T his report is part of a suite of reports that discuss appropriations for the Department of Homeland Security (DHS) for FY2017. It specifically discusses appropriations for the components of DHS included in the first title of the homeland security appropriations bill—the Office of the Secretary and Executive Management, the Office of the Under Secretary for Management, the DHS headquarters consolidation project, the Office of the Chief Financial Officer, the Office of the Chief Information Officer, Analysis and Operations, and the Office of Inspector General for the department. Collectively, Congress has labeled these components in recent years as "Departmental Management and Operations," although this year, the House Appropriations Committee chose to rename the title "Departmental Management, Operations, Intelligence, and Oversight." The report provides an overview of the Administration's FY2017 request for these components, the appropriations proposed by the appropriations committees in response, and those enacted in Division F of the Consolidated Appropriations Act, 2017 ( P.L. 115-31 ). Rather than limiting the scope of its review to the first titles of the bills, the report includes information on provisions throughout the bills and report that directly affect these components. The suite of CRS reports on homeland security appropriations tracks legislative action and congressional issues related to DHS appropriations, with particular attention paid to discretionary funding amounts. The reports do not provide in-depth analysis of specific issues related to mandatory funding—such as retirement pay—nor do they systematically follow other legislation related to the authorization or amending of DHS programs, activities, or fee revenues. Discussion of appropriations legislation involves a variety of specialized budgetary concepts. The Appendix to CRS Report R44621, Department of Homeland Security Appropriations: FY2017 , explains several of these concepts, including budget authority, obligations, outlays, discretionary and mandatory spending, offsetting collections, allocations, and adjustments to the discretionary spending caps under the Budget Control Act ( P.L. 112-25 ). A more complete discussion of those terms and the appropriations process in general can be found in CRS Report R42388, The Congressional Appropriations Process: An Introduction , coordinated by [author name scrubbed], and the Government Accountability Office's A Glossary of Terms Used in the Federal Budget Process . Note on Data and Citations All amounts contained in the suite of CRS reports on homeland security appropriations represent budget authority. For precision in percentages and totals, all calculations were performed using unrounded data, which are presented in the report's tables. However, amounts in narrative discussions are generally rounded to the nearest million, unless noted otherwise. Data used in this report for FY2016 and FY2017 amounts are derived from a single source. Normally, this report would rely on previous fiscal year enacted legislation and reports, as well as House and Senate legislative efforts in response to the Administration's budget request. However, due to the implementation of the Common Appropriations Structure for DHS (see below), this report relies on the Consolidated Appropriations Act, 2017 ( P.L. 115-31 ), Division F of which is the Department of Homeland Security Appropriations Act, 2017, and the accompanying explanatory statement, which was printed in the May 3, 2017, Congressional Record . The "Common Appropriations Structure" Section 563 of Division F of P.L. 114-113 (the FY2016 Department of Homeland Security Appropriations Act) provided authority for DHS to submit its FY2017 appropriations request under the new common appropriations structure (CAS), and implement it in FY2017. Under the act, the new structure was to have four categories of appropriations: Operations and Support; Procurement, Construction, and Improvement; Research and Development; and Federal Assistance. Most of the FY2017 DHS appropriations request categorized its appropriations in this fashion. The exception was the Coast Guard, which was in the process of migrating its financial information to a new system. The House Appropriations Committee made its funding recommendation using the CAS (although it chose to implement it slightly differently than the Administration had envisioned in Title I), but the Senate Appropriations Committee did not, instead drafting its annual DHS appropriations bill and report using the same structure as was used in FY2016. No authoritative crosswalk between the House Appropriations Committee proposal in the CAS structure and Senate Appropriations Committee proposal in the legacy structure is publicly available. The explanatory statement for Division F of the Consolidated Appropriations Act, 2017, included a "detail table," outlining the new structure of DHS appropriations, as well as Programs, Projects, and Activities (PPAs)—the next level of funding detail below the appropriation level. The table showed the FY2016 enacted and FY2017 requested funding for DHS in the new structure as well, enabling the comparisons in this report. Generally, the homeland security appropriations