Wanda Sykes announced Tuesday on Twitter that she will not return to ABC's revival of "Roseanne" after the show's star Roseanne Barr compared Valerie Jarrett, an African-American former adviser to then-President Barack Obama, to the film "Planet of the Apes."

"I will not be returning to @RoseanneOnABC," Sykes tweeted. The comedian was a head writer for "Roseanne," which returned for a tenth season in March.

Barr was met with criticism after she likened Jarrett, who is African-American, to the Muslim Brotherhood, a conservative organization in Egypt, and the film "Planet of the Apes."

"Muslim brotherhood & planet of the apes had a baby=vj," Barr wrote in response to a comment about Jarrett on Twitter.

Barr then apologized for the statement and said she was leaving Twitter. ABC has yet to comment on the incident.

"I apologize. I am now leaving Twitter," she said.

"I apologize to Valerie Jarrett and to all Americans. 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," Barr continued.

"Roseanne" was renewed for an 11th season in March.
