On July 27, 2012, CREW along with six other good government groups filed in the U.S. Court of Appeals for the D.C. Circuit an amicus or friend of the court brief in Van Hollen v. FEC. This case involves a challenge to an FEC regulation that allows non-profit 501(c)(3) groups, like Crossroads GPS, and 501(c)(4) groups, like the Chamber of Commerce, to spend millions on electioneering communications without disclosing their donors. The district court struck down the regulation as exceeding the FEC’s authority under the Bipartisan Campaign Reform Act of 2001 (BCRA). That statute requires disclosure of “all contributors” who contribute more than $1,000. CREW’s amicus brief explains how the FEC regulation would lead to massive evasion of BCRA’s requirements and cause the kind of harm BCRA was enacted to prevent.
