WATCH: Senator John Kennedy slams Biden for selling out US, destroys ‘Flip-Flop Fauci’

Kennedy talked on some of Biden's picks for his policy makers, calling them "the most radical folks I've ever seen."

"And I’m not, I’m not saying, you know, just a reasonable disagreement. These are people that that have contempt for America," said Kennedy. "They have contempt for Americans. They think they’re smarter and more virtuous than the American people who didn’t vote for President Biden in their opinion."

Kennedy also discussed the controversial nominee to head the Bureau of Alcohol, Tobacco, and Firearms, who earlier this week stated that he wants to ban AR-15s.

"And his nominee to the ATF. His copy of the Bill of Rights goes from amendment one to amendment three," Kennedy stated. "I’m convinced he doesn’t believe in the Second Amendment. Now this is America, you don’t believe what you want. But you can’t ignore the Constitution when you take an oath of office to abide by."

Hannity then asked Kennedy about "flip-flop Fauci," and recent developments in the lab leak theory gaining traction.

"Well, we’ll know and I’m going to say a word about Dr. Fauci. I know Dr. Fauci. I respect Dr. Fauci. I’m disappointed in Dr. Fauci. On too many issues, he has flip flopped, like a banked catfish," said Kennedy. "On too many other issues, Sean, you know, I’m a simple guy. I like breakfast food and straight answers, and he won’t give a straight answer. He dodges, bobs, weaves, rope-a-dopes. This is serious business. This is not some academic frolic. People’s lives and livelihoods are at stake."

"Now, his agency, he gave money to the Wuhan lab that was playing around with this virus. He needs to tell us everything he knows about that. What did they use the money for? What could they have used the money for?" Kennedy continued. "He says they didn’t do gain of function research. Gain of function just means they might have turned a benign harmless virus into a killer. And he said, well, they didn’t use my money to do that."

Hannity asked Kennedy about the recently revealed emails which showed that Joe Biden had previously met with Hunter Biden's foreign business partners at a dinner in DC, despite previously stating he had no knowledge on his son's dealings.

"Joe Biden denied any knowledge of Hunter’s foreign dealings, business dealings. We now know he lied, Senator, what should the consequences be?" Hannity asked.

"Well, President Biden needs to address this issue. President Obama put him in charge of the Foreign Affairs of two countries, China and Ukraine," said Kennedy. "And in both cases, his son walked away with millions of dollars worth of contracts. You know the message that sends to the world? American foreign policy can be bought, like a sack of potatoes. And President Biden needs to hit this one to head-on."
