Biden Says 'Out of Afghanistan in 2014', Administration Disagrees

According to Foreign Policy’s diplomatic blog The Cable (which I recommend, by the way):

Despite statements by Vice President Joe Biden, the State Department is about to begin formal negotiations over the extension of U.S. troops past 2014, a top State Department official said Tuesday.

Last week, U.S. and Afghan negotiators met in Kabul to talk about the Bilateral Security Agreement that will govern the extension of U.S. troops past 2014, when President Barack Obama said the combat mission in Afghanistan will end and the U.S. will complete the transition of the entire country to Afghan government control.

I wonder how this happened to be released just before the debate?
