Comedian uses racially charged joke about African American Obama adviser

Roseanne Barr waded into racial waters on Monday, suggesting that former Barack Obama adviser Valerie Jarrett is a product of the Muslim Brotherhood and the "Planet of the Apes."

"muslim brotherhood & planet of the apes had a baby=vj," Barr tweeted in response to a post about Jarrett.

Jarrett, who is African-American with no ties to the Sunni Muslim organization known as the Muslim Brotherhood, was one of most senior and long-term presences in the Obama White House and a lightning rod for right-wing critics.
