A letter report issued by the Government Accountability Office with an abstract that begins "GAO is required to audit the consolidated financial statements of the U.S. government. Because of the significance of the federal debt held by the public to the governmentwide financial statements, GAO audits the Bureau of the Public Debt's (BPD) Schedules of Federal Debt annually to determine whether, in all material respects, (1) the schedules are reliable and (2) BPD management maintained effective internal control over financial reporting relevant to the Schedule of Federal Debt. Further, GAO tests compliance with a significant provision of law related to the Schedule of Federal Debt (statutory debt limit). Federal debt managed by BPD consists of Treasury securities held by the public and by certain federal government accounts, referred to as intragovernmental debt holdings. Debt held by the public primarily represents the amount the federal government has borrowed to finance cumulative cash deficits. Intragovernmental debt holdings represent balances of Treasury securities held by federal government accounts, primarily federal trust funds, that typically have an obligation to invest their excess annual receipts (including interest earnings) over disbursements in federal securities."

A letter report issued by the Government Accountability Office with an abstract that begins "The United States legally imported more than 1 billion live animals from 2005 through 2008. With increased trade and travel, zoonotic diseases (transmitted between animals and humans) and animal diseases can emerge anywhere and spread rapidly. The importation of live animals is governed by five principal statutes and implemented by four agencies. GAO was asked to examine, among other things, (1) potential gaps in the statutory and regulatory framework governing live animal imports, if any, that may allow the introduction and spread of zoonotic and animal diseases and (2) the extent to which the agencies collaborate to meet their responsibilities, and face barriers, if any, to collaboration. GAO reviewed statutes, met with agency officials, visited ports of entry, and surveyed experts on animal imports."
