Elizabeth Warren bought a television ad on CNBC (a popular business news channel) and called out some of the nation’s wealthiest for some of their gains.

The 70-year-old Warren appears to have them, as the youths say, shook. On Wednesday, one particular wealthy elite she called out, Leon Cooperman, called her disgraceful. And Lloyd Blankfein, former CEO of Goldman Sachs, on Thursday resorted to a racist attack over someone calling for him to pay more taxes.

“Surprised to be featured in Sen Warren’s campaign ad, given the many severe critics she has out there,” he wrote on Twitter. “Not my candidate, but we align on many issues. Vilification of people as a member of a group may be good for her campaign, not the country. Maybe tribalism is just in her DNA.”

Blankfein was called out in the ad for the $70 million he made during the financial crisis when his bank took $10 billion from the federal government.

His tweet is mocking Warren over her claims of Native American heritage, which she took a DNA test to prove, and which received much criticism. So did he in the aftermath of his tweet.

This is going to end with billionaires getting themselves added to civil rights law as a protected class https://t.co/h2gFkgMA3P — Irin Carmon (@irin) November 14, 2019

"Vilification of people as a member of a group" Ah yes, it's always good to implicitly compare a microscopically-tiny group of people who have hoarded wealth for their own personal gain to people who've been persecuted and killed just due to their race/ethnicity. — Pé Resists (@4everNeverTrump) November 14, 2019

Warren’s extreme wealth tax—which calls for two cents on every dollar past $50 million and three cents on every dollar past $1 billion—is nowhere remotely close to the much higher tax brackets the U.S. had on high earners decades ago.
