Women’s Health Protection Act of 2025
Sponsor Tammy Baldwin (D). Original cosponsor. 46 cosponsors. S. 2150 on Congress.gov
Introduced
Women's Health Protection Act of 2025
This bill prohibits governmental restrictions on the provision of, and access to, abortion services.
Before fetal viability, governments may not restrict providers from
• using particular abortion procedures or drugs,
• offering abortion services via telemedicine, or
• immediately providing abortion services if delaying risks the patient's health.
Furthermore, governments may not require providers to
• perform unnecessary medical procedures,
• provide medically inaccurate information, or
• comply with credentialing or other conditions that do not apply to providers who offer medically comparable services to abortions.
Additionally, governments may not require patients to make medically unnecessary in-person visits before receiving abortion services or disclose their reasons for obtaining services.
After fetal viability, governments may not restrict providers from performing abortions when necessary to protect a patient's life and health. The same provisions that apply to abortions before viability also apply to necessary abortions after viability. Additionally, states may authorize post-viability abortions in circumstances beyond those that the bill considers necessary.
Further, the bill recognizes an individual's right to interstate travel, including for abortion services.
The bill also prohibits governments from implementing measures that are similar to those restricted by the bill or that otherwise target and impede access to abortion services, unless the measure significantly advances the safety of abortion services or health of patients and cannot be achieved through less restrictive means.
The Department of Justice, individuals, or providers may sue states or government officials to enforce this bill, regardless of certain immunity that would otherwise apply.

Savings Opportunity and Affordable Repayment Act
This bill creates a new income-driven repayment plan for student loans called the Savings Opportunity and Affordable Repayment (SOAR) plan. The SOAR plan has similar provisions to, but further expands on, the Department of Education's (ED's) final rule published on July 10, 2023, that created the Saving on a Valuable Education (SAVE) plan. The SAVE plan was blocked by federal courts.
The bill directs ED to carry out a SOAR plan program that complies with specified requirements. The bill allows all federal student loan types to be eligible for repayment under the SOAR plan, including Parent PLUS Loans and Federal Family Education Loans.
Under the SOAR plan, a federal student loan borrower whose income is at or below 250% of the federal poverty level (FPL) has $0 monthly payments. A borrower whose income is over 250% of the FPL pays 5% of their discretionary income on loans obtained for undergraduate study and 10% of their discretionary income for all other outstanding loans (e.g., loans obtained for graduate study).
Additionally, under the SOAR plan, holders of eligible federal student loans (e.g., ED or private lenders) must apply 50% of the borrower's monthly payment toward outstanding principal. The other 50% must be applied in the following order: (1) accrued charges and collection costs on the loan, (2) outstanding interest, and (3) outstanding principal.
ED must forgive any loan balance that remains outstanding after a specified maximum repayment period (e.g., 10 years or 15 years).

Cure Hepatitis C Act of 2025
This bill establishes programs and requirements to provide free medications to treat hepatitis C in certain high-risk or vulnerable populations. It also establishes grants and other resources to support testing and treatment for hepatitis C. The bill provides funding for FY2025 to implement these provisions.
The Department of Health and Human Services (HHS) must enter into a five-year purchasing contract with manufacturers of drugs that treat hepatitis C so that eligible individuals may receive the drugs without cost-sharing. Eligible individuals are those diagnosed with hepatitis C who are (1) enrolled in Medicaid or the Children’s Health Insurance Program (CHIP), (2) confined to federal, state, or local correctional facilities (or were released and began treatment there), (3) uninsured, or (4) receiving health care through the Indian Health Service.
Eligibility is limited to those with specified legal immigration statuses. State Medicaid and CHIP programs and state and local correctional facilities may opt into the program; participation is mandatory for federal correctional facilities and the Indian Health Service.
HHS must award grants to certain entities, including states, public health organizations, and correctional facilities, to support the coordination and provision of screening, treatment, and supportive services for the affected populations.
The bill also allows Medicare beneficiaries to receive hepatitis C drugs without cost-sharing from 2027-2031.
