"Roseanne" was canceled Tuesday following a racist tweet posted by star Roseanne Barr about former Obama aide Valerie Jarrett.

Barr tweeted that Jarrett, who is African-American and was born in Iran, is like the "muslim brotherhood & planet of the apes had a baby."

Barr later apologized and announced she was leaving Twitter.

A short time later, ABC Entertainment president Channing Dungey said in a statement that the network has decided to cancel the "Roseanne" reboot.

On "Outnumbered Overtime," Fox News contributor Jessica Tarlov said Barr's tweet was an example of "blatant racism."

"Roseanne Barr is a racist," Tarlov stated, pointing out that Barr has had a history of making anti-Semitic remarks on Twitter.

She noted that before the cancellation announcement, comedian and "Roseanne" consulting producer Wanda Sykes said she was leaving the show over Barr's racist remark.

"That's the importance of people standing up and saying, 'I will not participate in something that espouses those values and those views,'" Tarlov said.
