The Trump administration has frozen more than $1 billion in federal Medicaid funding to California and Minnesota amid concerns about fraud and compliance, with Health and Human Services Secretary Robert F. Kennedy Jr. saying the states will not receive further funding until they prove the payments were legitimate. The move escalates tensions between the federal government and two Democratic-led states over the handling of taxpayer-funded healthcare programmes, raising questions about oversight of state Medicaid spending.

Kennedy said the funding could be released quickly if the states provide basic documentation showing the services in question are legitimate, directly naming California Governor Gavin Newsom and Minnesota Governor Tim Walz. The pause reflects wider scrutiny of Medicaid programmes for potential fraud and improper payments, though the article does not specify further detail on the exact nature of the alleged compliance failures.
