Asked for her opinion on the presidential campaign of her longtime adversary Donald Trump, Rosie O’Donnell called it a “nightmare.”

The AP reports that O’Donnell kept her response succinct, saying simply: “It’s a nightmare. That’s my quote.” The quote arose during an interview O’Donnell gave about her upcoming appearance on Fox’s “Empire.”

EW.com notes that Trump alluded to his long-running beef with O’Donnell during the Fox News GOP debate in August when he was challenged by moderator Megyn Kelly for allegedly using his Twitter account to call women “fat pigs, dogs, slobs, disgusting animals.”

Trump responded: “Only Rosie O’Donnell.” The AP notes that Kelly then corrected him. Following the debate, Trump spent several weeks repeatedly going after Kelly.

The Trump-O’Donnell beef has been going on at least since 2006, EW notes, when O’Donnell called Trump a “snake-oil salesman” on “The View.” Trump responded by calling O’Donnell “a real loser” and “a woman out of control.”
