Jimmy Lee Rasco and Marcus Milton were convicted of conspiracy to commit armed bank robbery, armed bank robbery, and carrying and using a firearm during a crime of violence. Rasco was also convicted of possession of a firearm by a convicted felon and, because the armed robbery was his third “serious violent felony,” sentenced to life imprisonment pursuant to 18 U.S.C. § 3559(c), the “three strikes” statute. Rasco challenges his sentence on the grounds that the “three strikes” statute is unconstitutional and inapplicable in this case. We hold that § 3559(c) does not violate either separation of powers or ex post facto principles and that the district court properly applied § 3559(c) to Rasco in this case. We further hold that the district court properly denied Rasco and Milton’s motions for judgment of acquittal or, in the alternative, for a new trial. The judgment of the district court is affirmed in all respects.
I. BACKGROUND
On July 6, 1995, two unidentified black males committed an armed robbery of the Hibernia National Bank on Ellerbe Road in Shreveport, Louisiana, taking approximately $7,300. The two men fled the bank in a Chevrolet Suburban driven by a third black male. Michael G. Moore, Sr. and his son, Michael G. Moore, Jr., were driving by the bank when the Suburban sped out of the bank parking lot in front of their truck. Observing red smoke and money coming out of the Suburban, the Moores followed the vehicle and called 911 from their car telephone. They watched the three men get out of the Suburban and into a Ford Mustang which was later identified as belonging to defendant Jimmy Lee Rasco. The Moores attempted to follow the Mustang but lost the trail. The police found the Mustang abandoned in a wooded area and, shortly thereafter, arrested Vincent West within the perimeter they had established around the vehicle. The police questioned two juveniles, Robert Taylor and Elton Kimble, who were nearby. The youths reported that a black male had offered to buy a bicycle from them with a $100 bill and provided a general description of the man. Based on this description and the use of the Ford Mustang, the police eventually arrested Rasco. Rasco denied any involvement in the case.
A federal grand jury indicted Rasco and West for armed bank robbery, use of a firearm during a crime of violence, and possession of a firearm. On October 3, 1995, the government filed a Notice and Information pursuant to 18 U.S.C. § 3559(c), commonly known as the “three strikes you’re out” provision, which gave notice that Rasco had two prior “serious violent felony” convictions and that he was subject to mandatory life imprisonment if convicted of a third.
West pleaded guilty to the charges in the indictment and agreed to cooperate with the government. On January 10, 1996, the grand jury returned a superseding indictment that charged Rasco and defendant Marcus A. Milton with conspiracy to commit armed bank robbery in violation of 18 U.S.C. §§ 371, 2113(a), 2113(d); armed bank robbery in violation of 18 U.S.C. §§ 2, 2113(a), 2113(d); and carrying and using a firearm during a crime of violence in violation of 18 U.S.C. §§ 2, 924(c). The indictment also charged Rasco with possession of a firearm by a convicted felon in violation of 18 U.S.C. §§ 2, 922(g)(1), 924(e)(1).
The jury convicted Rasco and Milton on all counts. The district court sentenced Rasco to life imprisonment and a consecutive term of sixty months and ordered restitution in the amount of $2436.16 to Hibernia National Bank. Milton was sentenced to three consecutive five-year terms of imprisonment.
Defendants filed motions for judgment of acquittal or, in the alternative, for a new trial. The district court denied their motions. On appeal, Rasco argues that the “three strikes” statute violates separation of powers and ex post facto principles and that *226 one of the two prior convictions relied upon is not a “serious violent felony” and thus not a proper predicate offense under § 3559(c). Rasco and Milton both contend that the district court erred in denying their motions for judgment of acquittal or a new trial, arguing that (1) the evidence was insufficient to support their convictions, (2) the prosecutor made improper comments during closing argument, and (3) mid-trial publicity prejudiced the jury. In connection with his argument concerning trial publicity, Rasco further contends that the district court erred in denying his request for full attorney-conducted voir dire. We conclude that each of these arguments is without merit.
