By refusing to veto the National Defence Authorisation Act, Obama has allowed the controversial facility to stay open.
Human rights groups are denouncing President Barack Obama's failure to veto a defence bill that will make it far more difficult for him to fulfill his four-year-old pledge to close the Guantanamo detention facility this year.
Obama had threatened to veto the 2013 National Defense Authorization Act (NDAA) precisely because it renewed, among other things, Congressional restrictions which he said were intended to "foreclose" his ability to shut down the notorious prison, which has been used for the past 11 years to detain suspected foreign terrorists.
