Gov. Jan Brewer says she will call special primary and general elections for Gabrielle Giffords' seat in Congress after Giffords' resignation takes effect later this week.

Giffords announced Sunday via Youtube video that she will resign because she wants to work more toward recovery from last year's gunshot wound through the head.

The winner of the special election will have to run for re-election in the fall if he or she wants to serve a full term starting in 2013. Brewer's office spokesman said the special primary election needs to be held within 80 to 90 days of the official resignation, which would likely be in April, putting the special general election in June. The filing deadline for the regular August primary is in May, so the activity for the regular and special elections will overlap.

One person has expressed interest in the seat, state Sen. Frank Antenori, a Republican from Vail. Antenori said Sunday that he will provide further information this week on what until now has been an exploratory campaign.

Giffords, a Democrat, was first elected to Congress in 2006, and was a few days into her third term when she was shot. She has spent most of the past year in Houston, recovering from the shooting in intensive physical and speech therapy.

In her resignation video, Giffords says she wants to keep working for the good of the state. Some have already begun hinting that her statement was leaving the door open on a future in public office when her recovery is farther along.

“I’m getting better. Every day my spirit is high," Giffords said. "I will return and we will work together for Arizona and this great country."
