It was her first trip home since she was shot in the head at a January political event.

Giffords boarded a private plane late Sunday morning after spending nearly two days in Tucson. Giffords Chief of Staff Pia Carusone tells The Arizona Republic that details of the visit by Giffords and astronaut husband Mark Kelly were being kept private at his request.

Carusone and Giffords spokesman C.J. Karamargin did not immediately respond to calls from The Associated Press.

Giffords was released from a Houston hospital Wednesday and is set to start outpatient therapy. She had been in the rehab facility since late January, a few weeks after the shooting that killed six and wounded 13.
