"The Consolidated Appropriations Act, 2017 (P.L. 115-31) appropriated $28.962 billion for DOJ [Department of Justice]. The act provided $2.713 billion for the U.S. Marshals [USMS], $9.006 billion for the FBI, $2.103 billion for the DEA [Drug Enforcement Administration], $1.259 billion for the ATF [ Bureau of Alcohol, Tobacco, Firearms, and Explosives], and $7.142 billion for the BOP [Bureau of Prisons]. The remaining funding (approximately $6.739 billion) was for DOJ's other offices, such as the U.S. Attorneys offices, the Executive Office for Immigration Review, and the Attorney General's office. The Trump Administration requests $28.205 billion for DOJ for FY2018. This amount is 2.6% less than the FY2017-enacted appropriation. The Administration proposes reductions for several DOJ accounts, including a $232 million (-2.6%) reduction for the FBI, a $340 million (-26.6%) reduction for State and Local Law Enforcement Assistance, and a $21 million (-8.3%) reduction for Juvenile Justice Programs. While the Administration's FY2018 budget request includes several reductions for DOJ accounts, it also includes several increases, including an additional $22 million (1.1%) for the Office of the United States Attorneys, an $82 million (5.6%) increase for the USMS's Federal Prisoner Detention account, a $76 million (1.1%) increase for BOP's Salaries and Expenses account, and a $61 million (2.9%) increase for the DEA."
