It's smooth sailing for Secretary of State nominee John Kerry.  In a confirmation hearing, the Massachusetts Democrat said the U.S. will continue seeking a diplomatic solution to the Iranian nuclear crisis.

Senator Kerry also said American leadership is vital in a complicated and increasingly dangerous world.  Kerry's opening statement was interrupted by a woman protesting U.S. policies in the Middle East.  Kerry has chaired the Senate Foreign Relations Committee since 2009, but he took the witness chair for his confirmation hearing.  If confirmed by the full Senate, Kerry will replace Secretary of State Hillary Clinton.  Clinton is stepping down after four years as the nation's top diplomat.
