William D. Cohan, a former senior Wall Street investment banker, tells the inside story of JPMorgan Chase’s landmark mortgage settlement—the largest financial settlement of all time until last week. He probes into the unfiled civil complaint of U.S. Attorney Eric Wagner against JPMorgan Chase and discusses the investigation of New York Attorney General Eric Schneiderman into the pre-crash activities on Wall Street. Cohan’s article “Jamie Dimon’s $13 Billion Secret” is the cover story in the Sept 1/8 issue of The Nation.
