Eleven Democratic senators said Monday that the Pentagon\u0026#039;s refusal to provide details about its Covid-19 mitigation strategy at Guantanamo Bay, where 40 detainees are currently being held, only bolsters the case for shutting down the U.S. military prison in Cuba.Lawmakers including Sens. Elizabeth Warren (D-Mass.), Bernie Sanders (I-Vt.), Ed Markey (D-Mass.), and Ron Wyden (D-Ore.) denounced the Department of Defense\u0026#039;s response to their earlier letter, in which they demanded to know specifics regarding the government\u0026#039;s plan to keep Covid-19 from spreading in the facility, where a number of medically vulnerable detainees are being held indefinitely.\u0026nbsp;\u0022The Pentagon\u0026#039;s response leaves doubts about the Guantanamo prison\u0026#039;s capacity to protect military personnel and detainees from Covid-19 and is a reminder that the United States should work to responsibly close this facility.\u0022 —Democratic senatorsIn addition to the prison being \u0022inconsistent with our values\u0022 and doing nothing to keep Americans safer, the senators said Monday, the Pentagon\u0026#039;s lack of transparency regarding containment and mitigation methods makes it clear that Guantanamo Bay must no longer be used to detain people captured over the last two decades as part of the so-called \u0022War on Terror,\u0022 the majority of whom have not been charged with a crime.In late May, the senators expressed concern to Defense Secretary Mark Esper about the facility\u0026#039;s ability to provide medical care to detainees who contract Covid-19, given \u0022the serious and deteriorating health conditions of detainees, the deficient infrastructure to care for complex medical needs at the prison facility, and the strict prohibition on detainee transfers to the United States.\u0022The senators\u0026#039; letter came two months after the first case of Covid-19 was reported at the Naval station, when a sailor who was reportedly not involved with prison operations tested positive in late March. Another case was reported in April before the Pentagon ordered the base to stop reporting cases to maintain \u0022operational security.\u0022The Navy announced in March that it was implementing deep-cleaning measures, social distancing guidelines, and limits on group gatherings to prevent the spread of Covid-19. Since then, Matthew Donovan, an undersecretary of defense in charge of personnel and readiness, has also informed Congress that officials at Guantanamo Bay are requiring temperature checks for anyone who enters buildings there and that the prison clinic has six ventilators.\u0026nbsp;Still, the senators wrote in their letter to Esper, \u0022it remains unclear whether the Department\u0026#039;s coronavirus infection control efforts will be enough to protect the health of the 40 detainees at the Guantanamo prison\u0026nbsp;facility, six some of whom are \u0026#039;aging detainees [who] could require specialized treatment for issues such as heart attack, stroke, kidney failure, or even cancer.\u0026#039;\u0022The lawmakers requested\u0026nbsp;specific information regarding procedures in place to address confirmed or possible Covid-19 cases, whether independent medical experts are available, and the status of the Pentagon\u0026#039;s appointment of a chief medical officer at Guantanamo, as required by the National Defense Authorization Act.Donovan replied to the senators\u0026#039; letter last month, offering just four paragraphs assuring them—without any details—that Joint Task Force Guantanamo \u0022has been following a detailed Covid-19 contingency and mitigation plan,\u0022 that some detainees have \u0022medical expert consultants for the purposes of litigation, and that the Pentagon is working to fill the position of chief medical officer at the base.\u0026nbsp;\u0022The Pentagon\u0026#039;s response leaves doubts about the Guantanamo prison\u0026#039;s capacity to protect military personnel and detainees from Covid-19 and is a reminder that the United States should work to responsibly close this facility,\u0022 said the senators Monday.\u0026nbsp;The oldest detainee at Guantanamo Bay will turn 73 this month, and a number of people held there \u0022retain the mental and physical wounds of torture and may be at greater risk of serious medical complications from Covid-19,\u0022 the senators said in their statement.\u0026nbsp;The senators\u0026#039; statement came days after the International Committee of the Red Cross canceled its planned quarterly visit to Guantanamo Bay, citing concerns over the coronavirus pandemic. With the visit canceled, detainees at the facility will go the longest they have since 2002 without confidential discussions with an independent medical officer and the ability to relay messages to family.
