I believe that information was from Berg himself who would know. NOW, however the new information is Obama has hired 3 LAW FIRMS to handle all the lawsuits. That information is from one of the attorney's suing Obama. On http://www.aunetwork.tv/ you can listen and see who it was from.
Since you have not once heard anything from Obama himself on these lawsuits why would you think he would have information available on the costs incurred?
How would the “Truther” Berg know how much money Obama has spent on lawyers defending himself?
