MADISON, Wis. (AP) -- Democrat Kathleen Falk is embarking on a statewide tour to tout her campaign against Republican Gov. Scott Walker.

State election officials are still in the process of verifying that at least 540,208 signatures were submitted on petitions seeking Walker's recall from office. Once that is done, an election would be scheduled.

Falk is the only announced Democratic candidate.

She planned a two-day tour of the state that begins Tuesday in Milwaukee and then continues in Green Bay and Wausau.

On Wednesday she plans to be in Eau Claire and La Crosse.

A number of other Democrats are considering getting into the race, but none of them have officially declared yet.
