"A billionaire who calls women 'fat broads' and 'horse-faced lesbians!' And no, I'm not talking about Donald Trump, I'm talking about Mayor Bloomberg!" she added.
"Democrats are not going to win if we have a nominee who has a history of hiding his tax returns, of harassing women, and of supporting racist policies like red-lining and stop and frisk," she continued.
"Look, I'll support whoever the Democratic nominee is, but understand this, Democrats take a huge risk if we just substitute one arrogant billionaire for another," she concluded. "This country has worked for the rich for a long time and left everyone else in the dirt."
Bloomberg responded by reciting items from his resume and claiming he has the best chance to beat President Donald Trump.
"I'm a New Yorker, I know how to take on an arrogant con man like Donald Trump who comes from New York," said Bloomberg.
"I'm a mayor, or I was a mayor. I know how to run a complicated city, the biggest, more diverse city in this country," he added.
