CBRE Group. Inc. is a commercial real estate corporation which is chaired by Richard C. Blum, who is the husband of U.S. Senator Dianne Feinstein of California. In 2011, the United States Postal Service (USPS) awarded CBRE an exclusive contract to sell off postal real estate in cities and towns across America. Based upon examining hundreds of public records, Going Postal reported that CBRE has sold more than $200 million worth of post office real estate at under fair market values, often to the firm's clients and business partners. CBRE's contract with the USPS requires the company to obtain fair market prices for properties that it brokers on behalf of the public and to avoid such conflicts of interest.
