MADISON, Wis. (AP) – Republican Assembly Speaker Robin Vos says there have been embarrassing mistakes made at the state’s quasi-governmental job-creation agency, but he believes it’s on the right track.  Vos on Tuesday defended work being done by the embattled Wisconsin Economic Development Corp. in light of Democratic calls to create a special committee to ensure WEDC follows the law. A recent audit found numerous instances where WEDC didn’t follow state law.  On Tuesday WKOW-TV in Madison reported that WEDC’s recently hired spokesman owes $36,000 in back taxes. The spokesman resigned Monday after about a month on the job.  Vos says “there’s no doubt that’s an embarrassing situation,” but he doesn’t think consideration of WEDC’s budget should be held up as Democrats want.
