U.S. Rep. Gabrielle Giffords helped serve a Thanksgiving meal to service members and retirees at a military base in her hometown of Tucson, Ariz. Giffords arrived in the dining hall at Davis-Monthan Air Force Base at midday Thursday wearing a ball cap and an apron with her nickname of “Gabby” sewn on the front. She was accompanied by her retired astronaut husband, Mark Kelly, who also donned an apron. Giffords used only her left hand as she served, a sign that physical damage remains from the injuries she suffered when she was shot in January. Kelly supported her from her left side as she worked the turkey station on the serving line. He served ham. Afterward, she mingled with service members, exchanging pleasantries and mostly one word greetings and responses. Giffords has been undergoing intensive rehabilitation at TIRR Memorial Hermann in Houston as she recovers from a gunshot wound to the head. She was among 19 people shot Jan. 8 as she met with constituents outside a Tucson supermarket. Six people died. … President Barack Obama telephoned 10 U.S. service members stationed abroad to wish them a happy Thanksgiving and praise their military service. Obama made the calls Thursday morning from the Oval Office to two members each from the Air Force, Army, Coast Guard, Marines and Navy who are deployed in support of U.S. operations in Afghanistan and Iraq. Obama has made the Thanksgiving calls each year since becoming president. In a radio address to the nation, the president also asked Americans to remember the men and women in the military who are spending the holiday serving their country overseas. The first family later Thursday was sitting down for a holiday feast including turkey, ham, cornbread stuffing, oyster stuffing, greens, macaroni and cheese, sweet potatoes, green bean casserole and dinner rolls. Dessert selections included banana cream pie, pumpkin pie, sweet potato pie, huckleberry pie and cherry pie.
