Assembly committee OKs investigation into John Doe leaks

(AP) — The state Assembly has authorized Attorney General Brad Schimel to investigate how evidence collected during a secret investigation into Republican Gov. Scott Walker's campaign was leaked to a newspaper.

The state Supreme Court said in its ruling halting the probe that such coordination is legal as long as it doesn't become express advocacy, a political term for advertising that specifically asks voters to defeat or elect a candidate.

The leaked documents showed how Walker's top campaign adviser was coordinating with the group Club for Growth on how to spend the millions Walker was raising to help himself and Republican senators win 2011 and 2012 recall campaigns.
