TUCSON, Ariz. — A Republican Arizona state senator says he has formed an exploratory committee to examine a possible run next year for the congressional seat held by Democrat Rep. Gabrielle Giffords.

Sen. Frank Antenori, of Tucson, made extensive public comments last week about the committee but made his formal announcement Monday before a Republican women's group in Tucson.

Giffords is in her third term in Congress but has spent the past eight months recovering from a gunshot wound she suffered during a Jan. 8 shooting.

She hasn't indicated if she'll seek re-election and also has been mentioned as a potential candidate for the U.S. Senate.

Antenori says he won't say whether he's running until January or February after congressional districts are redrawn.
