OPINION
Defendants Bernard Altshuler, Jeffrey Riddle, and Lavance Turnage were convicted by a jury of RICO, RICO conspiracy (18 U.S.C. § 1962(c) & (d)), and conducting an illegal gambling business (18 U.S.C. § 1955), and Riddle and Turnage of committing a violent crime in furtherance of racketeering (18 U.S.C. § 1959). They appeal on several grounds. They argue that the district court erred when it permitted them to be absent during voir dire, and they attack their RICO and violent crime convictions on the grounds that there was an insufficient connection with interstate commerce. They also claim that the evidence was insufficient to support certain counts against them and that the district court erred when it allowed the testimony of a witness after the government had concluded a plea bargain with him, when it did not give a conspiracy withdrawal jury instruction, and when it sentenced them without presentenee reports. We affirm the district court.
Because resolution of defendants’ issues concerning their voir dire absence and the interstate commerce requirements may have precedential value, those issues will be addressed below. The remaining issues raised by defendants are addressed in an unpublished appendix to this opinion.
*532 I.
This is a case about three actors in the Lenine Strollo branch of La Cosa Nostra (LCN) in Youngstown, Ohio. Strollo ran several types of gambling in the enterprise, including a numbers lottery and dice games, some of which were played after-hours at several establishments, mainly Sharkey’s; Jeff, Butch, and Jeff’s; and the Greek Coffee House. These games had operated in Campbell, Ohio, since at least the 1950s, and Strollo became more involved as his political influence in the community grew, until he gained sole control after his release from prison in 1991.
Strollo came to rely on defendant Altsh-uler and another associate named Lawrence Garono in the gambling enterprise. Altshuler ran or supervised most dice games and “stag” parties (games to raise money for a particular cause or event) when he was not in prison, and in the mid 1990s when he was released from prison, Altshuler took control of the ailing gambling business, in part because he suggested he would be able to attract African American drug dealers to the tables. To assist him, Altshuler recruited Riddle and Turnage, who were accepted in the drug dealing community. Together they converted Sharkey’s into a nightclub with a craps game, but the undertaking failed. They had more success with gambling at the restaurant called Jeff, Butch, and Jeffs.
While Strollo built his business, Ernie Biondillo, as a self-designated successor to Strollo’s murdered rival, began to conduct gaming events. Strollo felt that he was not getting his fair share, and he decided to kill Biondillo, delegating the task to Garono and then to Altshuler, who gave the job to Riddle. Riddle in turn involved Turnage. Riddle, Turnage, and another associate, George Wilkins, surveilled Bion-dillo and set out one day with guns to kill him; their efforts came to naught when they could not find Biondillo. Riddle subsequently decided he should not be present at the shooting and found a substitute; Turnage, Wilkins, and the substitute met on June 3, 1996, blocked off Biondillo’s car, and shot and killed him.
Members of the enterprise had been enjoying a certain amount of protection from the Mahoning County prosecutor, who unexpectedly lost the election in 1996 to a former police officer named Paul Gains. In light of several pending cases against enterprise members, including a case against Turnage, Strollo’s contact with the prosecutor’s office stated that the only solution was to kill Gains before he assumed office. Strollo passed the word on to Altshuler, who replied, “We’ll take care of it.” Riddle enlisted Turnage and Wilkins, and in October 1996, the trio went to find Gains at a restaurant in Youngstown to kill him; they had to abandon their plan, however, when they found the area full of police. Turnage gave up on having his case fixed, pleaded guilty to robbery, and went to jail. Riddle then recruited two other men to kill Gains, but they bungled the attempt, leaving Gains wounded but alive.
On December 10, 1997, the government filed an indictment against Strollo and nineteen of his associates, later replaced by a superseding indictment against thirteen defendants. The indictment charged Altshuler, Riddle, and Turnage with violations of 18 U.S.C. § 1962(c) and (d) (RICO) and § 1955 (illegal gambling business), and Riddle and Turnage with violation of 18 U.S.C. § 1959 (violent crime in aid of racketeering).
On December 2, 1998, in a pretrial conference, the parties requested the use of a juror questionnaire. The government asked for an anonymous jury, and Strollo’s counsel asked that all potential jurors be *533 questioned individually in the court’s chambers. The court noted that United States Marshals would have to accompany defendants wherever they went, and the Marshals’ presence in the court’s chambers might prejudice defendants by suggesting to potential jurors that defendants were dangerous. Counsel responded that it would be in defendants’ interest to waive their right to be present in order to preserve the benefit of individual questioning without the potential prejudice of the Marshals’ security. The court agreed and instructed the lawyers to tell the court in writing by January 7, 1999, if the defendants objected to this procedure. There were no objections, and at a February 11, 1999, meeting, defense counsel discussed the proposed voir dire procedure with their clients, at the court’s request, in a holding cell and reported to the court that defendants wished to proceed as agreed. The court issued a written order confirming the waiver.
