KENOSHA, Wis. -

Gov. Scott Walker said he played no role in soliciting donations from a mining company to a key conservative group that ran ads supporting him during the 2012 recall attempt.

The Milwaukee Journal Sentinel reported Walker made the comments Saturday at a Kenosha campaign event.

Court documents released Friday by a federal appeals court show that prosecutors believe Walker solicited donations for conservative group Wisconsin Club for Growth to get around campaign finance limits and disclosure requirements as he fended off the recall attempt.

Walker also said he was not aware of $700,000 donated by Gogebic Taconite to Wisconsin Club to Growth.

Walker said no one should be surprised he backed legislation helpful to the firm since he had long been supportive of easing regulations on mining.
