It was one of the most spectacular resignations in corporate America.
Goldman Sachs employee Greg Smith quit his firm in a very public way after 12 years with the company: He did it with a scathing op-ed published in "The New York Times."
Now, Smith has expanded his public resignation letter into a book, called "Why I Left Goldman Sachs," which releases today.
William Cohan, author of "Money and Power: How Goldman Sachs came to rule the world," talks with John and Zoraida on "Early Start." Cohan, who worked on Wall Street as an investment banker for almost 20 years, weighs in on Smith's claims of the company's operating culture.
