Leave it to Donald Trump to rub salt in Rosie O'Donnell's wounds.
The Donald couldn't help but hide his glee over the news that O'Donnell's talk show has been cancelled by Oprah Winfrey's cable network. He tweeted Monday, "Rosie O'Donnell has failed again. Her ratings were abysmal and Oprah cancelled her on Friday night. When will media executives learn that Rosie just hasn't got it."
Trump and O'Donnell have had a longstanding feud that began in 2006, when she criticized the billionaire and "Celebrity Apprentice" honcho for not firing then-Miss USA Tara Conner, who was embroiled in scandal at the time. Trump owns the Miss USA pageant.
