ABC has cancelled its hit reboot of "Roseanne" following her racist tweet about former Obama adviser Valerie Jarrett.
In her tweet, Barr suggested that former White House adviser Valerie Jarrett is a product of the Muslim Brotherhood and the "Planet of the Apes."
The TV star deleted the tweet subsequently and tweeted to Jarrett that she was sorry "for making a bad joke" about her politics and her looks. Jarrett, who is African-American, advised Barack and Michelle Obama.
