Rosie O'Donnell isn't mincing words when it comes to Donald Trump's presidential campaign. O'Donnell, a former co-host of The View, was asked about Trump on Monday while discussing a guest starring role on Wednesday's episode of Fox's drama series Empire. She said of Trump's campaign, "It's a nightmare. That's my quote." The animosity between Trump and O'Donnell dates back years. In 2006, O'Donnell criticized him for remarks he made about a winner of his Miss USA beauty pageant, saying he had no right to be a "moral compass" for the beauty queen. That unleashed a series of barbs from Trump, who called O'Donnell a "loser" and "slob," among other insults. In turn, O'Donnell questioned his business skills and hairstyle and compared him to a "snake oil salesman."