bill includes all annual appropriations provided for DHS, allocating resources to every departmental component. Discretionary appropriations provide roughly two-thirds to three-fourths of the annual funding for DHS operations, depending on how one accounts for disaster relief spending and funding for overseas contingency operations. The remainder of the budget is a mix of fee revenues, trust funds, and mandatory spending. Appropriations measures for DHS typically have been organized into five titles. The first four are thematic groupings of components: Departmental Management and Operations; Security, Enforcement, and Investigations; Protection, Preparedness, Response, and Recovery; and Research and Development, Training, and Services. A fifth title contains general provisions, the impact of which may reach across the entire department, impact multiple components, or focus on a single activity. For FY2017, a sixth title responded to the Trump Administration's supplemental appropriations request submitted in March 2017. The following pie chart presents a visual comparison of the share of annual appropriations requested by the Obama Administration for the components funded in each of the first four titles, highlighting the components discussed in this report. As noted above, the Departmental Management and Operations title (Title I) of the DHS appropriations bill provides funding for the department's management activities, Analysis and Operations (A&O) function, and the Office of the Inspector General (OIG). Funding at times has been requested or provided for some of these functions in Title V, General Provisions, as well. Departmental Management and Operations is the smallest of the four titles that carry the bulk of funding in the bill. The Obama Administration requested $1.46 billion for these components in FY2017, $37 million less than was provided for FY2016. The amount requested for these components was 3% of the Obama Administration's $47.7 billion request in net discretionary budget authority and disaster relief funding for DHS. The proposed decrease in discretionary funding for the components is 11.1% of the total net decrease in adjusted net discretionary budget authority requested for the department. The largest budget increase proposed in the request for these components was $41 million (66%) for the Office of the Chief Procurement Officer, while the largest budget decrease proposed was the non-recurrence of a $100 million appropriation in general provisions to fund OCIO cybersecurity activities. Senate Appropriations Committee-reported S. 3001 would have provided the components included in this title $1.41 billion in net discretionary budget authority in FY2017. This would have been $24 million (1.7%) less than requested, and $62 million (4.2%) less than was provided in FY2016. House Appropriations Committee-reported H.R. 5634 would have provided the components included in this title $1.31 billion in net discretionary budget authority in FY2017. This would have been $126 million (8.6%) less than requested, and $163 million (10.8%) less than was provided in FY2016. These bills were not voted on in either body, and no annual appropriations bill for DHS was enacted prior to the end of FY2016. On September 29, 2016, the President signed into law P.L. 114-223 , which contained a continuing resolution that funds the government at the same rate of operations as FY2016, minus 0.496%, through December 9, 2016. A second continuing resolution was signed into law on December 10, 2016 ( P.L. 114-254 ), funding the government at the same rate of operations as FY2016, minus 0.1901%, through April 28, 2017, and a third ( P.L. 115-30 ) extended the second continuing resolution through May 5, 2017. The continuing resolutions were superseded by the Department of Homeland Security Appropriations Act, 2017. For details on these continuing resolutions and their impact on DHS, see CRS Report R44621, Department of Homeland Security Appropriations: FY2017 . On March 16, 2017, the Trump Administration submitted an amendment to the FY2017 budget request, which included a request for $3 billion in additional funding for DHS. Congress addressed this request at the same time as it resolved annual appropriations for the federal government, through the Consolidated Appropriations Act, 2017 (signed into law as P.L. 115-31 on May 5, 2017). The act included both annual and supplemental appropriations for DHS as Division F. It provided $41.3 billion in adjusted net discretionary budget authority in annual appropriations, as well as $6.7 billion in funding for the costs of major disasters under the Stafford Act and $163 million in funding for overseas contingency operations. Table 1 shows a brief funding history for the individual components funded under Departmental Management and Operations. It shows the funding level provided for the previous fiscal year, as well as the amounts requested for these accounts for FY2017 by the Obama and Trump Administrations, and the final level enacted in Division F of P.L. 115-31 . As noted above, no authoritative crosswalk that would allow comparisons below the component level with the House and Senate appropriations committee-reported bills is publicly available.
