By the authority vested in me as President by the Constitution and the laws of the United States of America, I hereby order as follows:
Section 1. Policy. Every few days in the United States, we mourn a new mass shooting. Daily acts of gun violence—including community violence, domestic violence, suicide, and accidental shootings—may not always make the evening news, but they too cut lives short and leave survivors and their communities with long-lasting physical and mental wounds. We cannot accept these facts as the enduring reality of life in America. Instead, we must together insist that we have had enough, and that we will no longer allow the interests of the gun manufacturers to win out over the safety of our children and Nation.
It is the policy of my Administration that executive departments and agencies (agencies) will pursue every legally available and appropriate action to reduce gun violence. Through this whole-of-government approach, my Administration has made historic progress to save lives. My Administration has taken action to keep guns out of dangerous hands and especially dangerous weapons off of our streets; hold gun traffickers and rogue gun dealers accountable; fund accountable, effective community policing; and invest in community violence interventions and prevention strategies.
Last year, I signed into law the Bipartisan Safer Communities Act [Pub. L. 117–159, see Tables for classification] (the “Act”), the most significant bipartisan gun safety legislation in nearly 30 years. The Act provides communities with new tools to combat gun violence, including enhanced gun background checks for individuals under age 21, funding for extreme risk protection orders and other crisis interventions, and increased mental health resources to help children impacted by gun violence heal from the resulting grief and trauma.
I continue to call on the Congress to take additional action to reduce gun violence, including by banning assault weapons and high-capacity magazines, requiring background checks for all gun sales, requiring safe storage of firearms, funding my comprehensive Safer America Plan, and expanding community violence intervention and prevention strategies. In the meantime, my Administration will continue to do all that we can, within existing authority, to make our communities safer.
Sec. 2. Implementation of the Bipartisan Safer Communities Act. The Attorney General, the Secretary of Health and Human Services, the Secretary of Education, and the Secretary of Homeland Security shall each submit a report to the President within 60 days of the date of this order [Mar. 14, 2023] describing what actions their respective agencies have taken to implement the Act, data and analysis regarding the use and early effects of the Act, and additional steps their respective agencies will take to maximize the benefits of the Act. These reports shall include a plan for increasing public awareness and use of resources made available by the Act.
Sec. 3. Additional Agency Actions to Reduce Gun Violence. (a) The Attorney General shall develop and implement a plan to:
(i) clarify the definition of who is engaged in the business of dealing in firearms, and thus required to become Federal firearms licensees (FFLs), in order to increase compliance with the Federal background check requirement for firearm sales, including by considering a rulemaking, as appropriate and consistent with applicable law;
(ii) prevent former FFLs whose licenses have been revoked or surrendered from continuing to engage in the business of dealing in firearms;
(iii) publicly release, to the fullest extent permissible by law, inspection reports of FFL dealers cited for violations of the law; and
(iv) support efforts to modernize and make permanent the Undetectable Firearms Act [of 1988] ([enacting] 18 U.S.C. 922(p)).
(b) The Secretary of Defense; the Attorney General; the Secretary of Homeland Security; the Secretary of Health and Human Services, including through the Surgeon General of the United States; the Secretary of Education; and the Secretary of Veterans Affairs shall expand existing Federal campaigns and other efforts to promote safe storage of firearms.
(c) The Secretary of Defense; the Attorney General; the Secretary of Homeland Security; the Secretary of Health and Human Services, including through the Surgeon General of the United States; and the Secretary of Education shall undertake efforts to encourage effective use of extreme risk protection orders (“red flag” laws), partnering with law enforcement, health care providers, educators, and other community leaders.
(d) The Attorney General; the Secretary of Health and Human Services, including through the Surgeon General of the United States; the Secretary of Education; the Secretary of Homeland Security; the Director of the Office of Management and Budget; and the heads of other agencies, as appropriate, shall develop a proposal for the President, and submit it no later than September 15, 2023, on how the Federal Government can better support the recovery, mental health, and other needs of survivors of gun violence, families of victims and survivors of gun violence, first responders to incidents of gun violence, and communities affected by gun violence. The proposal should draw on existing evidence, where available, and take into account how to address needs in both the immediate aftermath of mass shootings and in the years following such events. The proposal should recommend any additional executive branch coordination and additional resources or authorities from the Congress needed to implement the proposal, as well as how agencies will assess the outcomes for the activities implemented.
