This bill directs the Department of Homeland Security to develop a comprehensive strategy within one year to address security threats posed by "ghost guns"—untraceable firearms that lack serial numbers or are privately made. The legislation requires DHS components, including Intelligence and Analysis, the Secret Service, the Transportation Security Administration, and Immigration and Customs Enforcement, to conduct research, assessments, and reports on ghost gun threats related to terrorism, targeted violence, and cross-border smuggling. Specifically, DHS must report on ghost guns recovered in Mexico sourced from the United States, assess how ghost guns are acquired and trafficked, and provide guidance to prevent these weapons from being used in attacks or brought onto aircraft. The bill does not specify dedicated funding but imposes reporting requirements on multiple federal agencies with annual updates to relevant congressional committees. All analysis and strategy development must be completed within one year of the bill's enactment.
