Washington (CNN) A Republican congressman quoted from Adolf Hitler's "Mein Kampf" to accuse Democrats and the news media of pushing a "big lie" over the special counsel investigation.

"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," Rep. Mo Brooks, an Alabama Republican, said on Monday.

The congressman's speech came after special counsel Robert Mueller notified the Justice Department last week that he has concluded his investigation into Russian interference in the 2016 election. On Monday, Brooks said that the accusations of collusion between Trump's campaign and Russia are "nothing but a 'big lie.'"

"In that vein, I quote from another socialist who mastered 'big lie' propaganda to maximum, and deadly, effect," Brooks said on the House floor Monday.

"Quote, 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; and thus, in the primitive simplicity of their minds, they more readily fall victims to the big lie than the small lie," Brooks said, quoting from James Murphy's English translation of Hitler's "Mein Kampf."
