Rosie O'Donnell: Trump's campaign is a 'nightmare'

Rosie O'Donnell's ongoing public feud with Donald Trump may be reignited again after the actress and comedian's blunt comments Wednesday about the billionaire mogul's presidential campaign.

"It's a nightmare," O'Donnell told the Associated Press. She wouldn't elaborate except for simply stating, "That's my quote."

Trump and O'Donnell's mutual disdain for each other can be traced back to 2006, when Trump, who currently leads the Washington Examiner's presidential power rankings, was still a co-owner of the Miss USA pageant. O'Donnell, at the time a co-host on "The View," criticized Trump for not firing Miss USA winner Tara Connor after allegations over her drug use, underage drinking and sexual activities.

O'Donnell got personal, slamming Trump's marriage history and calling his character into question.
