HARTLAND, Wis. (AP) -- Gov. Scott Walker says he will work against passage of any bill making Wisconsin a right to work state, but he still won't commit to issuing a veto should such a bill pass.

Walker told The Associated Press in an interview Thursday that he won't respond to that hypothetical scenario. He says he will "actively work" to make sure such a bill doesn't pass and he believes it won't based on conversations he's had with Republican leaders in the Legislature.

Walker sponsored a right to work bill when he was a freshman Assembly member in 1993. And talk of him pushing such a bill intensified last week after a video from January 2011 emerged in which he talked about a divide and conquer strategy when taking on public sector unions.
