IRS and DOJ hiding criminal action?

In late September 2010, Iowa senator Chuck Grassley and six of his colleagues grew suspicious that a senior Obama administration official had improperly accessed the tax information of industrial behemoth Koch Industries. 

 After Austan Goolsbee, then-chairman of the president’s Council of Economic Advisers, made an erroneous statement that implied direct knowledge of the company’s confidential tax status, the senators demanded that the Treasury Department inspector general for tax administration (TIGTA) investigate. 

Now, more than two years since the completion of that investigation, and despite repeated requests from Koch Industries and Senator Grassley himself, the results have yet to see the light of day.

In order for Koch Industries or the general public to see the TIGTA report, the IG’s office must refer the case to the Department of Justice for prosecution. If Justice declines to prosecute, all the relevant information remains under lock and key. 
Critics worry that a highly politicized Justice Department is  unlikely to take up cases that have the potential to damage the Obama administration.
