MADISON, Wis. (AP) -- Three Democrats looking to challenge Republican state senators in this spring's recall elections have filed nomination signatures.

Challengers had until the end of the day Tuesday to file at least 400 signatures with the state Government Accountability Board to get their name on the ballot.

As of mid-afternoon, Lori Compas had filed signatures to challenge Senate Majority Leader Scott Fitzgerald, a Juneau Republican, and John Lehman had filed against Sen. Van Wanggaard, a Racine Republican.

State Reps. Donna Seidel, a Wausau Democrat, and Jerry Petrowski, a Marathon Republican, filed to run for former Republican Sen. Pam Galloway's seat. Democrats forced Galloway into a recall but she resigned rather than defend her seat, leaving it open.

The recall elections have been scheduled for May 8 and June 5.
