And it’s still up in the air whether former congresswoman Gabrielle Giffords (D-Ariz.) will make an appearance at the Democratic convention in Charlotte.

In an e-mail message Friday, Giffords spokesperson Hayley Zachary said that the former congresswoman and her husband, astronaut Mark Kelly, have not yet made a decision on whether they’ll attend the convention.
