US television host Jimmy Kimmel has weighed in on the Roseanne cancellation storm by calling for "compassion" for its troubled star.
ABC scrapped the massively popular sitcom on Tuesday after Barr tweeted that former Obama aide Valerie Jarrett was the baby of the Muslim Brotherhood and the "Planet of the Apes".
Barr has since deleted the tweet and apologised, saying: "I am truly sorry for making a bad joke about her politics and her looks. I should have known better. Forgive me-my joke was in bad taste."
Now, fellow ABC star Kimmel has taken to Twitter to share his thoughts on the controversy, tagging Barr in a tweet which read:
What @TheRealRoseanne said is indefensible, but angrily attacking a woman who is obviously not well does no good for anyone. Please take a breath and remember that mental health issues are real. The Roseanne I know could probably use some compassion and help right now.

It comes after Barr's co-star John Goodman - who served as her on-screen husband, Dan Conner, on the iconic show - said he would “rather say nothing than to cause more trouble”.
He added: "Everything's fine ... I wasn't gonna get an Emmy anyway."
Roseanne, which first aired in 1988, made a hugely successful comeback earlier this year - becoming one of the most watched sitcoms on American TV after more than two decades off the air.
Despite vowing to leave Twitter, Barr returned to social media after Tuesday's cancellation to describe her comments as "indefensible", before retweeting several statement in support of her.
She further apologised to those who had lost their jobs over the matter, including Goodman, but also condemned cast members who "threw me under the bus".
She tweeted on Wednesday: “I’m not a racist, I never was & I never will be.
“One stupid joke in a lifetime of fighting 4 civil rights 4 all minorities, against networks, studios, at the expense of my nervous system/family/wealth will NEVER be taken from me.”
It's little more than a year since Barr, 65, angered Twitter users this side of the Atlantic by claiming that the Irish were "occupying Ireland" in a similar manner to the situation between Israel and Palestine.
In March 2017, she tweeted: "The lefty Irish R up to their armpits in hosting anti semitic festivals abt killing all jews in Israel, but h8 me saying give Ireland away2".
She also wrote: "Give Ireland back to the British too."
