"We ... encourage you to direct the Department of Defense to stop conducting such large-scale force-feedings and, where force-feeding is medically necessary to save a detainee's life, to observe the protections required at U.S. Bureau of Prisons facilities," Sens. Dianne Feinstein (Calif.) and Dick Durbin (Ill.) wrote in a letter to Obama. "It is our understanding that the U.S. federal prison guidelines for force-feedings include several safeguards and oversight mechanisms that are not in place at Guantanamo Bay."
Feinstein visited Guantanamo with Sen. John McCain (R-Ariz.) earlier this year. She has previously been critical of the force-feeding procedures, which began on a larger scale after a hunger strike began in February.
As of Wednesday, military officials said that 106 low-value detainees were being tracked as hunger strikers, and 45 were on the "enteral feed," or force-feeding, list. Military officials claim many of the detainees will choose to drink a supplement or eat a meal rather than have a tube snaked down their nose and into their stomach.
Some detainees in Guantanamo's Camp Six have been allowed to return to communal living following a lockdown that began after a raid in mid-April.
Feinstein and Durbin said that "the fact that many detainees have remained in legal limbo for more than a decade and have given up hope" was to blame for the hunger strikes. The letter also noted that Defense Secretary Chuck Hagel has yet to respond to a letter Feinstein sent him last month.
"This should be alarming to all of us, and it is imperative that the Administration outline a formal process to permanently close the Guantanamo facility as soon as possible," they wrote. "We look forward to continue working with you to achieve that end.”
