Wisconsin Governor Scott Walker (R) may have to deal with another controversy, this time over failing to disclose who contributed to him financially.

According to a report from the progressive campaign group One Wisconsin Now, Walker violated the state's campaign finance laws 1,115 times since 2009.

Wisconsin law requires that a candidate disclose contributions which exceed $100 -- something that Scott Ross, director of One Wisconsin Now, says he repeatedly declined to do.

"Scott Walker has improperly reported well over $500,000 in contributions from inside and outside of Wisconsin," Ross said. "Scott Walker has absolutely no interest in following the campaign finance rules of the state of Wisconsin and we again call for state regulators to address his serial violation of our laws."

The allegations are just the latest in a string of recent scandals for Walker, who found himself making national headlines in 2011 for stripping collective bargaining rights from public sector unions. Just last week, one of his former aides was charged with enticing a child to sexual activity, and a broader investigation into embezzlement was still ongoing.

Walker is currently facing a possible recall election later this year, if his opponents can collect enough petition signatures by January 17th.

Aides to Gov. Walker did not respond to a request for comment at time of this story's publication.
