Former Arizona Rep. Gabrielle Giffords, who suffered serious brain injuries in the Tucson shooting, was among the gun-control advocates to appear with President Obama at the White House. Writing in The New York Times, Giffords denounced the Senate opponents of gun reform, saying: “Our democracy’s history is littered with names we neither remember nor celebrate — people who stood in the way of progress while protecting the powerful. On Wednesday, a number of senators voted to join that list.” She added: “I will not rest until we have righted the wrong these senators have done. … We cannot allow the status quo — desperately protected by the gun lobby so that they can make more money by spreading fear and misinformation — to go on.”