The prospective jurors then completed under oath a questionnaire of forty-six pages, developed with the input of defense counsel. Counsel agreed to strike a total of sixty-six jurors for cause on the basis of the questionnaires, which were available to defendants during the screening process.
On February 23, 1999, the court began individually questioning the remaining jurors in chambers, one by one, with defense counsel present; the individual voir dire process lasted for three days. Defendants were present in the courthouse on the morning of February 23, but at the start of the afternoon session on that day, defense counsel indicated to the court that defendants requested permission to return to jail until the final stages of the jury selection process. The court, after confirming with counsel defendants’ waiver of their right to be in the courthouse, granted defendants’ request. On March 1, defendants returned to the courtroom for the exercise of peremptory challenges. These challenges were exercised in side-bar conferences in the open courtroom, where defendants were present.
During the screening of the jurors, the government had concluded a plea agreement with Strollo that gave him twelve to fifteen years in prison in exchange for his testimony against the others, and dropped a forfeiture charge in the amount of ten million dollars, plus various properties. The trial began on March 1, 1999, and Strollo fulfilled his bargain by testifying. On March 12, 1999, Altshuler, Riddle, and Turnage were convicted on all counts and sentenced to life imprisonment. After the jury verdict, the court did not order a presentence report, stating that it had adequate information already from previous proceedings. The court offered to sentence the defendants the following week, but defense counsel agreed to do the sentencing that day. The court gave the counsel time to get the defendants’ consent to the sentencing procedure, and counsel made no objections. Defendants were sentenced to life imprisonment without release, with a five-year sentence for illegal gambling to run concurrently. Defendants appeal their convictions and sentences.
II.
A. Voir Dire
Defendants argue that they did not effectively waive their right to be present during voir dire because they did not waive the right in person before the trial court. Defendants are essentially asserting that a trial court must engage a defendant in an on-the-record colloquy before allowing the defendant to absent himself from voir dire, and that failure to do so is a fundamental structural error. We decline to so hold.
*534
A criminal defendant has a constitutional right to be “present at all stages of the trial where his absence might frustrate the fairness of the proceedings[.]”
Faretta v. California,
The right to be present may be waived. Rule 43 allows the court to consider the defendant to have waived the right to be present if the defendant has been initially present and then voluntarily leaves after the trial has commenced, “whether or not the defendant has been informed by the court of the obligation to remain during the trial.” Fed.R.Crim.P. 43(b). Defendants attempt to avoid the conclusion that they waived their right when they consented to the use of questionnaires and requested to leave the courthouse during voir dire by saying that waiver by their counsel was not effective as their waiver. This court has, however, held otherwise. In
United States v. Gallo,
Of course the waiver of this right, as with other constitutional rights, must be knowing and voluntary.
Johnson v. Zerbst,
In this case, defense counsel suggested defendants’ absence, and the court allowed the waiver only after it instructed defense counsel to consult with their clients and then received assurance from defense counsel that the defendants waived their right to be present. To hold that such a waiver of a defendant’s voir dire presence would be effective only after an on-the-record colloquy with the defendant would *535 create a burdensome and impractical rule. Indeed, such a rule would effectively stop the proceedings whenever a defendant refused to return to court. We hold that defendants’ waiver through their counsel of their right to be present during voir dire was effective.
Even if the waiver were not effective, the right to be present at voir dire is not one of those structural rights whose violation constitutes per se error. Rather, there must be prejudice in the absence to warrant reversal.
See Gibbs,
B. Interstate Commerce
Altshuler and Riddle claim that several counts of their conviction should be reversed because the government did not sufficiently establish a link with interstate commerce. Specifically, they argue that the court lacked subject matter jurisdiction to convict them under 18 U.S.C. § 1962 (RICO) and 18 U.S.C. § 1955 (gambling), and Riddle under 18 U.S.C. § 1959 (violence in furtherance of racketeering)
1
because the government did not show a substantial effect on interstate commerce. Defendants raise their interstate commerce argument for the first time on appeal. The claim may only be reviewed for plain error.
See United States v. Gaydos,
Defendants err in asserting that the interstate commerce argument goes to the court’s subject matter jurisdiction.
