MADISON, Wis. (AP) -- Conservatives have launched recall efforts against two state senators who opposed a bill that would have helped a Florida company open a huge iron mine in northwestern Wisconsin.

The bill would have streamlined Wisconsin's mine permitting process to help Gogebic Taconite open an iron mine just south of Lake Superior. Republicans touted the bill as their signature job-creation legislation this past session.

But Sen. Bob Jauch, a Poplar Democrat, and Sen. Dale Schultz, a Richland Center Republican, opposed the bill and the measure ultimately died in the Senate this month.

Shirl LaBarre of Hayward filed papers with state election officials on Monday authorizing her to start collecting recall signatures against Jauch. Dan Curran of Dodgeville, filed papers authorizing him to start a committee to explore recalling Schultz.
