MADISON, Wis. (AP) — A convoluted legal fight over an investigation that has dogged Wisconsin Gov. Scott Walker for years shows no signs of ending soon. Walker scored a pair of legal wins this week, but the court fight continues and could stretch into the fall and beyond. The first-term Republican is running for re-election against Democrat Mary Burke, a former Trek Bicycle Corp. executive. He also is considering a run for president in 2016. Investigators for nearly two years have been looking into possibly illegal campaign fundraising and coordination involving Walker's 2012 recall campaign and conservative groups. A federal judge twice this week order the probe stopped, saying it violated free-speech rights. Prosecutors were appealing, keeping the case alive even as Walker says he's not being distracted by it.