*536
This court has explained that the interstate commerce requirement, while referred to as a “jurisdictional” element, does not affect subject matter jurisdiction, that is, the court’s power to hear a case. Rather, a claim of an insufficient connection to interstate commerce is a challenge to one of the elements of the government’s case and is therefore considered a claim about the sufficiency of the evidence.
See United States v. Degan,
In attacking the statutes, defendants rely on the Supreme Court’s opinion in
United States v. Lopez,
1. 18 U.S.C. § 1962 (RICO) (Altshuler and Riddle)
Altshuler and Riddle argue that their RICO convictions under 18 U.S.C. § 1962(c) and (d) were invalid because the government was obliged under Lopez to show a substantial effect on interstate commerce, and it failed to do so, alleging only an intrastate enterprise. Section 1962(c) states that
[i]t shall be unlawful for any person employed by or associated with any enterprise engaged in, or the activities of which affect, interstate or foreign commerce, to conduct or participate, directly or indirectly, in the conduct of such enterprise’s affairs through a pattern of racketeering activity or collection of unlawful debt.
18 U.S.C. § 1962(c). Subsection (d) makes it a crime to conspire to violate (c). Because the statute contains a jurisdictional requirement (the enterprise must be engaged in or affect commerce), it is not controlled by
Lopez,
and, according to the Supreme Court, when a RICO enterprise is “engaged in” interstate commerce, the government does not need to show that the enterprise’s effect on commerce is “substantial.”
United States v. Robertson, 514
U.S. 669, 671-72,
Since the Youngstown enterprise here is not “directly engaged in the production, distribution, or acquisition of goods or services in interstate commerce,”
id.
at 672,
We have found a de minimis connection to interstate commerce to be sufficient under similar statutes after
Lopez. See United States v. Ables,
We hold that a de minimis connection suffices for a RICO enterprise that “affects” interstate commerce. The question then is whether the government has met that burden in this case. The Ohio-based enterprise here purchased Pennsylvania lottery tickets to protect against losses in the illegal gambling business; the members sold in Pennsylvania a ring taken from the Youngstown murder victim Biondillo; the enterprise extorted money from a victim who sold fireworks in New York; and the government alleged that the Pittsburgh mafia family was involved in the enterprise (although all of those charged were Ohio residents). Given the low threshold for a de minimis interstate commerce connection, the requirement has been met in this case.
Cf. United States v. Mills,
*538 2. 18 U.S.C. § 1959 (Violent Crimes in Aid of Racketeering) (Riddle)
Riddle claims that 18 U.S.C. § 1959 is directly controlled by Lopez and that his conviction is invalid because the basis for his § 1959 conviction-the murder of Bion-dillo — had no connection with interstate commerce. The government counters that § 1959 expressly contains jurisdictional elements, thus distinguishing it from Lopez.
The statute governing violent crimes in aid of racketeering activity states:
Whoever, as consideration for the receipt of, or as consideration for a promise or agreement to pay, anything of pecuniary value from an enterprise engaged in racketeering activity, or for the purpose of gaining entrance to or maintaining or increasing position in an enterprise engaged in racketeering activity, murders, kidnaps, maims, assaults with a dangerous weapon, commits assault resulting in serious bodily injury upon, or threatens to commit a crime of violence against any individual in violation of the laws of any State or the United States, or attempts or conspires so to do, shall be punished [according to the sentences that follow].
18 U.S.C. § 1959(a). The statute defines “enterprise” as an entity which is “engaged in, or the activities of which affect, interstate or foreign commerce.” 18 U.S.C. § 1959(b)(2).
We agree with the government that the jurisdictional provision in the enterprise definition distinguishes the statute from
Lopez,
but this court has not yet determined what degree of connection to interstate commerce is required under § 1959. The courts of appeals for other circuits have applied the de minimis standard for the underlying RICO violation without requiring the violent act to have a connection with interstate commerce. In
United States v. Gray,
The Court of Appeals for the Second Circuit also affirmed a § 1959 conviction for murders without requiring the murders to impact interstate commerce. Instead, the court required the predicate act (murder) to “bear a strong relationship to racketeering activity that affects interstate commerce[.]”
United States v. Mapp,
3. 18 U.S.C. § 1955 (Illegal Gambling Business) (Altshuler and Riddle)
This court has examined 18 U.S.C. § 1955 after
Lopez
and found it to
*539
be a valid exercise of congressional Commerce Clause power.
United States v. Wall,
III.
For the foregoing reasons, the rulings of the district court with respect to defendants’ voir dire absence and the interstate commerce elements of 18 U.S.C. §§ 1962, 1955, and 1959 are affirmed.
Notes
. Altshuler was not convicted under 18 U.S.C. § 1959.
