Congresswoman Giffords communicating
Tucson - A surgeon at the University Medical Centre in Tucson, Arizona, says US Rep Gabrielle Giffords is able to communicate.
Dr Michael Lemole said at a news conference on Sunday that Giffords responded to doctors' commands.
Lemole says the gunshot went through the left side of her head and that surgeons worked to reduce pressure from swelling in the brain by removing bone fragments.
Giffords was shot by a gunman on Saturday as she met with constituents at a Tucson supermarket.
Six others were killed, and 14 wounded, including the member of congress.
