Immigration Enforcement: Immigration-Related Prosecutions Increased from 2017 to 2018 in Response to U.S. Attorney General's Direction, Report to the Chairwoman, Subcommittee on Immigration and Citizenship, Committee on the Judiciary, House of Representatives [open pdf - 2MB]
From the Highlights: "In 2017 and 2018, the Attorney General directed federal prosecutors to prioritize prosecutions of immigration-related offenses, including improper entry into the United States, illegal reentry after a prior removal from the country, and alien smuggling, among other offenses. Most individuals prosecuted for such offenses are arrested by DHS's U.S. Border Patrol and referred to DOJ's [Department of Justice] USAOs [U.S. Attorney's Offices] for prosecution in federal court. GAO [Government Accountability Office] was asked to review the actions DOJ, DHS, and the federal judiciary took in response to the 2017 and 2018 memoranda. GAO reviewed (1) how DOJ prioritized prosecutions of immigration-related offenses in response to the Attorney General's memoranda, (2) what DHS and DOJ data from fiscal years 2014 through 2018 indicate about such prosecutions, and (3) resources that DOJ, DHS, and the federal judiciary used to support increased immigration-related prosecutions."
