Late-night talk show host Conan O'Brien on Tuesday joked about the news that Roseanne Barr's character will be dead in the upcoming "Roseanne" spinoff, "The Conners," following her firing by ABC earlier this year.

"Finally," O'Brien said, "a funeral Trump will be allowed to attend."

"It’s been reported that Trump's relationship with Sessions is 'beyond repair,'" O'Brien said. "Apparently, their relationship is so bad and awkward, Trump now refers to Sessions as 'Melania.'"

ABC's relaunch of "Roseanne," which revamped its titular character as a current-day Trump supporter, was canceled after Barr made racist comments about Valerie Jarrett, a former senior adviser to President Obama.

Barr in a tweet said Jarrett, a black woman, was the offspring of the Muslim brotherhood and apes.

In recent interviews, she has said she became a "hate magnet" after the comments. She has also said she did not know Jarrett was black, claiming, "I thought the bitch was white" in a video posted to her YouTube channel. 

Actor John Goodman said in an interview published Sunday that "The Conners," ABC's planned spinoff, will handle Barr's exit by killing off her character.

“She had to sign a paper saying that she relinquished all her rights to the show so that we could go on,” Goodman told The Times of London. “I sent her an email and thanked her for that. I did not hear anything back, but she was going through hell at the time. And she’s still going through hell.”
