From February 10, 2007 to September 16, 2008, retired General David Petraeus oversaw all coalition forces in Iraq. He was the mastermind behind the counterinsurgency in Iraq and Afghanistan, and served as top commander of U.S. and NATO forces in Afghanistan until July of 2011, when he became director of the CIA. He is arguably one of the most influential military leaders in recent American history. A new biography about General Petraeus comes out this week.

The week was thrown into uncertainty with the death this morning of Sen. Robert Byrd. The New York Times' Marcus Mabry and The Takeaway's Charles Herman, look at that and the rest of the news coming up in the next seven days.
