The Department of Health and Human Services' Office for Civil Rights announced on March 19 that it had opened investigations into 13 states — California, Colorado, Delaware, Illinois, Maine, Maryland, Massachusetts, Minnesota, New Jersey, New York, Oregon, Vermont, and Washington — for allegedly violating the Weldon Amendment, a conscience protection provision included in federal appropriations law every year since 2005. All 13 states have laws or regulations requiring insurance plans to include coverage for abortion, which HHS OCR said amounts to coercing health care entities that object to abortion coverage on religious or moral grounds.

The Weldon Amendment bars states and local governments that receive federal funds from discriminating against any health care provider, plan, or insurer that declines to cover, pay for, or refer for abortions. The Trump administration's OCR, led by Cole Muzio, said earlier in 2026 that it had clarified its interpretation of the amendment to include employer health plans and plan sponsors — reversing a 2021 Biden-era decision that had excluded them from coverage. The investigations could ultimately result in the federal government withholding relevant funding or referring noncomplying states to the Department of Justice.

The Washington Examiner and EWTN News praised the investigations as a long-overdue enforcement action, noting that states with abortion coverage mandates had effectively been forcing Catholic hospitals, religious employers, and pro-life insurance companies to finance abortions against their beliefs. The Hill reported the investigations without editorial framing. Bloomberg Law confirmed the scope and noted that each state will have 20 days to respond before any enforcement action begins.

Pro-choice groups and attorneys general in several of the named states told reporters the investigations were an attack on state authority to regulate insurance and protect patients. California's attorney general called the Weldon Amendment interpretation "a deliberate distortion" of federal law intended to make abortion inaccessible by enabling any insurer to exclude coverage. Human Rights Watch released a separate report on March 6 documenting what it called preventable deaths resulting from abortion restrictions, noting that the new HHS enforcement posture compounds existing barriers to care.
