That same month, the House of Representatives Homeland Security Committee released a report finding that people detained by ICE are often in poor medical care and that detention centers are using segregation as a threat against immigrants.

ICE has publicly insisted that its detention centers, as well as those operated by private, for-profit corporations, provide all detainees with thorough and adequate medical care. Agency officials have repeatedly said that they take the health and safety of detainees very seriously and that while deaths are “regrettable and always a cause for concern” they are “extremely rare”.
