Here is the opinion.

An excerpt:

In 2004, a Department of Justice investigation into Jack Abramoff’s lobbying team unearthed evidence of corruption so extensive that it ultimately implicated more than twenty public officials, staffers, and lobbyists. Appellant Kevin Ring, once a prominent Washington lobbyist, was one of them. Exposing the dark underbelly of a profession that has long played an important role in American politics, this case probes the boundary between legal lobbying and criminal conduct. Ring was convicted of honest-services fraud, paying an illegal gratuity, and conspiracy relating to his provision of meals, tickets, and other gifts to public officials. On appeal, Ring argues that the district court’s instructions on the honest-services counts misstated the law, that the jury lacked sufficient evidence to find that an “official act” underlay the illegal-gratuity charge, and that the district court ran afoul of Federal Rule of Evidence 403 and the First Amendment when it admitted evidence of his lawful campaign contributions. Although each of these arguments is weighty, we ultimately affirm Ring’s conviction.
