A week after Azealia Banks called for Sarah Palin to be raped by a group of black men, the rapper set her sights on a new target: Twitter CEO Jack Dorsey.

In a series of tweets on Wednesday, Banks alleged that Dorsey backed out of a deal in which he would tweet about her latest album in exchange for her promotion of Square Cash, a money transfer service from Dorsey-owned company Square.

The outspoken rapper caused a firestorm last week when she tweeted a series of since-deleted messages that suggested that Sarah Palin should be forced to perform oral sex on a group of black men, and that the incident be filmed and uploaded to WorldStarHipHop.

Banks issued a semi-apology to Palin before lashing out again at Palin, saying the former Alaska governor and GOP presidential frontrunner Donald Trump represent “that contempt that whitey shares for this intangible, uncontrollable new black mind that’s been steeping for a while now.”

The rapper’s incendiary demands drew sharp rebuke from Palin, who later vowed to sue in order to “put the fear of God” in Banks and hold her accountable for her threats.

Dorsey and Palin aren’t the only ones Banks has tangled with on social media recently. The rapper also feuded with fellow rapper Wale and R&B star Erykah Badu this week. Later on Wednesday night, she took some shots at Kanye West:
