ICE detention centers are holding thousands more immigrants in solitary confinement than previously reported, with the practice expanding under both the Biden and Trump administrations. Data from Physicians for Human Rights and Harvard University researchers shows vulnerable populations, including those with mental health conditions, are spending an average of over 40 days in solitary confinement. This exceeds the 15-day threshold established by human rights experts. The Trump administration has dramatically increased overall ICE detention capacity while maintaining the expanded use of segregation tactics.
