Donald Trump and Rosie O'Donnell, two media personalities who have never kept their mutual loathing for one another a secret, are in the midst of an explosive Twitter feud.
O'Donnell revisited her feelings towards the "Celebrity Apprentice" host when she joined the chorus of critics who bashed Trump for deciding to moderate a GOP debate. O'Donnell compared him to Lord Voldemort on Joy Behar's HLN show last week.
Trump took to YouTube on Wednesday to criticize O'Donnell's new show on the Oprah Winfrey Network (OWN). Trump called O'Donnell's show a "complete and total disaster." He also attacked MSNBC's Lawrence O'Donnell and said that his show was "failing." Trump then tweeted the video, with the message "#trumpvlog Same last name, same bad ratings- @lawrence and @rosie....."
O'Donnell tweeted back and attacked Trump's self-proclaimed wealth. "How many billionaires sell ties and have crappy non reality shows - none - go back to selling snake oil - #bankruptmuch?" O'Donnell tweeted.
Trump and O'Donnell went back-and-forth in a heated Twitter clash throughout Wednesday morning. Trump tweeted that he felt bad for O'Donnell's fiancé Michelle Rounds, and called O'Donnell a "true loser." O'Donnell responded by calling Trump "an ass."
