Solitary Confinement Soars in U.S. Immigration Detention Under Trump Governance
A new report reveals a dramatic increase in the use of solitary confinement by Immigration and Customs Enforcement (ICE), raising concerns about human rights and detainee well-being.
What Happened: A Surge in Solitary Confinement
The use of solitary confinement in U.S. immigration detention facilities has significantly increased under the current Trump administration. A report published in September 2025 by Physicians for Human Rights (PHR), utilizing federal data and Freedom of Information Act (FOIA) requests, documented at least 10,588 instances of individuals placed in solitary confinement between April 2024 and May 2025.This represents a substantial escalation compared to previous years.
Researchers from Harvard University’s Peeler Immigration Lab and Harvard Law School contributed to the report, lending further credibility to its findings. The data indicates a monthly increase in solitary confinement placements averaging 6.5% from February through may 2025 - a rate more than double that observed between 2018 and 2023, and over six times the rate during the final months of 2024.
Why It Matters: The Psychological Toll and International Standards
Solitary confinement, defined as holding detainees alone for at least 22 hours a day, is widely recognized as a possibly damaging practice. The United Nations considers solitary confinement exceeding 15 consecutive days to be a form of torture. Prolonged isolation can lead to severe psychological distress, including anxiety, depression, hallucinations, and self-harm.
Dr. Katherine Peeler, medical advisor for PHR and assistant professor of pediatrics at Harvard Medical School, expressed concern over the escalating trend, stating, “That was really dismaying.” The report highlights the vulnerability of detainees subjected to this practice, especially those with pre-existing mental health conditions.
ICE’s response and Justifications
In a statement released on Thursday, Tricia McLaughlin, assistant Homeland Security secretary, asserted that ICE prioritizes the safety and security of individuals in its custody. She explained that disciplinary segregation is only implemented after a detainee is found guilty by a disciplinary hearing panel.
McLaughlin also noted that administrative segregation – isolation for 24 hours – is routinely applied to detainees awaiting removal, release, or transfer, citing security concerns and the orderly operation of facilities, as outlined in ICE’s national Detention Standards. However, critics argue that these justifications are often broad and lack transparency.
Data Breakdown: Solitary Confinement Rates
| Period | Average Monthly Increase in Solitary Confinement Placements |
|---|---|
| February – May 2025 (Trump Administration) | 6.5% |
| 2018 - 2023 | 3.2% |
| Final Months of 2024 | 1.0% |
Who is affected? Vulnerable Populations and Due Process Concerns
While ICE states solitary confinement is used for security or to protect at-risk individuals, the report raises concerns about the disproportionate impact on vulnerable populations. ICE defines vulnerable detainees as those with medical or mental health conditions, pregnant women, and LGBTQ+ individuals. However, advocates argue that placing these individuals in solitary confinement exacerbates their vulnerabilities and can be particularly harmful.
Furthermore, concerns exist regarding due process. Detainees may not have adequate legal representation during disciplinary hearings, and the
