Democratic presidential nominee Joe Biden on Saturday compared President Trump to the architect of the Nazi propaganda machine.

“He’s sort of like [Joseph] Goebbels,” Biden told MSNBC's Stephanie Ruhle. “You say the lie long enough, keep repeating it, repeating it, repeating it, it becomes common knowledge.”

The comment comes as Biden has pushed back against attacks on the campaign trail from the president, who is looking to paint the former vice president as a socialist.

Biden has pushed back against the socialist comparison, arguing it's Trump's way of spreading false information in an effort to appeal to moderate voters, especially in the battleground state of Florida. He also said the effort is to distract from his handling of the coronavirus pandemic, which has infected more than 7 million people in the U.S. and killed more than 204,000, according to the latest update by Johns Hopkins University.

“It's always about distraction with him,” Biden said. “It's going to be clear from the beginning exactly where this is going.”

Goebbels was the minister of propaganda for Adolf Hitler's Third Reich, and used a technique that Hitler coined the “Big Lie,” which involved repeating a major falsehood until the public came to believe it was true.

Matt Brooks, the executive director of the Republican Jewish Coalition, slammed Biden's comparison in a statement, urging the former vice president to apologize and retract the "egregious comment."

"Instead of engaging in a debate on policy, Joe Biden has descended to name-calling and Holocaust references," Brooks said. "There is no place in political discourse for Holocaust imagery or comparing candidates to Nazis. It’s offensive and it demeans the memory of the Holocaust, the suffering of the victims, and the lessons we must learn from that terribly dark chapter of history."

Biden also slammed the president's response to growing civil unrest, citing his decision to disperse protesters in Washington, D.C., to visit St. John's Church in June.

“I think people see very clearly the difference between me and Donald Trump,” Biden said. “Trump is clearing protests in front of the White House that are peaceful, you know, with the military. This guy is more Castro than Churchill.”

A spokesperson for the Trump campaign did not immediately return Fox News' request for comment.
