WASHINGTON, DC - FEBRUARY 24: Senate Armed Services Committee Chairman John McCain (R-AZ) speaks at a news conference at the U.S. Capitol February 24, 2016 in Washington, DC. The Republican Senators held the conference to speak about President Obama's plan to close the military prison at Guantanamo Bay, Cuba. They called the president's plan 'jibberish,' and said they have tried working with Obama to close the detention camp and move the terrorism suspects held there to federal prisons in the United States but this latest proposal is not the way forward.
