Billionaire hedge fund manager Leon Cooperman says Sen. Elizabeth Warren "represents the worst in politicians," and that "she doesn't know who the fuck she's tweeting" after the Massachusetts Democrat's latest salvo against the rich.

A new ad by Warren, titled "Elizabeth Warren Stands Up to Billionaires," targets Cooperman, along with former CEO of TD Ameritrade Joe Ricketts, former Goldman Sachs CEO Lloyd Blankfein and Silicon Valley investor Peter Thiel according to CNBC.

In it, Cooperman - who joked in September that "they won't open the stock market if Elizabeth Warren is the next president - has the words "CHARGED WITH INSIDER TRADING" superimposed over his face.

"As far as the accusations of insider trading, I won the case. She’s disgraceful. She doesn’t know who the f--- she’s tweeting. I gave away more in the year than she has in her whole f----ing lifetime," Cooperman told CNBC on Wednesday.

Days before breaking out in tears on CNBC over the American political divide, sent Warren a Halloween letter in which he said she's treating him like "a parent chiding an ungrateful child."

Warren hit back, tweeting "Leon is wrong. I'm fighting for big changes like universal child care, investing in public schools, and free public college."

Leon is wrong. I'm fighting for big changes like universal child care, investing in public schools, and free public college.

Other business titans, including J.P. Morgan CEO Jamie Dimon, have taken on Warren for her attacks on the wealthy. Her war with business leaders has led to her crafting a strong group of supporters that have propelled her in the polls. After being behind the Democratic front-runner, former Vice President Joe Biden, by at least 30 points in May, she has surged to being only six points from catching up to his lead, according to a Real Clear Politics polling average. -CNBC

Interestingly, Warren's poll numbers started tanking after Warren unveiled her wealth tax plan and cooperman said "Her policies are counter-productive, they're negative for capitalism...you don't make the poor people rich by making the rich people poor."
