Donald Trump defended his attacks against "The View" co-host Rosie O'Donnell saying "Rosie is a bully — what she said was a lie."

"She said I went bankrupt — I never went bankrupt," Trump told O'Reilly at his talk show, "She's allowed to make fun of the hair, but I shouldn't be doing that [making fun of her looks]."

Earlier this week, Donald Trump re-fuelled his longtime feud with Rosie O'Donnell, calling her a "despicable person" who might be "jealous that Miss USA likes me and doesn't like her."

"Rosie's a loser, and somebody has to fight back," Trump told FOX News. "I really like Barbara Walters. Believe me — Barbara Walters, in my opinion, rues the day that she put that animal on her show because that show will go down the tubes. You watch."

The harsh comments came after Rosie O'Donnell, openly homosexual TV host and comedian (comedienne?), said about Donald Trump: "Left the first wife, had an affair, left the second wife, had an affair. Had kids both times, but he's the moral compass for 20-year-olds in America."

Obviously innerved by the Rosie's "humor", Donald Trump thinks this time it's serious.

"Rosie attacks me personally? I know her fairly well because her show failed. She didn't retire. She didn't get the ratings! Her magazine called 'Rosie was a total disaster," Donald Trump, whome Rosie named "someone with a comb-over", said.

"She's out of her mind. I will probably sue Rosie for a number of reasons. I'm worth a lot of money. She doesn't tell the facts," he added.
