The opinion in United States v. Emmons is here. Alison Lundergan Grimes from Kentucky challenged Mitch McConnell in 2014 for a U.S. Senate seat. Her father (who ran a closely-held business) and a family friend were found guilty of making unlawful corporate contributions to the campaign. The Sixth Circuit found that “intrafamilial contributions” could be constitutionally regulated (relying on Buckley v. Valeo), and that funds from a closely-held, family run corporation could be constitutionally regulated (distinguishing Citizens United v. FEC: “given that intrafamilial contributions can be constitutionally restricted, there is no concern regarding speech discrimination based on the ‘speaker’s corporate identity,’ and no basis to treat these contributions any differently from other corporate contributions, or contributions generally for that matter”).
