“My family and I are shocked and saddened to learn of the tragic shooting of my friend Congresswoman Gabrielle Gifford and members of her staff. Gabbie is a wonderful representative who works in a bi-partisan fashion for her constituents,” said Rep. Charles Djou (R-Hawaii), who worked alongside Giffords on the House Armed Services Committee. “I will always remember Gabbie for reaching out to Republicans and Democrats alike to find solutions toward bringing down Federal spending and establishing a strong national defense. My heart goes out to Rep. Gifford’s family and the families of her staff on this tragic day.”
"Wendy and I join all other Louisianians in praying urgently and fervently for Congresswoman Giffords and those others who were shot at her town hall meeting," said Sen. David Vitter (R-La.) in a statement. "This is a horrible, despicable attack on good people and on our very democracy."
Giffords was hosting a "Congress in Your Corner" event in front of a Tucson grocery store, when a man walked up and began firing. Several members of Giffords's staff were reportedly among the wounded. The gunman is reportedly in custody.
In April, Giffords supported Rep. Raúl Grijalva (D-Ariz.) after he had to close two offices, including one in Tucson, after he and his staff received threats following his call for a boycott of Arizona businesses in opposition to the state's controversial immigration law.
"I am deeply troubled about reports that Congressman Grijalva and members of his staff have been subjected to death threats," she said in an April 23 statement. "This is not how we, as Americans, express our political differences. "Intimidation has no place in our representative democracy. Such acts only make it more difficult for us to resolve our differences."
Rep. Trent Franks (R-Ariz.) told MSNBC that "there is no way you can put a rational analysis" on the shooting.
"To try and analyze it politically seems even further beyond the pale," he said.
