Rep. Gabrielle Giffords is scheduled to attend her husband's retirement ceremony in Washington.
The Arizona congresswoman, who was shot in January outside a Tucson grocery store, is set to join her husband, Navy Capt. Mark Kelly, at an event Thursday that will be presided over by Vice President Joe Biden.
Giffords' press secretary, Mark Kimble, tells The Associated Press that Giffords will then return to Houston, where she is undergoing rehabilitation therapy.
Giffords stunned colleagues in August when she briefly returned to the Capitol to vote for a bill raising the government's debt ceiling.
Kelly was the commander of the last mission of space shuttle Endeavour in May. He is writing a memoir with his wife that is set to be released Nov. 15.