(e) The Secretary of Defense, in consultation with the Attorney General and the Secretary of Homeland Security, shall develop and implement principles to further firearm and public safety practices through the Department of Defense’s acquisition of firearms, consistent with applicable law.
(f) The heads of Federal law enforcement agencies shall, as soon as practicable, but no later than 180 days from the date of this order, ensure that their respective law enforcement components issue National Integrated Ballistic Information Network (NIBIN) submission and utilization policies with requirements that are equivalent to, or exceed, the requirements of the policy issued by the Department of Justice on December 12, 2022, to ensure the prompt entry of ballistics data recovered in connection with criminal investigations into NIBIN. In consultation with the Department of Justice, the Department of Defense policies may be tailored to address specific operational considerations.
(g) The Secretary of Transportation, in consultation with the Department of Justice, shall work to reduce the loss or theft of firearms during shipment between FFLs and to improve reporting of such losses or thefts, including by engaging with carriers and shippers.
(h) The Federal Trade Commission is encouraged to issue a public report analyzing how gun manufacturers market firearms to minors and how such manufacturers market firearms to civilians, including through the use of military imagery.
Sec. 4. Definitions. For purposes of this order, the term “Federal law enforcement agency” means an organizational unit or subunit of the executive branch that employs officers who are authorized to make arrests and carry firearms, and that is responsible for the prevention, detection, and investigation of crime or the apprehension of alleged offenders. The term “heads of Federal law enforcement agencies” means the heads of those units or subunits.
Sec. 5. General Provisions. (a) Nothing in this order shall be construed to impair or otherwise affect:
(i) the authority granted by law to an executive department or agency, or the head thereof; or
(ii) the functions of the Director of the Office of Management and Budget relating to budgetary, administrative, or legislative proposals.
(b) This order shall be implemented consistent with applicable law and subject to the availability of appropriations.
(c) This order is not intended to, and does not, create any right or benefit, substantive or procedural, enforceable at law or in equity by any party against the United States, its departments, agencies, or entities, its officers, employees, or agents, or any other person.
Ex. Ord. No. 14127, Sept. 26, 2024, 89 F.R. 80345, provided:
By the authority vested in me as President by the Constitution and the laws of the United States of America, it is hereby ordered as follows:
Section 1. Policy. During 2020, the last year of the prior administration, homicides in the Nation increased nearly 30 percent over the previous year—the largest 1-year increase in murders ever recorded. After that, the Vice President and I took action to reduce gun crime and other forms of violent crime. By the middle of 2022, we had already taken more executive action to reduce gun violence than any other administration at that point in time. On June 25, 2022, I signed into law the Bipartisan Safer Communities Act (Public Law 117–159)—the most significant new gun violence prevention law in nearly 30 years. Rates of homicide in the United States are falling at one of the fastest rates ever recorded. Year-over-year comparison shows that 2023 had one of the largest declines in the homicide rate in recent history. This life-saving progress has continued in 2024. While we have made great progress, much more work remains to be done to reduce gun violence and save lives.
It is the policy of my Administration to coordinate across executive departments and agencies (agencies) to reduce gun violence and save lives. This order directs enhanced coordination for two key challenges: combating emerging firearms threats and understanding and improving school-based active-shooter drills.
One way to continue the progress on reducing gun violence is to stay ahead of emerging violent crime threats involving firearms. My Administration has always taken these threats seriously. In April 2021, one of my Administration’s first executive actions to reduce gun violence was directed at stopping the proliferation of firearms without serial numbers, often referred to as “ghost guns.” To expand these efforts, the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF) of the Department of Justice established an Emerging Threats Center, which focuses ATF’s resources on identifying developments in illicit firearm marketplaces, including the use of new technologies to make and unlawfully distribute undetectable firearms and devices that convert semiautomatic firearms into illegal machineguns. The Vice President and I strongly disagreed with the Supreme Court’s decision to strike down an important gun safety regulation on bump stocks—the device used in the shooting at a crowded music festival in Las Vegas—and called on the Congress to clarify that this dangerous accessory is a machinegun.
The Court’s decision addressing bump stocks did not alter the statutory prohibition on machinegun conversion devices, which are prohibited for non-governmental possession even when not installed on a firearm. The threat posed by the continued proliferation of these devices is particularly acute. These devices enable semiautomatic firearms, including easily concealable handguns, to match or exceed the rate of fire of many military machineguns with a single engagement of the trigger—up to 20 bullets in one second and 1,200 rounds in one minute. From 2017 through 2021, ATF recovered 5,454 of these devices—a 570 percent increase over the previous 5-year period. These devices are often illegally imported or illegally made on a 3D printer.
