Family and Medical Leave Act

Personnel Management Office | Rule | The Office of Personnel Management (OPM) is issuing a direct final rule making technical revisions to OPM's Family and Medical Leave Act (FMLA) regulations to incorporate various statutory amendments. The rule reflects statutory changes making virtually all Federal civilian service and certain honorable active military service qualify for determining FMLA eligibility, making clear that annual and sick leave provided under an authority outside of title 5, United States Code, may be substituted for unpaid FMLA leave, and excluding certain Veterans Health Administration (VHA) employees from title 5 FMLA coverage.

Artificial Intelligence: Actions and Opportunities to Implement Responsible Use in DOD

What GAO Found Artificial intelligence (AI) is being used in a variety of scenarios, or use cases, in the Department of Defense (DOD). In guidance, DOD established AI Ethical Principles and the concept of Responsible AI to ensure the safety and trustworthiness of AI systems. DOD further defined six tenets to guide Responsible AI implementation. Most of the 10 DOD components GAO surveyed reported taking at least initial steps to establish oversight and implement Responsible AI tenets in the selected surveyed use cases. The Office of the Chief Digital and AI Officer (CDAO), through its Responsible AI Division, established the Responsible AI Working Council as the working-level collaborative g.

Precision Navigation Systems: Challenges Remain with Fielding New Capabilities

What GAO Found The Department of Defense’s (DOD) efforts to modernize GPS continue to face delays. In response, DOD is developing new complementary sources of positioning, navigation, and timing (PNT) data to mitigate GPS threats. In 2026, after years of delays, DOD canceled the Next Generation Operational Control System ground control system and began modernizing the existing GPS Operational Control Segment. Among other effects, this creates risks for the launch, checkout, and operation of new GPS satellites. Given ongoing threats to GPS, DOD is operating and continuing development of (1) satellite-based PNT systems, (2) non-satellite-based PNT systems, and (3) backup timing solutions. Ope.

Public Health Preparedness: Action Needed to Address National and Biosecurity Risks Associated with Disposal of Federal Laboratory Equipment

What GAO Found The Department of Health and Human Services (HHS) and the U.S. Department of Agriculture (USDA) sold 1,316 pieces of unneeded laboratory equipment in fiscal years 2022 through 2025. Of that 1,316, GAO identified nine pieces of equipment–freeze dryers and mass spectrometers–that were on the Commerce Control List and sold to individuals and companies in the U.S. and Canada, some of which appeared to be resellers. These items are subject to export controls because they could be used by certain countries of concern to develop biological weapons or to gain a military advantage. Examples of Laboratory Equipment on the Commerce Control List GAO found that HHS and USDA, in selling th.

Firearms Trafficking to Mexico: Better Data and Performance Monitoring Would Help Agencies Direct Resources to Counter Cartels

What GAO Found Transnational criminal organizations (TCO) in Mexico seek to acquire semi-automatic firearms—AR-15s, AK-47s, and .50-caliber rifles—which they often convert to fully automatic firearms, according to agency officials. Armed with these weapons, TCOs pose a serious threat to Mexican law enforcement and military. TCOs acquire firearms from the U.S. primarily through straw purchasers—third parties who buy them on the TCOs’ behalf—and middlemen who smuggle the firearms through ports of entry on the border. U.S. agencies collect data on trafficked firearms, but some data have limitations that limit their utility. The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) reported.

Military Installations: Remote and Isolated Locations Face Challenges Delivering Critical Support Services

What GAO Found Remote and isolated military installations are often away from population centers or located in austere environments, making the delivery of critical support services, such as health care or housing, challenging. GAO found that while remote and isolated installations consistently faced challenges in areas such as recruiting and retaining civilian personnel, the causes and severity of those challenges differed by location. For example, in Alaska, Eielson Air Force Base had the most vacant positions (428) while Fort Greely and Clear Space Force Station had no vacant critical support services positions. In 2024, the Department of Defense (DOD) issued guidance for designating ins.

Telecommunications: Better Information Sharing Needed to Ensure Compliance with Foreign-Sourced Equipment Prohibitions

What GAO Found Section 889 of the John S. McCain National Defense Authorization Act for Fiscal Year 2019 prohibits federal agencies from procuring covered telecommunications and surveillance equipment and services from five specific Chinese companies (and their affiliates or subsidiaries) or awarding contracts to companies that use such equipment and services. Following implementation in fiscal year 2019, agencies reduced spending with the five companies through fiscal year 2025 with no spending in three of those fiscal years. As of March 2026, GAO found that nearly 90 percent of companies with active government contracts in fiscal year 2025 represented publicly that they do not use equipme.

Coast Guard: Opportunities Remain to Improve Access to Housing

Coast Guard personnel who work near vacation destinations or in remote areas experience challenges accessing private sector housing. Implementing our prior recommendations can better position the military services to manage military housing and support service members and their families. The Big Picture Due to rising costs, Coast Guard service members, 40 percent of whom rotate to new duty stations annually, and their families find it increasingly difficult to access adequate housing. The Department of Defense (DOD) and the Coast Guard (within the Department of Homeland Security) rely on the private sector to house the majority of service members; other service members may reside in governm.

DOD Installation Services: Action Needed to Improve Oversight of Intergovernmental Support Agreements

What GAO Found Based on data provided by the military services, GAO found that the services’ use of intergovernmental support agreements (IGSA) with state, local, and tribal government entities (public partners) for installation-support services increased from 45 across all DOD installations in 2018 to 316 in 2025. Officials from DOD, the Army and Navy, and selected military installations said they intend to promote future IGSA use. However, military services’ estimates of cost savings did not reflect best practices for cost estimation, which raises questions about their completeness and reliability. Further, the military services’ guidance related to estimating costs and cost savings did n.

Defense Management: DOD Needs to Review Its Defense Agencies and Field Activities for Efficiency and Effectiveness

What GAO Found The Department of Defense (DOD) has not recently met statutory requirements to review and report on the efficiency and effectiveness of its defense agencies and DOD field activities (DAFA). Between April 2023 and September 2024, DOD conducted a review of four DAFAs. However, the department did not finalize the reports based on its reviews or submit the reports to Congress as required. DOD did not have formalized guidance, such as an instruction, in place when conducting these four DAFA reviews. In May 2026, DOD issued a memorandum for future DAFA reviews that includes responsibilities and deadlines. While this is a positive step, DOD previously issued a memorandum for this ef.

National Security Space: DOD Has Opportunities to Improve Its Use of Commercial Data and Related Services

What GAO Found The U.S. commercial space sector has grown rapidly over the last few years, and offers data and data-related services—such as the imagery below—that the Department of Defense (DOD) uses to maintain national security. National Reconnaissance Office Purchased Commercial Images of Chinese Aircraft Carriers Within the Space Force, the Joint Commercial Operations Cell (JCO)—the main organization that buys data and services—purchased various types of data and services through the contractor-operated Global Data Marketplace. JCO expended $76.8 million on data and services from the marketplace from January 2023 through September 2025. These purchases supported missions including spac.
