Splitting with anti-abortion members of his own party, Wisconsin Assembly Speaker Robin Vos has refused to join 48 other states in ensuring that vulnerable women have access to potentially lifesaving care for up to a year after giving birth.

The Wisconsin Senate passed legislation earlier this year that would increase Medicaid postpartum coverage to 12 months. In the state Assembly, 30 Republicans have co-sponsored the legislation, and there is more than enough bipartisan support to pass the bill in that chamber.

But Vos, who has been speaker for nearly 13 years and whose campaign funding decisions are considered key to victory in elections, controls the Assembly. And, according to insiders at the state Capitol, he hasn’t allowed a vote on the Senate bill or the Assembly version, burying it deep in a committee that barely meets: Regulatory Licensing Reform.

Reached by phone, Vos declined to discuss the issue with ProPublica and referred questions to his spokesperson, who then did not respond to calls or emails. Explaining his opposition, Vos once said, “We already have enough welfare in Wisconsin.” And in vowing to never expand Medicaid, he has said the state should reserve the program only for “those who truly need it.”