II. DISCUSSION
A. The “Three Strikes” Statute
Congress enacted the “three strikes” statute as part of the Violent Crime Control and Law Enforcement Act of 1994, Pub.L. No. 103-322, 108 Stat. 1796. Codified as 18 U.S.C. § 3559(c), this statute imposes mandatory life imprisonment on a person convicted of a “serious violent felony” in a federal court if
(A) the person has been convicted (and those convictions have become final) on separate prior occasions in a court of the United States or of a State of—
(i) 2 or more serious violent felonies; or
(ii) one or more serious violent felonies
and one or more serious drug offenses; and
(B) each serious violent felony or serious drug offense used as a basis for sentencing under this subsection, other than the first, was committed after the defendant’s conviction of the preceding serious violent felony or serious drug offense.
18 U.S.C. § 3559(c). The statute defines “serious violent felony” to include several enumerated offenses (including robbery pursuant to § 2113) as well as
any other offense punishable by a maximum term of imprisonment of 10 years or more that has as an element the use, attempted use, or threatened use of physical force against the person of another or that, by its nature, involves a substantial risk that physical force against the person of another may be used in the course of committing the offense.
18 U.S.C. § 3559(c)(2)(F). We review the constitutionality of a federal statute and the district court’s interpretation of a statute de novo.
See United States v. Bailey,
Rasco first argues that, by providing for mandatory life imprisonment, § 3559(c) removes sentencing discretion from the court and vests it with the prosecution in violation of the doctrine of separation of powers. Rasco maintains that judicial discretion in sentencing “is essential to preserve the Constitutionally required fundamental fairness of the criminal justice system.” Although the judiciary has exercised varying degrees of discretion in sentencing throughout the history of this country’s criminal justice system, it has done so subject to congressional control. The Supreme Court has stated unequivocally that “Congress has the power to define criminal punishments without giving the courts any sentencing discretion.”
Chapman v. United States,
Rasco next contends that § 3559 violates the Ex Post Facto Clause of the Constitution, which prohibits the imposition of “a greater punishment, than the law annexed to the crime, when committed.”
Calder v. Bull,
The Supreme Court has held that recidivist statutes not unlike that at issue here do not violate the Ex Post Facto Clause.
See Gryger v. Burke,
Rasco argues that even if § 3559(e) is constitutional, it does not apply in this case because his prior conviction for aggravated battery under Louisiana state law is not a “serious violent felony” within the meaning of the statute. As indicated above, § 3559(c) defines “serious violent felony” to include an “offense punishable by a maximum term of imprisonment of 10 years or more that has as an element the use, attempted use, or threatened use of physical force against the person of another.” Rasco contends that aggravated battery is not a “serious” violent felony because it is classified as a “relative felony” rather than an “absolute felony” under Louisiana law. Rasco further contends that aggravated battery is not a “serious violent felony” because the maximum sentence for the offense is “not more than ten years.”
The Louisiana Criminal Code defines “felony” as “any crime for which an offender may be sentenced to death or imprisonment at hard labor.” La.Rev.Stat. Ann. § 14:2(4) (West 1986). The code does not distinguish between “absolute” and “relative” felonies. Aggravated battery is defined as “a battery committed with a dangerous weapon,” and is punishable by imprisonment with or without hard labor for “not more than 10 years.” La.Rev.Stat. Ann. § 14:34 (West 1986). Aggravated battery thus is a felony under Louisiana law and “has as an element the use, attempted use, or threatened use of physical force against the person of another,” as required by § 3559(c). Further, the offense may be punished by ten years in prison, and thus is an “offense punishable by a maximum term of imprisonment of 10 years or more.” 18 U.S.C. § 3559(e)(2)(F)(ii) (emphasis added). We conclude that aggravated battery under Louisiana state law is a “serious violent felony” as defined in § 3559(c)(2)(F)(ii) and that Rasco’s conviction is therefore a *228 proper predicate offense for sentencing pursuant to § 3559(c)(1).
B. Motions for Judgment of Acquittal or New Trial
1. Sufficiency and weight of the evidence
Rasco and Milton argue that the district court should have granted their motions for judgment of acquittal pursuant to Rule 29 of the Federal Rules of Criminal Procedure based on insufficiency of the evidence. 2 They argue in the alternative that the district court should have granted their motions for a new trial pursuant to Rule 33 of the Federal Rules of Criminal Procedure because the verdict was against the weight of the evidence and the interests of justice would be best served by a new trial. 3
We review the district court’s denial of a motion for judgment of acquittal de novo.
