Turns out that the realtor who gave Cunningham's contractor buddy a "fair estimate" on the property is also a longtime contributor to Cunningham.
So here's the story. Cunningham has a contributor declare that his property is worth $1,675,000. Then he sells it to a defense contractor for $1,675,000. The contractor the turns around and "flips" the house at a $700,000 loss. The contractor then starts winning lots of bids on contracts that Cunningham has oversight for.
Cunningham, I expect, will soon be retaining the services of a criminal defense attorney.
