Rural and Municipal Utility Cybersecurity Act

Maddy summaryThe Rural and Municipal Utility Cybersecurity Act establishes a federal program to provide grants and technical assistance to small electric utilities, including rural cooperatives, municipally owned systems, and smaller investor-owned companies. The program aims to help these entities deploy advanced cybersecurity technologies and participate in threat information sharing networks to better protect against cyberattacks. Funding is prioritized for utilities with limited security resources or those operating critical infrastructure that supports the national power grid. The bill authorizes $250 million in appropriations over five years, from fiscal year 2027 through 2031, and exempts shared cybersecurity information from public disclosure under freedom of information laws.

Empowering States to Serve Veterans Act

Maddy summaryThe Empowering States to Serve Veterans Act requires the Department of Veterans Affairs to share veterans' contact information with state veterans agencies at least quarterly for statistical analysis and outreach purposes. The bill strictly limits the shared data by excluding protected health information, Social Security numbers, dates of birth, and any financial or claims-related details. To protect privacy, the legislation mandates that veterans receive clear notice of this sharing and provides an accessible process for them to opt out at any time, which requires state agencies to immediately destroy any previously received data. State agencies must also implement federal-standard cybersecurity measures and demonstrate compliance before receiving any information.

Fairness for Farm Workers Act

Maddy summaryThe Fairness for Farm Workers Act amends the Fair Labor Standards Act to extend overtime protections to agricultural workers, who are currently largely exempt from these requirements. The bill establishes a phased schedule requiring employers to pay farm workers time-and-a-half for hours worked beyond a threshold that decreases from 55 hours per week in 2027 to the standard 40 hours by 2030. Small farms with 25 or fewer employees are granted an additional three-year grace period, reaching full compliance by 2033. Additionally, the legislation removes several existing exemptions that allow agricultural employers to bypass federal wage and hour standards, ensuring broader coverage for workers in the sector.
