Billionaire hedge fund manager Leon Cooperman again unloaded on Sen. Elizabeth Warren in an interview Wednesday with CNBC, a month after sending her a five-page letter.

Why it matters: His comments came in response to Warren's latest TV ad, which is titled “Elizabeth Warren Stands Up to Billionaires,” and will begin running on the network soon.

“In my opinion she represents the worst in politicians as she’s trying to demonize wealthy people because there are more poor people than wealthy people,” Cooperman said.

“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.”
