MADISON, Wis. (AP) -- Republican state Assembly Speaker Jeff Fitzgerald wants to make it a felony for anyone to sign the same recall petition multiple times.

Fitzgerald on Thursday introduced a bill that would make that a crime. State law already outlaws signing a fake name to a petition or someone else's name.

Under current law, the burden for finding fraudulent signatures rests with those challenging them and not the state elections board which reviews the petitions once submitted.

There are ongoing petition drives to recall Gov. Scott Walker, Lt. Gov. Rebecca Kleefisch and four Republican state senators. Those petitions are all due Jan. 17.

The Legislature is not due to return to work until that day as well, meaning Fitzgerald's bill would not be in place to affect the current recall efforts.
