A new investigation by Pulitzer-Prize winning journalist Maria Hinojosa looks at reproductive rights in El Salvador, which has one of the world’s most restrictive anti-abortion laws and has imprisoned women who suffered obstetric emergencies like miscarriages or stillbirths.

While exact numbers are difficult to ascertain, one woman who spent time in prison in El Salvador for a miscarriage estimated “that 90% of the women who are in prison in El Salvador are in prison for this,” says Hinojosa.

Hinojosa also cautions that a version of El Salvador’s law could make its way to the United States as states pass more abortion bans following the end of Roe v. Wade.
