Milwaukee Journal-Sentinel: "Citing leaked documents gathered during a now-shuttered investigation into the governor's campaign, the Guardian U.S., an arm of the British newspaper, reported that Harold Simmons, owner of NL Industries, a producer of the lead formerly used in paint, made three donations totaling $750,000 to the Wisconsin Club for Growth between April 2011 and January 2012.
"Simmons' donations were made before and after Republicans approved two laws helpful to the industry — one in January 2011 and the other in June 2013. The 2013 measure was inserted in a budget bill in the middle of the night despite warnings about its constitutionality."
"Simmons' contributions mirror a $700,000 donation from mining firm Gogebic Taconite to Wisconsin Club for Growth around the same time, a donation that was earlier disclosed in court records. After that contribution, the GOP-controlled Legislature and Walker approved legislation aimed at streamlining regulations for an iron ore mine in northern Wisconsin."
