MADISON, Wis. (AP) -- Gov. Scott Walker says he still doesn't know whether his proposal for bolstering investment capital in Wisconsin will be included in his budget or put forward in a separate bill for the Legislature to consider.

Walker said at a Thursday meeting of economic development leaders from around the state that he's still working on details of the venture capital plan. He says the exact size of the fund is still being determined and how best to leverage state tax dollars.

Investors have long complained about the lack of money available for startup businesses in Wisconsin.

A $400 million venture capital plan was put forward in 2011, but it died amid disagreement among politicians and special interest groups about how the program would work.
