SACRAMENTO, Calif. (AP) — California GOP Senate challenger Carly Fiorina is in the hospital to be treated for an infection associated with her reconstructive surgery after breast cancer.

Deborah Bowker, the campaign's chief of staff, says in a statement issued Tuesday that Fiorina was admitted to a hospital and is being treated with antibiotics. The campaign will not say when or where she was admitted.

Fiorina, who is 56, fought breast cancer before her run against Democratic Sen. Barbara Boxer. The former Hewlett-Packard Co. CEO has maintained a busy campaign schedule in the final weeks of the race.

Bowker says Fiorina has canceled Tuesday campaign events in Riverside and Coachella. She says she expects Fiorina to return to the campaign trail soon.
