Interesting development in WI John Doe investigation reported by the Milwaukee Journal-Sentinel:

The prosecutor who headed an investigation into Gov. Scott Walker’s campaign said Friday he had not previously seen some of the probe documents leaked this week, including ones regarding $750,000 in donations from the billionaire owner of a company being sued by people poisoned by lead paint.

The donations by Harold Simmons of NL Industries were made before and after Walker and Republicans in the Legislature passed laws making it tougher for victims to win such lawsuits.

“I have no recollection of ever seeing anything concerning that,” special prosecutor Francis Schmitz said.

His comments renew questions about how the Guardian US obtained the records. The U.S. arm of the British newspaper this week posted 1,352 pages of documents about the probe, including the ones about Simmons’ donations.
