Bivens announces Senate run

Posted: Updated:

The former chairman of the Arizona Democratic Party announced he's running for the U.S. Senate.

Attorney Don Bivens is hoping to win the democratic nomination for retiring Senator Jon Kyl's seat.

Congresswoman Gabrielle Giffords was considered a strong candidate for the Democratic party.

But it's not clear whether she will run.  Bivens says he would not have run if he believed Giffords would still do so.
