Clayton J. Callen

Clayton focuses his practice in the areas of civil litigation and political law. He has litigated a wide range of cases in state and federal courts across the country. This includes extensive litigation experience in cases involving constitutional law, election law, "whistle-blower" claims under the False Claims Act, and products liability, at both the trial court and appellate court levels. In addition to this litigation practice, Clayton also advises clients regarding compliance with increasingly-complex campaign finance laws.
