It's a busy week for the State Department.  Yesterday, outgoing Secretary of State Hillary Clinton testified before Congress on the American consulate attack in Benghazi.  Today, Senator John Kerry, Democrat from Massachusetts, faces his Senate colleagues for his secretary of state confirmation hearings.   If these comments from Senator John McCain, a Republican from Arizona, are any indication, it sounds like Kerry might have an easier time than Clinton did. Senator Bob Corker, Republican from Tennessee, seemed to speak for most senators when he  told his home state paper, "I think Kerry probably will sail through, just to be candid." Kim Ghattas, BBC State Department correspondent and author of the upcoming book "The Secretary: A Journey with Hillary Clinton from Beirut to the Heart of American Power," explains how the State Department may change with Kerry at the helm, and discusses President Obama's foreign policy goals in his second term.
