T he mission of the Department of Justice (DOJ) is to "enforce the law and defend the interests of the United States according to the law; to ensure public safety against threats foreign and domestic; to provide federal leadership in preventing and controlling crime; to seek just punishment for those guilty of unlawful behavior; and to ensure fair and impartial administration of justice for all Americans." DOJ was established in 1870 with the Attorney General as its leader. Since its creation, DOJ has added additional agencies, components, offices, boards, and divisions to its organizational structure. DOJ, along with the judicial branch, operates the federal criminal justice system. The department enforces federal criminal and civil laws, including antitrust, civil rights, environmental, and tax laws. Through agencies such as the Federal Bureau of Investigation (FBI); the Drug Enforcement Administration (DEA); and the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF), it investigates terrorism, organized and violent crime, illegal drugs, and gun and explosives violations, among others. Through the U.S. Marshals Service (USMS), it protects the federal judiciary, apprehends fugitives, and detains alleged offenders who are not granted pretrial release. DOJ investigates and prosecutes individuals accused of violating federal laws, and it represents the U.S. government in court. DOJ's Bureau of Prisons (BOP) houses individuals accused and convicted of federal crimes. In addition to its role in administering the federal criminal justice system, the department also provides grants and training to state, local, and tribal law enforcement agencies and judicial and correctional systems. This report describes actions taken by the Administration and Congress to provide FY2018 funding for DOJ. It also provides an overview of some of the funding proposals put forth by the Administration in its FY2018 budget request for DOJ. Each of DOJ's accounts are usually funded as a part of the annual Commerce, Justice, Science, and Related Agencies (CJS) appropriations act. Accounts under the General Administration heading provide funds for salaries and expenses for the Attorney General's office, the Inspector General's office, and other programs designed to ensure that the efforts of DOJ agencies, offices, boards, and divisions are coordinated, economical, and efficient. The Salaries and Expenses account supports the Attorney General and senior DOJ leadership as they manage DOJ's resources and formulate policies for legal, law enforcement, and criminal justice activities. The Justice Information Sharing Technology account provides funding for DOJ's information technology programs. In FY2017, Congress and the President changed the title of the Administrative Review and Appeals account to the Executive Office for Immigration Review (EOIR) account. Funding for the Pardon Attorney, which was previously part of the Administrative Review and Appeals account, was moved to the General Legal Activities account. The EOIR is responsible for the review and adjudication of immigration cases, in coordination with the Department of Homeland Security (DHS). The OIG account supports efforts to detect and deter waste, fraud, and abuse involving DOJ programs and personnel; promote economy and efficiency in DOJ operations; and investigate allegations of departmental misconduct. The U.S. Parole Commission account supports the commission's mission to adjudicate parole requests for prisoners who are serving felony sentences for federal and District of Columbia criminal code violations. The commission also sets the conditions of release for offenders under its jurisdiction and makes determinations about whether to return parolees who have violated the terms of their release to prison. The Legal Activities account includes several subaccounts: General Legal Activities, U.S. Attorneys, the Antitrust Division, the Vaccine Injury Compensation Trust Fund, the U.S. Trustee System Fund, the Foreign Claims Settlement Commission, Fees and Expenses of Witnesses, and the Community Relations Service. These subaccounts support a wide array of activities. For example, the General Legal Activities subaccount funds the Office of the Solicitor General to supervise and conduct government litigation in proceedings before the Supreme Court. It also funds the activities of several DOJ divisions (tax, criminal, civil, environment and natural resources, legal counsel, civil rights, INTERPOL, and dispute resolution) . Via this account, Congress and the President also establish a limit on how much can be spent from the Assets Forfeiture Fund to cover certain authorized expenses. The USMS account supports the protection of the federal judicial process, including protecting judges, attorneys, witnesses, and jurors. In addition, the USMS provides physical security in courthouses, transports prisoners to and from court proceedings, apprehends fugitives, executes warrants and court orders, oversees the detention of alleged offenders pretrial, and seizes forfeited property. The NSD account supports the coordination of DOJ's national security and terrorism missions. The NSD was established in DOJ in response to the recommendations of the Commission on the Intelligence Capabilities of the United States Regarding Weapons of Mass Destruction (WMD Commission), and authorized by Congress and the President in the USA PATRIOT Improvement and Reauthorization