This Amicus Curiae Brief is respectfully filed by the undersigned members of the United States Senate Committee on Commerce, Science, and Transportation (“Committee”). Acting in our capacity on behalf of the United States government, we may file this Brief pursuant to Fed. R. App. P. 29(a). The Committee exercises oversight responsibility for both the Federal Trade Commission (“FTC”) and the Federal Communications Commission (“FCC”). With the respect owed to a co-equal branch of government, we file this Brief to share with the Court our strongly-held views regarding the constitutional law issues in contest in this appeal and the vital public policy interests served by the national Do-Not-Call Registry.
