Dressing like detainees, demonstrators asked President Obama to fulfill his promise "to expedite releases from Guantanamo and to make public the full US Senate Torture Report." /CFP Photo

In fact, Obama even signed an executive order stating that Guantánamo Detention Camp would be closed within the year in 2009, but it was not passed by US Congress. /CFP Photo

As President-elect Donald Trump and his cabinet have advocated keeping the detention facility open, Democrat legislators have written to Obama asking him to make a last-ditch effort to shut it down once and for all. /CFP Photo
