Andy Worthington: As the co-founder of the CloseGuantanamo.org campaign, I say (from New York City, where I am currently, as part of my visit to call for the closure of #Guantanamo on and around the 15th anniversary of the prison’s opening, on Jan.11, “With just five days left of his presidency, I can only ask President Obama to listen to the 40 members of the Congressional Progressive Caucus, including John Lewis, Seth Moulton, John Conyers, Keith Ellison and Barbara Lee, who, in a letter on Jan. 11, wrote, “[W]ith only days before your term ends, we ask that you definitively close the site by rapidly pursuing any and all options within your existing authority to seek lawful disposition of all of the 55 remaining individuals languishing in the camp. Mr. Trump must be deprived of the use of Guantanamo Bay.”
