Barber has returned to work for the first time since being seriously injured in the Tucson mass shooting nearly six months ago. Barber was shot in the cheek and thigh during the Jan. 8 attack, which killed six people and injured 13, including Barber and Giffords. The 65-year-old has spent the past six months undergoing extensive physical therapy and coping with the trauma of the shooting. (AP Photo/Allen Breed) The Associated PressWASHINGTON (AP) — Six months after Congresswoman Gabrielle Giffords was shot, the White House says it will propose some new steps on gun safety in the near future.Spokesman Jay Carney isn't giving details for now, but the changes are not expected to be dramatic since Congress is not viewed as open to any new legislation on guns.Instead people involved in talks at the Justice Department expect to see proposals that can be taken through executive action, such as ways to strengthen the background check system that gun sellers use.Activist groups have been disappointed that President Barack Obama hasn't acted more aggressively on gun control after supporting tough measures earlier in his career. It was Obama who pushed after the shooting for effective steps to keep guns from criminals.
