“ ‘A “big lie” is a political propaganda technique made famous by Germany’s National Socialist German Workers Party. ... For more than two years, socialist Democrats and their fake news media allies — CNN, MSNBC, the New York Times, Washington Post and countless others — have perpetrated the biggest political lie, con, scam and fraud in American history.’ ”

That’s Republican congressman Mo Brooks of Alabama lashing out at the left and the mainstream media for fanning the flames of the collusion allegations that have dogged President Donald Trump since he took office.

Brooks took a page from Adolf Hitler’s opus, “Mein Kampf,” to accuse the political left of propagating the “big lie,” an expression coined by the Führer to describe how Jews used a capacity for falsehoods to place blame for German World War I losses on a decorated but antisemitic commander.

Specifically, Brooks quoted the 10th chapter of the Hitler book, which was banned in Germany until 2015: "In the big lie, there is always a certain force of credibility because the broad masses of a nation are always more easily corrupted in the deeper strata of their emotional nature than consciously or voluntarily,” he said.

Watch Brooks’s speech:

The Washington Post pointed out Brooks ultimately inverted his analogy, making Democrats the equivalent of German and Austrian Jews. “He set out to compare the other side to fascists, but he was the one employing a fascist smear — one that, ironically, came to define Nazi propaganda,” the Post’s Isaac Stanley-Becker explained.

Brooks’s fellow House Republican, Louie Gohmert of Texas, took a turn a day later, seeking on Tuesday to, like Brooks before him, depict Hitler’s animating political philosophy as socialist because his far-right party’s name, Nationalsozialistische Deutsche Arbeiterpartei, includes the German-language adjective for socialist.

Gohmert, in a House Judiciary Committee discussion about compelling the Justice Department to turn over information from Special Counsel Robert Mueller’s probe as to whether the Trump White House obstructed justice, expressed a fear that an unshackled Justice Department in the hands of authoritarian — “it won’t be Trump,” he averred — could pave the way for “another socialist like Hitler to come along.”

Apprised by Reps. Steve Cohen, a Tennessee Democrat, and David Cicilline, a Rhode Island Democrat, that, their formal name notwithstanding, Nazis were not socialists, Gohmert appeared nonplussed.

Allowing that Gohmert’s remark “might have been a little error on your part,” Cohen elaborated that it was “as a Jewish person” that he took offense to Gohmert’s equating of the horrors of Nazism with an economy-organizing principle.

“Reclaiming my time,” Gohmert interjected, “they were the National Socialist Party. ... It’s what they were, and I’m sorry. We need to do whatever we can to avoid another Holocaust. And I’m sorry [Cohen] was offended by the term.”

“They weren’t socialist,” Cicilline heatedly responded. “They were fascists.”

Gohmert, unbowed, insisted: “They claimed to be socialist, and they were.”