Unserialized, 3D printed firearms—which can be used for illicit purposes such as gun trafficking, possession by people convicted of felonies or subject to domestic violence restraining orders, or unlawful engagement in the business of manufacturing or selling firearms—are another emerging threat. These firearms can be 3D printed from computer code downloaded from the internet and produced without serial numbers, which law enforcement uses to trace firearms recovered in criminal investigations. Some 3D printed firearms can be rendered undetectable by magnetometers used to secure airports, courthouses, and certain events. 3D printing technology is developing quickly, which can cause the safety threat of 3D printed firearms to suddenly increase.
In addition to the threat of domestic crime, these emerging firearms threats pose a significant risk to the national security and foreign policy interests of the United States. Many foreign countries have heavily regulated automatic weapons and 3D printed and undetectable firearms. The wide availability of these emerging firearms threats would undermine other nations’ gun laws and the safety and security of our allies. Technical data and software for 3D printed firearms and machinegun conversion devices can be used by international gangs, criminals, and terrorists in a manner contrary to United States national security and foreign policy interests.
Multiple agencies have the authority to help stop the proliferation of these emerging threats, and it is the policy of the United States to work collectively across agencies to identify threats, engage in information sharing, and work together to develop and implement effective strategies to combat these threats. Authorities that can address emerging firearms threats extend beyond the Gun Control Act [of 1968] (Public Law 90–618) and the National Firearms Act (Public Law 73–474) [see 26 U.S.C. 5801 et seq.]. Focused and enhanced coordination is needed to ensure a unified and robust strategy for enforcing existing legal authorities and using every available tool and resource. This interagency effort will build on the life-saving work that has occurred to date to stop the proliferation of machinegun conversion devices, including the ongoing efforts at the Department of Justice and ATF.
My Administration also has invested significant resources in school safety and has taken steps to keeps firearms out of schools. These steps have focused on preventing unauthorized access to firearms for youth and individuals in crisis; supporting schools that are implementing evidence-based safety and gun-violence prevention and intervention solutions; and addressing the mental health needs of students, particularly those impacted by gun violence.
Keeping students and educators, including teachers and other school personnel, safe from gun violence in their schools is a top priority for my Administration, but there is more to do to make our schools safer. Since the mass shooting at Columbine High School in Colorado in 1999, according to one analysis, there have been more than 400 school shootings that exposed more than 375,000 students to gun violence. Exposure to school shootings takes a terrible toll on students and educators. A nationally representative study found that 51 percent of 14- to 17-year-olds in the United States worry about school shootings.
The majority of States require schools to conduct active-shooter drills for students and educators. About 95 percent of K–12 public schools in the United States conduct lockdown drills, which include drills to prepare for an active-shooter situation. These drills vary widely in their approach, and many parents, students, and educators have expressed concerns over the effectiveness of and trauma caused by some approaches to these drills.
Despite their ubiquity, there is very limited research on how to design and deploy these drills to maximize their effectiveness and minimize any collateral harms they might cause. While additional research is ongoing, it is difficult to conclusively determine which specific practices are most effective in preparing schools for active-shooter incidents, preventing injuries and fatalities, and minimizing any associated psychological impacts or traumas. The Department of Justice, the Department of Health and Human Services, the Department of Education, and the Department of Homeland Security continue to work together on a range of school safety issues, including the beginnings of research into these important questions. It is time for these agencies to extend their efforts to help schools better design and conduct effective and age- and developmentally appropriate active-shooter drills.
Sec. 2. Definitions. For purposes of this order:
(a) The term “machinegun” has the meaning given by 18 U.S.C. 921(a)(24) and 26 U.S.C. 5845(b), and includes a “machinegun conversion device,” which is any part designed and intended solely and exclusively, or combination of parts designed and intended, for use in converting a weapon into a machinegun.
(b) The term “undetectable firearm” means a firearm as proscribed by 18 U.S.C. 922(p).
(c) The term “3D printing” refers to the additive manufacturing process, during which producers transmit digital designs to 3D printers. The computerized design guides the fabrication of products, building them up layer by layer rather than cutting away from a large block of existing material as in most traditional manufacturing. This term includes additive manufacturing technology used to produce a firearm, firearm frame or receiver, or machinegun conversion device.
