Republican congressional and senatorial committees ask the U.S. Supreme Court to pause a ruling that limits discounted “lowest unit rate” TV advertising to candidates, not political parties or related committees, ahead of the November midterms. The request is filed as an emergency application, with the committees arguing they have been booking cheaper ad slots that broadcasters are now canceling.

The dispute stems from an FCC interpretation issued earlier in the year after the Communications Act’s “Lowest Unit Rate” rule. A three-judge panel of the U.S. Court of Appeals for the Fourth Circuit ruled the discounted rate applies only to legally qualified candidates, not to coordinated party spending or committee ads that involve non-candidate members. Democrats running for office—identified by outlets as Kristen McDonald Rivet, Sherrod Brown, Jon Ossoff, and Roy Cooper—were the challengers.

Outlets also report that the Trump administration supports the Supreme Court application. Solicitor General D. John Sauer argues the FCC notice does not grant one side preferential treatment and that the challengers’ challenge is procedurally improper. The Supreme Court is expected to act quickly given the statutory election-time window for broadcasters’ pricing.
