Mystery company the largest corporate donor of 2012

A company created less than two months before Election Day was the largest corporate donor of the 2012 elections and remains shrouded in mystery weeks later.

The company, Specialty Group Inc., operated by Knoxville attorney William Rose, donated nearly $10.6 million to a Tea Party-affiliated super PAC in the campaign's final weeks as the group blistered candidates across the country with attack ads, new campaign reports show. In late October, Kingston Pike Development, another company affiliated with Rose, donated $1.5 million to the same super PAC, FreedomWorks for America.
