Who Gets to Sit With the First Lady at the State of the Union?

The 2011 State of the Union came just weeks after Arizona Rep. Gabrielle Giffords was shot in Tucson. Michelle invited the following:

• Mark Kelly, Gabby Gifford's husband
• The former military doctor treating Giffords
• John, Dallas, and Roxanna Green, the family of Christina-Taylor Green, the 9-year-old girl killed in the Tucson shooting

The theme of this State of the Union was national unity, and members of Congress decided to sit together, undivided by political party.
