Sen. Elizabeth Warren's (D-Mass.) latest shot at billionaires has one one-percenter ready to blow.Warren, a 2020 frontrunner, has compiled some billionaires' angry reactions to her proposed "wealth tax" into a new ad set to premiere on CNBC this week. One of those unhappy rich guys is Leon Cooperman, and after seeing Warren's ad, tossed a few f-bombs her way in protest.Warren's proposed wealth tax would have the nation's wealthiest people handing more money to the federal government after her election. According to her website's calculator, that would be $151 million for Cooperman next year, out of his $3.2 billion net worth. "You'll still be extraordinarily rich," Warren's website truthfully tells Cooperman, but he has still said Warren's "vilification of billionaires makes no sense to me. It's bull."A clip of Cooperman saying that appears in Warren's ad, followed by a reminder that he was "charged with insider trading." And after Cooperman saw that, he decided to call Warren "disgraceful" in an interview with CNBC. "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 continued. Cooperman also said he "won" his case involving insider trading, though he actually just settled it with the Securities and Exchange Commission.Upon seeing Cooperman's response, Warren's chief strategist Joe Rospars had just one question.
