MADISON, Wis. (AP) — Likely presidential candidate Wisconsin Republican Gov. Scott Walker is dismissing a report that he helped steer tax credits and eased up on environmental oversight to benefit national hardware chain Menards after its billionaire owner donated $1.5 million to a conservative group. Yahoo News reported Monday that John Menard Jr. gave the money to Wisconsin Club for Growth to help advance Walker’s agenda when he faced a recall election in 2012. The report cites anonymous sources for the donations, which do not have to be disclosed under campaign finance law. Wisconsin Club for Growth attorney David Rivkin issued a statement that did not address the question of whether Menard made the donations. Walker said Tuesday that he hasn’t “engaged in any of that,” before walking away from reporters.
