This includes 4 references to ensuring funds don't go to ACORN (HuffPo quotes them in this article (http://www.huffingtonpost.com/2014/0...n_4594949.html) but sadly doesn't provide exact locations for them and I can't dig them up now.

Will have to check for additional issues, but it absolutely backs up ongoing GOP efforts to continue to deny funding to an organization which hasn't existed for years.
