After it was revealed that her approval ratings have plummeted to record lows this week, Kamala Harris was hit with yet another crushing blow when former Speaker of the House Newt Gingrich branded her as “the worst vice president in American history.”

“I think she actually accomplished something very historic,” Gingrich told Fox News host Sean Hannity. “She got CNN, historically the strongest supporter of liberal Democrats, to run an entire story pointing out that the president’s team and the vice president’s team are fighting internally, in a very ferocious way. I’ve never seen CNN do anything that would be harmful to Joe Biden.”

“This story was devastating, and I think it starts with a simple fact. Biden’s at 38 percent approval. She’s at 28% approval. Powerful people wake up in the morning,” he added. “They go, ‘It can’t be me. So I wonder who’s doing this?’ So the Biden people say it’s all Harris’s fault. The Harris people say, you know, if only he was using her correctly.”

Not stopping there, Gingrich proceeded to double down by calling Harris “an embarrassment.”

“I think you’re going to see more of this kind of backbiting because the truth is she hasn’t accomplished anything. I mean, it’s an embarrassment. But then, on the other hand, she’s working with Joe Biden, who has accomplished almost nothing. And it’s an embarrassment.”

“As you point out, just watching him in public in an unscripted environment is a little frightening, frankly, to think that this is the commander-in-chief and to know that our opponents around the planet are watching the same TV coverage,” he concluded. “I think this is, having known a fair number of vice presidents, this is an amazing moment for probably the worst vice president in American history.”

Gingrich also went after Harris in another blistering interview this week in which he criticized her and Joe Biden for trying to appear united in front of the cameras.

“When I watched Harris and Biden coming out yesterday hand in hand, I was reminded instantly of Gary Cooper and Audrey Hepburn in Love in the Afternoon — a total failure of a movie because Cooper is way too old for Hepburn,” he said Tuesday, according to The Washington Examiner.

Gingrich then called out what he sees as their “phony” relationship for the camera as the two went before the press to sign the $1 trillion legislation funding transportation and broadband networks.

“I thought to myself, having our esteemed vice president who wasn’t even laughing — it was an amazing, magic moment. … She was cheerful and happy, but not laughing, and she was there with our modern Gary Cooper in the form of the president,” he told WMAL. “They were proving to us how happy they are to be together by being totally phony. It was one of those great, magic moments in Washington history where phoniness won out.”
