Jill Biden debuts cast at State of the Union

Second lady Jill Biden had an unexpected accessory for the State of the Union on Tuesday: a cast. 

Biden slipped and fell last week, breaking her left wrist, a White House aide said in an email. 

The vice president's wife, who teaches at a local community college and is an avid runner, is expected to be wearing the cast for the next six weeks, the aide said.
