why was roseanne fired from the conners

Roseanne Barr was fired from the show "The Conners" because of a series of racist tweets she posted about Valerie Jarrett, a former advisor to President Barack Obama. The tweets were widely condemned as offensive and racist, prompting ABC to cancel the revival of the original "Roseanne" series where she was the star. Following her firing, the show was retooled as a spinoff titled "The Conners," which continued without the character Roseanne, who was written off as having died from an opioid overdose. ABC's decision was described as necessary due to the nature of her comments being "abhorrent, repugnant, and inconsistent with our values." This led to a permanent severing of ties between Roseanne Barr and the network, with no indication of her potential return to the show.
