Republican Senator Lindsey Graham might finally be ready to play nice with the White House on Guantanamo Bay, two months after Obama’s self-imposed deadline to close it passed. But there’s a catch: Graham will help rally Republican support for the camp’s closure, he said Sunday, only if President Obama agrees to backtrack and send alleged Sept. 11 planner Khalid Sheikh Mohammed and others to military tribunals instead of civilian courts. “I don't believe Khalid Sheikh Mohammed robbed a liquor store. He's the mastermind of 9/11,” Graham told CBS’s Face the Nation. “If he's not an enemy combatant, who would be?” Democratic Senator Evan Bayh said that it was a deal worth considering for Obama. "I think the administration gets something, and yet the public gets reassured," he said.
