You stay classy, Sherrod Brown.

(The Hill) — Sen. Sherrod Brown (D-Ohio) took to the Senate floor Thursday to defend labor unions, saying that dictators like Adolf Hitler and Joseph Stalin opposed them.

Brown said that unions have wrongly come under attack from Republicans and conservatives, who are pitting workers against one another in states like his, where governments are taking action on anti-union legislation. Though he said he was not making a direct comparison, Brown claimed that “some of the worst governments we’ve ever had” have opposed labor unions.

“As a nation, I look back in history and some of the worst governments we’ve ever had, you know one of the the first thing they did? They went after the trade unions,” he said. “Hitler didn’t want unions, Stalin didn’t want unions. [Former Egyptian President Hosni] Mubarak didn’t want independent unions.”

Rhetoric over anti-union bills in Wisconsin and Ohio has reached a fever pitch, and politicians in Washington have adopted the cause to make political points.
