The Government Accountability Office has found serious performance and oversight challenges at the country's largest Immigration and Customs Enforcement detention facility in Texas, according to a new report.

The facility, identified as Camp East Montana and located at Fort Bliss Army base, experienced multiple incidents between August 2025 and March 2026 that prompted the congressional watchdog investigation. The problems included a security guard losing a loaded weapon and failures to conduct required tuberculosis testing.

During the investigation period, two deaths occurred at the facility that were examined by the Government Accountability Office. The report also documented issues with missing records, medical care failures, and wasteful spending practices.

The facility has faced criticism for waste and unsanitary conditions in addition to the security and medical oversight problems. The detention center houses immigrants in federal custody as part of ICE operations.

The Government Accountability Office's findings highlight ongoing challenges in the oversight and management of immigration detention facilities. The report adds to scrutiny of conditions and practices at facilities used to house immigrants in federal custody.
