Trump is like Harry Potter's Lord Voldemort, says Rosie O'Donnell

Fox News' Megyn Kelly is a "superhero," while her nemesis and Republican frontrunner Donald Trump is the evil Lord Voldemort from the Harry Potter movies, Trump's other nemesis Rosie O'Donnell said in a radio interview airing Sunday night.

O'Donnell (no relation to this reporter) has had a long-running battle with Trump that peaked during the August Republican debate when Kelly asked him about some of his most vulgar references to certain women and their looks, including that they are dogs and pigs.Trump quickly responded that he only refers to O'Donnell that way.

Last week, Kelly — who Trump has called crazy and highly overrated — met with the Republican frontrunner to "clear the air" and discuss a possible interview, Kelly said.

In an interview with Rita Cosby on the New York City radio station WABC set to Sunday night at 7 p.m. ET, O'Donnell took the scary movie themes further.

"I think it's an epic battle worthy of a new Star Wars movie," said O'Donnell. "You have to decide. Are you going to be with the force or are you going to be on the dark side? It's your choice."

O'Donnell is a supporter of Hillary Clinton, who she says is "a source of light and inspiration." Of Trump, O'Donnell urged listeners to "stay away from the dementor."

"He's not even qualified to run a game show," she said of Trump. "He is the worst representation of what the United States is or could be."
