ICE placed at least 10,588 people in solitary confinement from April 2024 to May 2025, a report found.

Use of solitary confinement in immigration detention is soaring under the Trump administration, according to a report published Wednesday by Physicians for Human Rights using federal data and records obtained through Freedom of Information Act requests.

Immigration and Customs Enforcement placed at least 10,588 people in solitary confinement from April 2024 to May 2025, the report found. Contributors also included experts from Harvard University’s Peeler Immigration Lab and Harvard Law School.

The use of solitary confinement during the first four months of the current Trump administration increased each month, on average, at twice the rate found from 2018 to 2023, researchers found, and more than six times the rate during the last several months of 2024.

“Every month from February through May, which are the full calendar months of the new administration, the number of people placed in solitary in ICE [custody] increased by 6.5%,” said Dr. Katherine Peeler, medical advisor for Physicians for Human Rights and assistant professor of pediatrics at Harvard Medical School. “That was really dismaying.”
