Barrett, Walker campaign over holiday weekend - WKOW 27: Madison, WI Breaking News, Weather and Sports

WEST ALLIS (WKOW) -- Even with the Memorial Day holiday weekend, the candidates in the race for governor are hot on the campaign trail.

Milwaukee Mayor Tom Barrett shook hands with potential voters at a church festival in West Allis on Sunday.

Barrett continued to call out Gov. Scott Walker, asking him to reveal more about his role in Milwaukee County's John Doe investigation.

"The refusal to say who is paying your personal legal bills that go to criminal defense attorneys raises some very serious questions," Barrett said of Walker.

Barrett has also asked Walker to release emails in connection with the investigation.

The governor has said he's not the target of the investigation. Walker has not been charged in connection with the case.

Meantime, Gov. Walker spent time Sunday in Delavan, the town where he grew up.

Walker spoke at a local firehouse and later criticized Barrett for not having a plan for the future.

"It's been what 46 days since the mayor was first asked what he would do and he doesn't have a plan. I think that's because his plan is just to attack me. That's not a way to move the state forward, that's a way to move the state backward," said Walker.

Walker and Barrett will meet for the second time in a debate on Thursday, May 31 at 9 p.m. on WKOW.
