The Wisconsin Legislature is currently controlled by the GOP and has many abortion rights opponents who consistently bring legislation to the floor that is aimed at politicizing and restricting abortion (or something that explains the overall hostile legistature).
The US Supreme court is poised to overturn or less the rights provided by Roe. They are currently deliberating one case, but there are other cases making their way through the lower courts.
Republicans on the Senate Committee on Government Operations, Legal Review and Consumer Protection passed SB 923, the Texas-inspired bill to ban abortion on a party line vote. The Texas-inspired bill would ban abortions after 6 weeks, before most people even know they are pregnant, and includes a $10,000 bounty reward for people to sue anyone who provides abortion care.
The U.S. Supreme Court heared arguments on Mississippi’s 15-week abortion ban in the case of Dobbs v. Jackson Women’s Health Organization. This is the first direct challenge to Roe v. Wade since Justice Amy Coney Barrett’s confirmation.
If Roe is overturned Wisconsin's 172-year-old criminal abortion ban could immediately go into effect. The law has no exception for rape, incest, or the health of the woman.
