Sen. John Kennedy John Neely KennedyMORE (R-La.) on Sunday blasted the theatrics and chaos surrounding Supreme Court nominee Brett Kavanaugh's confirmation process, and was critical of the timing of a recent disclosure of an anonymous sexual misconduct allegation against the judge.

"I'm fairly confident that our Founding Fathers did not intend the process to work this way. So far it's pretty much been an intergalactic freak show," Kennedy said on "Fox News Sunday."

"Sen. Grassley, our chairman, did the best he could at the hearing," he continued, referring to Senate Judiciary Committee Chairman Chuck Grassley Charles (Chuck) Ernest GrassleyThe Hill's 12:30 Report: Ginsburg lies in repose Top GOP senators say Hunter Biden's work 'cast a shadow' over Obama Ukraine policy Read: Senate GOP's controversial Biden report MORE (R-Iowa). "Senators kept interrupting him. They ignored the rules. We had over 240 protesters who stood up screaming. The only thing missing, I think, was the — the genitalia-shaped headgear."

"There were wild accusations about Kavanaugh that he's evil and he hates women, he hates children, he hates little warm puppies," he continued. "And now we have this recent allegation by Sen. Feinstein."

Kennedy was referencing a letter Sen.

The letter reportedly describes an incident in which Kavanaugh and a friend took a woman into a bedroom, where the door was locked and she was thrown onto the bed. The woman said Kavanaugh got on top of her and put a hand over her mouth. All three individuals were minors at the time of the alleged incident.

Kavanaugh said Friday that he “categorically and unequivocally” denied the allegation, which liberal outside groups opposed to the nominee say should block his confirmation.

A Feinstein spokesman said Friday that the senator wanted to make the information on Kavanaugh public, but the woman involved did not want it to be publicly disclosed. Feinstein received the information "through a third party," the spokesman said.

Kennedy and other Republicans have noted that the letter was sent in July, and that Democrats did not bring the issue to light during any closed-door hearings leading up to Kavanaugh's confirmation.

"Most Americans are looking at this — most mainstream Americans — and they're thinking that Congress has hit rock bottom and started to dig," Kennedy said Sunday. "And I have been embarrassed by the whole process."

"And, frankly, no disrespect to Sen. Feinstein or to Stanford Law School, but I'm a little bit offended," he continued. "I sit on Judiciary Committee. They've had this stuff for three months. If they were serious about it, they should have told us about it."
