For months now, the Obama administration has promised to reveal more about America's secret drone program, and today could be the day. The president will speak this afternoon at the National Defense University, and he's planning to discuss America's fight against terrorism. He is expected to address everything from drones to the prison at Guantanamo Bay.
For the first time, the U.S. government has acknowledged killing four American citizens in lethal drone strikes far outside traditional battlefields, confirming information that had been widely known but has only recently been unclassified under orders of the president.
