In Roseanne Barr’s first TV interview since her ABC sitcom was cancelled after a racist tweet, the comedian apologised for her “ill-worded” post and insisted she wasn’t racist.

During her hour-long interview with Sean Hannity on Fox News on Thursday night, Barr lamented the damage done to her by her tweet about Valerie Jarrett, a former adviser to President Barack Obama. “It cost me everything,” Barr said. “I wish I worded it better.”

Hannity repeatedly urged Barr to apologise to Jarrett on air. The comedian eventually did, saying she was sorry for the poorly worded tweet. She said she would tell Jarrett: “I’m sorry that you feel harm and hurt, I never meant that. I never meant to hurt anybody.”

She repeated her assertion that she did not know Jarrett was black when she likened Jarrett to a cross between the Muslim Brotherhood and a Planet of the Apes actor.

Barr repeatedly said on Thursday her tweet was meant to address US-Middle Eastern policy and had no racial overtones. She said she was stunned by the negative reaction, which Hannity noted was nearly universal.

“I am a creative genius, and this is not a good feeling for an artist to be treated this way, and it’s not a good feeling for a citizen, either.”

Despite apologising at times, Barr also said she felt the tweet was being mischaracterised and she indicated she felt like she had apologised enough for her actions.

“I feel like I have apologised and explained and asked for forgiveness and made recompense,” she said early in the interview. At another point, just before addressing Jarrett directly, Barr said: “I already have said I’m sorry for two months.”

Barr, a supporter of Donald Trump, brought him briefly into the conversation. “I’m not a racist and the people who voted for Trump, they’re not racist either, and Trump isn’t a racist, sorry. We just have a different opinion,” she said.

She said she could have fought ABC over her firing, but that she walked away from her hit reboot because she didn’t want anybody to lose their jobs. She said her contract was supposed to allow her to correct any misstatements she made within 24 hours, but she wasn’t given the opportunity.

ABC has announced it would produce a Roseanne spinoff called The Conners that features John Goodman, Laurie Metcalf and Sara Gilbert.
