CNN hosts were angry and frustrated at "Jeopardy!" contestants who didn't know the name of President Joe Biden's nominee to the U.S. Supreme Court.

The clip came from the November 9 broadcast of the game show.

"She's the first black woman on the Supreme Court and the first justice to have been a federal public defender," was the clue, but none of the contestants even ventured a guess.

The answer, of course, was Justice Ketanji Brown Jackson.

Don Lemon took his glasses off and sighed dramatically after CNN rolled the clip.

"I don't think that's surprising, I will say," said co-host Kaitlan Collins.

"But these are smart people in the world," responded Lemon.

"That's a good point," said Collins.

"When you go on Jeopardy," Lemon said.

"She was just confirmed, it's been in the news!" Poppy Harlow interjected.

"If you're standing outside, I think Kaitlin's right, if you're standing outside of a mall or whatever, people may not know, when they do the man on the street thing, yes," Lemon said.

"But when you're smart enough to be a contestant on ‘Jeopardy!’?" he questioned.

"You gotta know about current events!" said Collins.

"Yeah!" Lemon agreed.

"And history-making ones," added Harlow.

"Yeah!" Lemon said. "Yeah!"

Jackson was confirmed by the U.S. Senate by a vote of 53 to 47 in April with three Republican senators breaking ranks and joining with Democrats. She replaced Justice Stephen Breyer, who retired from the court.

"Judge Jackson’s confirmation was a historic moment for our nation. We’ve taken another step toward making our highest court reflect the diversity of America," said Biden at the time.

Some viewers also excoriated the celebrity edition of "Jeopardy!" after a clue on the show referenced the suicide death of Brian Laundrie, who admitted to killing his fiancée, Gabby Petito, in a crime that made national headlines.
