Sen. David Perdue, R-Ga., on Wednesday excoriated Democrats on the Senate floor by saying they were employing tactics used by the Nazis nearly 100 years ago to get Republicans to back down from the nomination of Brett Kavanaugh to the Supreme Court.

Perdue and his wife were accosted by protesters as they arrived in Washington this week, a step he said showed that Democrats and their activist allies are going "too far."

"I believe my Democratic colleagues have gone one tick too far this time," he said. "When paid activists who support you attack my wife, you have gone too far."

Perdue noted that several Democrats have said Republicans should be confronted in public over Kavanaugh, which he said is a tactic used by the Nazi Brownshirts who intimidated and used violence against Jews in order to aid Hitler's rise to power.

"This is America. But these are the tactics of the Brownshirts in Germany in the 1930s," he said. "Unacceptable."

He said one House Democrat has talked about not letting Republicans eat in public in peace without being harassed about Kavanaugh.

"You are inciting this disrespect of our law," he said of these tactics. "One of my Democratic colleagues in this body has encouraged people to, and I quote, 'get in the face of some of those congresspeople.' Really?"

Perdue said Democratic rhetoric about Kavanaugh in general has gone way over the top.

"One of my Democratic colleagues called Judge Kavanaugh your worst nightmare," he said. "Another called him a nominee who wants to pave the path of tyranny, Mr. President. Yet another said this Supreme Court confirmation would mean the destruction of the Constitution. Seriously."

Sen. Kamala Harris, D-Calif., made the comment about the Constitution being destroyed.

"That's irresponsible for somebody in this body," he said.

Sen. Cory Booker, D-N.J., has said anyone supporting Kavanaugh would be "complicit in his evil," another remark aimed at the unproven sexual assault allegations against the nominee.
