Comedian Roseanne Barr recently tweeted that Obama advisor Valerie Jarret, who is black, resembles the offspring of “muslim brotherhood and planet of the apes," Slate reports. Roseanne Barr then announced she was leaving Twitter, but she was back on it less than 12 hours later.

Roseanne tweeted again, "ABC has canceled my sitcom and I have nothing to lose." That, however, was only the beginning of the tweet blizzard, when she began retweeting her supporters' posts, then critics' commentary, then fans' tweets again.

In her maniac Twitter relaunch, Barr finally apologized to Valerie Jarrett:

"@ValerieJarrett I want to apologize to you. I am very sorry to have hurt you. I hope you can accept this sincere apology!"

"@ValerieJarrett i don't know if u saw it, but I wanted2 apologize to u 4 hurting and upsetting u with an insensitive & tasteless tweet. I am truly sorry-my whole life has been about fighting racism. I made a terrible mistake wh caused hundreds of ppl 2 lose their jobs. so sorry!

As reported by Slate, "after having spent a few hours retweeting people who defended her, Barr repeatedly asked her fans not to defend her, while suggesting her racist tweet was caused by Ambien

"hey guys, don't defend me, it's sweet of you 2 try, but...losing my show is 0 compared 2 being labelled a racist over one tweet-that I regret even more."

"guys I did something unforgiveable so do not defend me. It was 2 in the morning and I was ambien tweeting-it was memorial day too-i went 2 far & do not want it defended-it was egregious Indefensible. I made a mistake I wish I hadn't but...don't defend it please. ty"
