The gross federal debt, which represents the federal government's total outstanding debt, consists of two types of debt: (1) debt held by the public and (2) debt held in government accounts, also known as intragovernmental debt. Federal government borrowing increases for two primary reasons: (1) budget deficits and (2) investments of any federal government account surpluses in Treasury securities, as required by law. Nearly all of this debt is subject to the statutory limit. The federal debt limit currently stands at $14,294 billion.

In August 2011, the Obama Administration announced its counter-radicalization strategy. It is devised to address the forces that influence some people living in the United States to acquire and hold radical or extremist beliefs that may eventually compel them to commit terrorism. This is the first such strategy for the federal government, which calls this effort “combating violent extremism” (CVE). This report provides examples of recent Administration CVE activity and examines some of the risks and challenges evident in the SIP's three objectives. The report also diagrams and briefly discusses the “future activities and efforts” outlined in the SIP for each of these three objectives. A number of areas may call for oversight from Congress. These include the following: picking partners and establishing "rules of the road," intervention with at-risk individuals, identifying programs to assist grassroots CVE efforts, countering extremist ideas, the lack of a lead agency, and transparency.

On January 13, 2012, President Obama asked Congress for authority to reorganize and consolidate into one department the business- and trade-related functions of six federal entities. U.S. policymakers' interest in the organizational structure of U.S. government trade functions has grown in recent years, stimulated by congressional and federal efforts to promote U.S. exports and employment, including through the National Export Initiative (NEI). Interest also has been stimulated by national debates on reducing federal spending and the size of the U.S. government. This report looks at the policy debate and role of Congress in such a move.

This report gives an overview of tax reform issues. The President and leading members of Congress have stated that fundamental tax reform is a major policy objective for the 112th Congress. Some Members have said that fundamental tax reform is needed in order to raise a large amount of additional revenue, which is necessary to reduce high forecast budget deficits and the sharply rising national debt. Congressional interest has been expressed in both a major overhaul of the U.S. tax system and the feasibility of levying a consumption tax.

This report describes the Keystone XL pipeline proposal and the process required for federal approval. It summarizes key arguments for and against the pipeline put forth by the pipeline's developers, federal agencies, environmental groups, and other stakeholders. The report discusses potential consistency challenges faced by the State Department in reviewing the pipeline application given its recent prior approvals of similar pipeline projects. Finally, the report reviews the constitutional basis for the State Department's authority to issue a Presidential Permit, and opponents' possible challenges to this authority.

This report surveys the legal theories invoked when laws enacted by Congress interfere with contracts entered into before enactment, prompting suits against the United States by disappointed contract parties.

This report provides examples of recent Administration "combating violent extremism" (CVE) activity and examines some of the risks and challenges evident in the Strategic Implementation Plan for Empowering Local Partners to Prevent Violent Extremism in the United States' (SIP's) three objectives. The report also diagrams and briefly discusses the "future activities and efforts" outlined in the SIP for each of these three objectives.

This report aims to provide information on the history of democracy promotion as a foreign assistance objective, the role of the primary U.S. agencies administering such programs, and funding details and trends, as well as issues of potential relevance to Congress.

This report discuses the development, procurement, and funding of the Army's new Multi-Purpose Vehicles (AMPV) intended to replace Vietnam War-era M-113 personnel carriers. The FY2018 budget request for the AMPV requests $647.4 million for the production of 107 vehicles. A potential issue for Congress is whether the Administration's proposal to increase the size of the Army will translate into a requirement for additional AMPVs.

This report discusses the Occupational Safety and Health Administration's (OSHA) newly published new standards regulating exposure to crystalline silica in the workplace. Under the new standards, the Permissible Exposure Limit (PEL) for crystalline silica will be reduced to 50 µg/m3 (micrograms per cubic meter of air). Employers will be required to monitor crystalline silica exposure if workplace levels may exceed 25 µg/m3 for at least 30 days in a year and provide medical monitoring to employees in those workplaces. In the case of construction workers, medical monitoring is required only if the new standards require workers to wear respirators for at least 30 days in a year.

This report discusses the Air Force's planned procurement of 350 new Advanced Pilot Training (APT T-X) aircraft and 46 Ground Based Training Systems (GBTS) at a cost valued at roughly $1.5 billion for the Research, Design, Test, and Evaluation phase of the program and estimated at $18 billion in future procurement costs. The APT T-X acquisition strategy poses potential oversight issues for Congress, including the following: Is the number of planned aircraft purchases sufficient? Given the reported pilot shortage, should the procurement be accelerated? What effects do increased F-35A & KC-46 purchases, along with development of the new Long Range Strike Bomber, B-21, have on the USAF budget and the feasibility of an additional Major Defense Acquisition Program? These questions and the Air Force's FY 2017 appropriations requests' for the program are addressed in this report.

This report discusses systems used by the federal government to keep track of all the different government contractors through the use of unique identifying numbers. The first section provides basic information on the Data Universal Numbering System (DUNS) which is the current system that is slowly being phased out and the Commercial and Government Entity System and Codes (CAGE) which has been being implemented more recently. The final section discusses the federal government's reliance on DUNS, interest in and exploration of alternatives to DUNS, and government actions that possibly could pave the way for the adoption of an alternative system, or a hybrid system that includes DUNS. The CAGE system, which is an existing, federal government identification system, may be a candidate for either option.

This report discusses the Low Income Housing Tax Credit (LIHTC) program which provides developers with tax credits for developing or rehabilitating affordable housing and describes how the allocation processes work.
