On December 7, 2009, the former Massachusetts Attorney General, after an independent internal investigation of ACORN, found the videos that had been released appeared to have been edited, "in some cases substantially". He found no evidence of criminal conduct by ACORN employees, but concluded that ACORN had poor management practices that contributed to unprofessional actions by a number of its low-level employees. On March 1, 2010, the District Attorney's office for Brooklyn determined that the videos were "heavily edited" and concluded that there was no criminal wrongdoing by the ACORN staff in the videos from the Brooklyn ACORN office. On April 1, 2010, an investigation by the California Attorney General found the videos from Los Angeles, San Diego and San Bernardino to be "heavily edited", and the investigation did not find evidence of criminal conduct on the part of ACORN employees. On June 14, 2010, the U.S. Government Accountability Office (GAO) released its findings, which showed that ACORN evidenced no sign that it, or any of its related organizations, mishandled any federal money they had received. In March 2010, ACORN announced it would be closing its offices and disbanding due to loss of funding from government and private donors.
