ACORN 2009 undercover videos controversy

The videos were published on Andrew Breitbart's website BigGovernment from September through November 2009. They generated extensive, negative publicity for ACORN, and led to the United States Census Bureau and the IRS ending their contracts with ACORN, the U.S. Congress suspending its funding, and ACORN losing most of its private funding. This was despite several independent investigations that by December 2009 appeared to reveal that no criminal activity by ACORN staff had taken place.
ACORN filed for Chapter 7 liquidation on November 2, 2010, effectively closing the organization. Provided by Wikipedia
