U.S. Rep. Gabrielle Giffords has competed two weeks of intensive therapy sessions in North Carolina as she continues to recover from a gunshot wound to the head.

Giffords' office says she returned to Houston on Friday evening and will return to the intensive rehabilitation program at TIRR Memorial Hermann's outpatient facility.

Her staff says the trip to Asheville, N.C., was strictly rehabilitation-related and had been planned for several months. No other specifics on her therapy were given.

Staffers say Giffords arrived in North Carolina on Oct. 23 and began therapy sessions the following day.

Giffords is recovering from a brain injury she suffered Jan. 8 when a gunman opened fire outside a Tucson supermarket where she was meeting constituents. Six people were killed and 13 were wounded, including Giffords.
