US Senator Tammy Duckworth wants a federal law to shield women and families who are using in vitro fertilization.

Sen. Duckworth is seeking federal protections after an Alabama Supreme Court decision upended the process in that state. Her efforts failed Wednesday after a Republican Senator from Mississippi objected to the bill and blocked it from passing. Sen. Duckworth says women’s reproductive rights are under attack.

After the ruling, several clinics closed in Alabama. The bill would have federally protected the right to IVF and other fertility treatments.
