WASHINGTON -- The indictment of Sen. Bob Menendez (D-N.J.) on public corruption charges is the first bribery case involving the use of corporate political spending to support a candidate since the Supreme Court’s 2010 Citizens United decision allowed corporations to do just that. Justice Anthony Kennedy declared in the 5-4 majority opinion that corporations should be free to spend unlimited sums on independent political activities since “independent expenditures, including those made by corporations, do not give rise to corruption or the appearance of corruption.” Those making independent expenditures “may have influence over or access to elected officials,” but that “does not mean those officials are corrupt,” Kennedy wrote. The Department of Justice begs to differ. Menendez’s indictment on Wednesday specifically ties two $300,000 contributions from Dr. Salomon Melgen’s Vitreo-Retinal Consultants to an officially independent super PAC -- donations that were earmarked for Menendez’s 2012 re-election effort -- to actions that the senator took on behalf of Melgen’s business interests. This is exactly the kind of behavior that Kennedy could not fathom happening.
