Roseanne Barr apologizes for calling Obama aide a mix of 'Muslim Brotherhood and Planet of the Apes'

Roseanne Barr is issuing a mea culpa -- but is it genuine? Twitter is certainly skeptical.

Late Monday night, the "Roseanne" star tweeted a racially-charged insult about former Obama aide Valerie Jarrett, and it appears that now that the sun's risen, she's had a sudden change of heart.

In her original tweet, Barr likened Jarrett to a baby conceived between "Muslim Brotherhood and Planet of the Apes." This morning, she continued to double down after many called the tweet racist: "Islam is not a race, lefties," she tweeted just before 10 AM. "Islam includes every race of people."

Less than 20 minutes later, she began to backtrack on her statements: "I apologize. I am now leaving Twitter," she said.

That apology apparently wasn't sufficient on its own, because a few minutes later, she added, "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."

Many users in response expressed doubt that the sentiment was legitimate. "Hey ABC, forcing her to apologize will not make this go away," one wrote.

Barr did not address other controversial claims she's shared within the last 24 hours. She publicly accused Chelsea Clinton of being married to George Soros' nephew. Soros, a Jewish Hungarian philanthropist and business magnate, is a popular subject within right-wing conspiracy circles.

Clinton is in fact married to Marc Mezvinsky, who has no relation to Soros.
