"Generally, the homeland security appropriations bill includes all annual appropriations for the Department of Homeland Security (DHS), providing resources to every departmental component. The following figures show two perspectives on the budget authority for DHS enacted for FY2016 and requested by the Barack Obama Administration for FY2017, as well as the funding levels provided in the committee-reported homeland security appropriations bills and enacted FY2017 DHS appropriations. On March 16, 2017, the Donald J. Trump Administration submitted an amendment to the FY2017 budget request, which included a request for $3 billion in additional funding for DHS. The appropriations committees responded to this request for additional funding in a sixth title of the DHS appropriations act. On September 1, 2017, the Trump Administration requested an additional $7.85 billion in supplemental funding for FY2017, including $7.4 billion for the DHS--specifically for the Federal Emergency Management Agency's Disaster Relief Fund. On September 6, the House passed the relief package requested by the Administration as an amendment to H.R. 601. On September 7, the Senate passed an amended version as part of a broader relief package. The House passed the Senate amended version of the bill on September 8, which was signed into law as P.L. 115-56. This fact sheet reflects this supplemental funding separately from the annual appropriations in the first five titles, and presents the original FY2017 Obama Administration budget request unamended, because it was the basis for the annual appropriations reflected in the FY2017 measure."
