This report outlines an array of homeland security issues that may come before the 115th Congress. After a brief discussion of the definitions of homeland security, the homeland security budget, and the role of homeland security actors in the intelligence community, the report divides the specific issues into five broad categories: Counterterrorism and Security Management; Border Security and Trade; Disaster Preparedness, Response, and Recovery; Cybersecurity; and DHS Management Issues. Each of those areas contains a survey of topics briefly analyzed by Congressional Research Service experts. The information included only scratches the surface of most of these selected issues. More detailed information on these topics and others can be obtained by consulting the CRS reports referenced herein, or by contacting the relevant CRS expert.

This report serves as a primer on class action litigation in the federal courts. It begins by discussing the purpose of class actions, as well as the risks class actions may pose to defendants, class members, and society at large. The report also discusses the prerequisites that a class action must satisfy before a court may "certify" it--that is, before a federal court may allow a case to proceed as a class action. An Appendix to the report also contains a reference chart that graphically illustrates those prerequisites for class certification. The report then discusses Rule 23's restrictions on the parties' ability to settle a certified class action. The report concludes by identifying ways in which Congress could modify the legal framework governing class actions if it were so inclined, with a particular focus on a bill currently pending in the 115th Congress that would effectuate a variety of changes to the class action system.
