Later this morning, President Obama will deliver a long-awaited policy address in which he's expected to explain new guidelines on the use of unmanned military drones. In addition, he may call, once again, for the closure of the Guantanamo Bay detention camp.

All this comes after the administration admitted for the first time that four Americans had been killed in drone strikes that took place in Yemen and Pakistan.

Michael Hirsh, chief correspondent at National Journal, joins the show for a preview of the President's speech and a look at the debate over the use of drones.
