Roseanne Barr returned to Twitter early Wednesday morning after having initially told the general public that she would be removing herself from the social media platform. The actress, whose ABC sitcom was cancelled as a result of a racist tweet controversy, offered some extra apologies and provided some supplementary excuses for her abhorrent behaviour. 

After having called Obama's former senior adviser Valerie Jarrett the child of an ape and a member of the Muslim Brotherhood, Barr admits that had some very uninformed opinions about the politician and her cultural heritage. Replying to one of her fans, she admits "I honestly thought she was Jewish and Persian-ignorant of me for sure, but...i did."

Shortly afterwards, Barr began to cite the prescription drug Ambien as a catalyst for her outburst. In a since-deleted series of tweets, she reveals  "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." Barr followed that up with "not giving excuses for what I did(tweeted) but I've done weird stuff while on ambien -- cracked eggs on the wall at 2am etc."

Another of Barr's deleted tweets saw the disgraced sitcom star proclaim "I'm sorry 4 my tweet, AND I will also defend myself as well as talk to my followers. so, go away if u don't like it. I will handle my sadness the way I want to. I'm tired of being attacked & belittled more than other comedians who have said worse."

Barr has effectively created the largest social media blunder in recent memory.
