Rothschild said the group has been looking closely at legislative campaign committees’ finance reports since the Republican-led Legislature and Gov. Scott Walker approved changes to state campaign finance laws in 2015, including allowing corporate contributions to political parties and campaign committees. The changes took effect at the beginning of 2016.


“Corporate donations to campaigns were against the law for more than 100 years, and we vigorously opposed this change in the law. This is an area that is ripe for corruption on all sides,” Rothschild said.

The complaint filed with the state Ethics Commission last month alleges that Wisconsin Progress did $97,340 worth of research work on behalf of the ADCC in the last half of 2016. That could violate a state law limiting donations by corporations to $12,000 per year, the complaint alleges.
