The chief executive of a successful American exporter will have a prime spot on Tuesday night to watch President Barack Obama make the case in his final State of the Union address for a sweeping Asian trade deal he hopes will be part of his legacy. Ronna Rice, CEO of a Greeley, Colorado honey company that ships its sweet product as far as Japan, South Korea and China, will be one of 23 guests in the First Lady’s box to hear the speech in person. Inviting Americans whose stories bring to life the priorities of the White House has long been part of the annual State of the Union ritual.
