MATCH Act of 2026

Maddy summaryThis bill establishes a new talent marketplace system to connect job seekers with employers and training programs using digital platforms that support open standards and interoperable data sharing. It creates a federal grant program requiring states to allocate 5-10 percent of workforce funds toward building these marketplaces, which include digital tools for tracking skills, verifying credentials, and generating standardized skill profiles. The legislation also mandates that states make these platforms publicly accessible through one-stop delivery systems while protecting user privacy and ensuring websites are easy to navigate and compare programs.

Heat Workforce Standards Act of 2025

Maddy summaryHR 6213, the Heat Workforce Standards Act of 2025, prohibits the U.S. Department of Labor from finalizing, implementing, or enforcing OSHA's proposed "Heat Injury and Illness Prevention" standard (published August 30, 2024). This bill directly blocks the specific regulatory proposal targeting heat safety in both outdoor and indoor work settings. It does not create new requirements or affect workers; it solely prevents the implementation of the existing OSHA proposal. The bill is procedural, focusing on halting a regulatory action rather than establishing new policy.

Daughters of the American Revolution Membership Integrity Act.

Maddy summaryThis bill, known as the Daughters of the American Revolution Membership Integrity Act, amends federal law to explicitly limit membership in the Daughters of the American Revolution to adult human females. It defines a female as someone who naturally possesses or would have the reproductive system capable of producing ova for fertilization, regardless of any congenital anomalies or medical disruptions. By adding this specific definition to the organization's governing code, the legislation clarifies the genealogical and biological requirements for joining the group. The change directly affects the organization's eligibility rules but does not alter its internal operations or funding.

Chloe Cole Act of 2026

Maddy summaryHR 7651, the Chloe Cole Act of 2026, prohibits healthcare providers from performing certain medical interventions on minors under 18 aimed at altering physical development to align with gender identity. These "covered interventions" include puberty blockers, hormone treatments, and specific surgeries, but exclude medically necessary care for conditions like disorders of sexual development or traumatic injuries. The bill creates a federal civil lawsuit right for affected minors or their parents against providers who perform such interventions, allowing claims for damages including emotional distress and punitive awards, with strict liability for providers after the law's enactment. It explicitly allows exceptions for legitimate medical treatments and requires providers to prove such exceptions apply if challenged.

Improving Seniors’ Timely Access to Care Act of 2025

Maddy summaryThis bill requires Medicare Advantage plans to implement electronic pre-approval systems for medical services by 2028 and meet transparency reporting standards starting in 2027. Plans must publicly report data on approval/denial rates, appeal outcomes, response times, and technology use for pre-approval requests, including details on how denials relate to clinical criteria. It establishes a 24-hour response timeframe for certain requests and mandates annual reviews of pre-approval requirements based on data and input from seniors and providers. The law directly affects Medicare Advantage plans, seniors enrolled in these plans, and healthcare providers who submit pre-approval requests. These changes aim to make the pre-approval process faster, more transparent, and more accountable for seniors seeking covered medical services.

PARITY Act

Maddy summaryThe PARITY Act modifies the Higher Education Act by removing specific regulatory requirements related to institutional accreditation. This change directly affects colleges and universities by eliminating the need to comply with the repealed provisions regarding their status and oversight. The bill achieves this by amending Section 487 to delete a specific paragraph and an entire subsection that previously imposed these rules.

Veteran Burial Timeliness and Death Certificate Accountability Act

Maddy summaryHR 4398, the Veteran Burial Timeliness and Death Certificate Accountability Act, requires Veterans Affairs (VA) physicians or nurse practitioners to certify the death of a veteran who dies of natural causes within 48 hours of learning of the death. This directly affects veterans' families, who previously faced delays of up to eight weeks in burial and access to survivor benefits due to slow death certifications. The bill mandates annual reports to Congress on VA compliance with the 48-hour rule, including statistics on delays and their causes. The key change is establishing a strict timeline for death certification to prevent unnecessary delays in honoring veterans' final arrangements.

UNLOCK AUKUS Act

Maddy summaryThe UNLOCK AUKUS Act modifies existing export control rules to allow the transfer of specific defense articles and services under the AUKUS partnership. By amending the Arms Export Control Act, the bill removes certain restrictions that previously limited what can be shared between partner nations. This change directly affects the U.S. government's ability to share advanced military technology with allies in the AUKUS alliance. The legislation aims to facilitate collaboration without altering the core legal framework governing defense exports.

Great American Outdoors Act 250

Maddy summaryThis bill redesignates the existing National Parks and Public Land Legacy Restoration Fund as the America's Legacy Restoration Fund to address deferred maintenance on federal lands. It directs revenue from recreation fees and a portion of energy development income into the fund, which must be used primarily for repairing critical infrastructure like roads, trails, and buildings managed by agencies such as the National Park Service and the Forest Service. The legislation establishes strict rules requiring that most funds go toward non-transportation projects, mandates transparency through public dashboards tracking project status, and sets aside a small percentage for matching private donations. Additionally, the bill increases entrance fees for foreign visitors to ensure they contribute to the fund, while prohibiting the use of these specific funds for land acquisition or employee bonuses.
