Separation 815 refers to the separation of a child from their parent or guardian at the US-Mexico border as part of the Trump administration's "zero tolerance" immigration policy. This policy resulted in thousands of children being separated from their families and placed in detention centers while their parents were prosecuted for illegal entry into the United States. The policy was widely criticized for its inhumane treatment of migrant families and the trauma it caused to children. **
