online who supported the Pizzagate hoax -- spoke with Donald Trump Jr., who compared the present-day Democratic Party to Nazis and disparaged history taught by academics.

"I've been out hearing the left talking about all these things, fascism, Nazism on the right," Trump Jr. said. "And when you look at the actual history of how these things evolved, and when you actually look at that platform versus the platform of the modern left, you say wait a minute, those two are really heavily aligned and, frankly, contrary to the right."

He warned people against saying something "because someone told you that in a history class" because academia had been influenced by the left.

"You see the Nazi platform in the early 1930s and what was actually put out there ... and you look at it compared to like the DNC platform of today, and you're saying, man, those things are awfully similar, to a point where it's actually scary," Trump Jr. said.
