View Comments Rubia Mabel Morales-Alfaro, an asylum seeker from El Salvador, miscarried In January 2018 after being placed behind bars in a privately run immigration detention center in California while in custody of U.S. Immigration and Customs Enforcement. Morales-Alfaro was one of several dozen women who miscarried after being placed in immigration detention centers under a Trump-era policy that critics said was aimed at deterring undocumented pregnant women from coming to the U.S. But under a new Biden administration policy, ICE will for the most part no longer arrest and detain pregnant women, postpartum women and women who are nursing.
