MADISON-News broke late Wednesday that revealed the reason Scott Walker was so willing to take a phone call from oil tycoon David Koch.

Read the shocking story here.

"Scott Walker has ransomed off the health of Wisconsin and her waterways for Koch Brothers lucre," Democratic Party of Wisconsin Chair Mike Tate said Thursday. "Scott Walker must answer exactly why he is allowing dangerous Koch Brothers phosphorus pollution into our rivers, bays and streams at the same time accepting hundreds of thousands of dollars from these out-of-state tycoons, whose interests clearly do not coincide with the people of Wisconsin. Something here smells."
