when was roseanne barr fired from the conners

Roseanne Barr was fired from "The Conners" in May 2018. Specifically, she was terminated after posting a racist tweet about Valerie Jarrett, a former advisor to President Obama, on May 29, 2018. This led ABC to cancel the "Roseanne" revival and subsequently create the spinoff "The Conners" without her involvement.
