Bernie Sanders on Tuesday praised President Barack Obama’s proposal to close Guantánamo Bay, noting in a statement that he has supported closing the U.S. military prison in Cuba for years—unlike Hillary Clinton, his rival for the 2016 Democratic presidential nomination.

“I am encouraged to see that the president is sending Congress a plan to shut down the Guantánamo Bay prison. As I have said for years, the prison at Guantánamo must be closed as quickly as possible,” Sanders said Tuesday.