Act of 2005 ( P.L. 109-177 , enacted March 9, 2006). Under the NSD, the Office of Intelligence Policy and Review and the Criminal Division's Counterterrorism and Counterespionage Sections' resources were consolidated to coordinate the department's intelligence-related resources and to ensure that criminal intelligence information is shared, as appropriate. The Interagency Law Enforcement account reimburses DOJ agencies for their participation in the Organized Crime Drug Enforcement Task Force (OCDETF) program. Organized into 12 task forces, this program combines the expertise of federal agencies with those of state and local law enforcement to disrupt and dismantle major narcotics trafficking and money laundering organizations. The DOJ agencies, divisions, and offices that participate in OCDETF are the DEA, FBI, ATF, USMS, the Tax and Criminal Divisions of DOJ, and U.S. Attorneys. Other agencies participating in OCDETF are U.S. Immigration and Customs Enforcement, the U.S. Coast Guard, the Treasury Office of Enforcement, and the Internal Revenue Service. The FBI account supports the lead federal investigative agency charged with defending the country against foreign terrorist and intelligence threats; enforcing federal laws; and providing leadership and criminal justice services to federal, state, local, tribal, and territorial law enforcement agencies and partners. Since the September 11, 2001 (9/11) terrorist attacks the FBI has reorganized and reprioritized its efforts to focus on preventing terrorism and related criminal activities. The DEA account supports the only single-mission federal agency tasked with enforcing the nation's controlled substance laws, reducing the availability and abuse of illicit drugs, and preventing the diversion of licit drugs for illicit purposes. The DEA's enforcement efforts include the disruption and dismantling of drug trafficking and money laundering organizations through drug interdiction and seizures of illicit revenues and assets derived from these organizations. The agency plays a key role in federal efforts to counter drug-related violence by focusing on the convergent threats of illegal drugs, drug-related violence, and terrorism. The DEA also has an active role in the Prescription Drug Abuse Prevention Plan through the targeting of improper prescribing practices and promoting proper disposal of unused prescription drugs. The ATF enforces federal criminal law related to the manufacture, importation, and distribution of alcohol, tobacco, firearms, and explosives. The ATF works independently and through partnerships with industry groups; international, state, and local governments; and other federal agencies to investigate and reduce crime involving firearms and explosives, acts of arson, and illegal trafficking of alcohol and tobacco products. BOP was established in 1930, and its account supports the housing of federal inmates, professionalization of the prison service, and the consistent and centralized administration of the federal prison system. The mission of the BOP is to protect society by confining offenders in prisons and community-based facilities that are safe, humane, cost-efficient, and appropriately secure, and to provide work and other self-improvement opportunities for inmates so that they can become productive citizens after they are released. The BOP currently operates 122 correctional facilities across the country. It also contracts with Residential Re-entry Centers (RRCs, i.e., halfway houses) to provide assistance to inmates nearing release. RRCs provide inmates with a structured and supervised environment along with employment counseling, job placement services, financial management assistance, and other programs and services. OVW was established to administer programs created under the Violence Against Women Act of 1994 (VAWA) and subsequent legislation. The OVW account and the programs it supports provide financial and technical assistance to communities around the country to facilitate the creation of local programs, policies, and practices designed to improve the criminal justice response to domestic violence, dating violence, sexual assault, and stalking. OJP manages and coordinates the National Institute of Justice; Bureau of Justice Statistics; Office of Juvenile Justice and Delinquency Prevention; Office for Victims of Crime; Bureau of Justice Assistance; the Office of Sex Offender Sentencing, Monitoring, Apprehending, Registering, and Tracking; and related grant programs. The Research, Evaluation, and Statistics account (formerly the Justice Assistance account) funds the operations of the Bureau of Justice Statistics and the National Institute of Justice, among other related activities. The State and Local Law Enforcement Assistance account includes funding for a variety of grant programs to improve the functioning of state, local, and tribal criminal justice systems. Some examples of programs that have traditionally been funded under this account include the Edward Byrne Memorial Justice Assistance Grant (JAG) program, the Drug Courts program, the State Criminal Alien Assistance Program (SCAAP), and DNA backlog reduction program. The Juvenile Justice Programs account includes funding for grant programs administered by the Office of Juvenile Justice and Delinquency Prevention to reduce juvenile delinquency and help state, local, and tribal governments improve the functioning of their juvenile justice systems.
