There's a possible challenger for Gabrielle Giffords' congressional seat next year.

Giffords, an Arizona Democrat, is still recovering eight months after being shot in the head in Tucson in January.

She has not announced whether she will seek re-election.

Republican State Senator Frank Antenori is forming an exploratory committee to look into a possible run for the seat.

Antenori says he will make his decision early next year.

Giffords is in her third term in Congress. She has been mentioned as a potential candidate for the U.S. Senate
