Feinstein and Hubby get Sweet deal selling off US Post Offices

The US has entered into a contract with a real estate firm to sell 56 buildings that currently house U.S. Post Offices. The government has decided it no longer needs these buildings, most of which are located on prime land in towns and cities across the country. The sale of these properties will fetch about $19 billion.  A regular real estate commission will be paid to the company that was given the exclusive listing for handling the sales.That company is CRI and it belongs to a man named Richard Blum. 
  Richard Blum is the husband of Senator Dianne Feinstein. (Most voters and many of the government people who approved the deal have not made the connection between the two because they have different last names). 
   Senator Feinstein and her husband stand to make a fortune (est at between $950 million and $1.1 billion!!) from these transactions.  His company is the sole real estate on the sale. CRI will be making a minimum of 3% and as much as 6% commission on each and every sale.   
All of the properties that are being sold are all fully paid for. They were purchased with U.S. taxpayers dollars. The U.S.P.S. is allowed free and clear, tax exempt use. The only cost to keep them open is the cost to actually keep the doors open and the heat and lights on. The United States Postal Service doesn't even have to pay county property taxes on these subject properties.   
No one in the mainstream media is even raising an eyebrow over the conflict of interest and on the possibility of corruption on the sale of billions of dollars worth of public assets.   
How does a U.S. Senator from San Francisco manage to get away with organizing and lobbying such a sweet deal? Has our government become so elitist that they have no fear of oversight?
