Marine Corps veteran Adrian Clouatre doesn’t know how to tell his children where their mother went after U.S. Immigration and Customs Enforcement officers detained her last month.

When his nearly 2-year-old son Noah asks for his mother before bed, Clouatre just tells him, “Mama will be back soon.” When his 3-month-old, breastfeeding daughter Lyn is hungry, he gives her a bottle of baby formula instead. He’s worried how his newborn will bond with her mother absent skin-to-skin contact.

His wife, Paola, is one of tens of thousands of people in custody and facing deportation as the Trump administration pushes for immigration officers to arrest 3,000 people a day.