United States v. Castaneda-Cantu,
We review the district court’s decision whether to grant a new trial for abuse of discretion.
United States v. Cooks,
Both defendants were convicted of conspiracy to commit bank robbery, bank robbery, and use of a firearm during a crime of violence, and Rasco was convicted of being a felon in possession of a firearm. Neither defendant disputes that the government proved that an armed bank robbery took place at Hibernia National Bank on Ellerbe Road in Shrevepoi't on or about July 6,1995. 4 Rather, Rasco and Milton argue that the evidence adduced at trial was insufficient to link them to the offense.
The government’s key witness was Vincent West, who testified that the day before the robbery he, Rasco, and Milton planned to commit a robbei’y. West testified that on the day of the l'obbery the three men agreed to rob the Hibernia Bank on Ellerbe Road, and that Rasco and Milton, both armed with handguns, committed the robbery while West waited in the Suburban. When presented at trial with pictures taken by bank surveillance cameras, West identified Rasco as the individual standing on the bank counter with a gun in his hand. West stated that he recognized the white face of the watch that Rasco *229 was wearing. In addition, the evidence showed that Kimble and Taylor, the two juveniles questioned by police, identified Ras-co in a photo lineup as the man who had offered to buy the bicycle on the day of the robbery. Taylor identified Rasco at trial as the man he had seen that day.
Without reviewing all of the evidence presented by the government, we note that it is well-established in this circuit that a defendant may be convicted based upon the uncorroborated testimony of a co-conspirator.
United States v. Hernandez,
2. Prosecutor’s remark during closing argument
During his rebuttal argument the prosecutor noted that defense counsel had made reference in closing to a “Deputy Menefee” despite the fact that no “Deputy Menefee” had testified during trial. The prosecutor remarked that the defense could have called Deputy Menefee or another officer who had written a report on the incident but chose not to, and thus was attempting “to make an issue out of non-evidence.” Rasco and Milton contend that this remark was improper and prejudicially affected their substantial rights by shifting the burden of proof to the defense. They argue that the district court should have granted their motions for a new trial on the basis of this prosecutorial misconduct.
Significantly, the prosecutor’s remark was made in response to defense counsel’s reference to an individual who was not a witness in the case. The prosecutor’s remark did not improperly invite the jury to draw an inference from the defense’s failure to call a certain witness, but suggested that the defense was attempting to rely on evidence that had not been introduced. Even assuming that the prosecutor’s comment was improper, Rasco and Milton have made no showing that the comment prejudicially affected their substantial rights. “The test to be applied in cases such as these is well settled: Does the prosecutor’s argument, taken as a whole in the context of the entire case, prejudicially affect substantial rights of the defendant?”
United States v. Corona,
3. Mid-trial publicity
Rasco and Milton contend that mid-trial publicity concerning Rasco’s prior criminal record and the applicability of the “three strikes” provision was inherently prejudicial and the district court abused its discretion by failing to poll the jury on exposure to trial publicity. As “every claim of potential jury prejudice due to publicity must turn upon its own facts,”
United States v. Aragon,
On the first day of the trial, and each day during, The Shreveport Times, the only local newspaper, ran a story in the local/state section containing a brief statement of the status of the trial and a statement that Rasco faced a possible life sentence under the federal “three strikes” provision due to his two prior convictions. During jury selection, the district judge did not question prospective jurors about possible exposure to new accounts of the trial. After the jury had been sworn in and excused for a recess, Rasco’s attorney, Dan Burt, mentioned to the judge that there had been no questioning regarding *230 trial publicity. The following exchange took place:
Mr. Burt: There was no questioning about publicity, and it might be something that could be handled in the back room quietly with no problem.
The Court: Mr. Burt, everything that’s missing, that is fair game for you and Mr. Rasco. We are at the stage of the trial that nothing is curable at this moment. We are going to have to try this case today and tomorrow.
Mr. Burt: I understand.
The Court: ‘And if you think there has been publicity about this ease, I’ll direct them not to read or to listen, nor to talk. That’s a closing instruction at the end of the afternoon normally, and a beginning-instruction.
Mr. Burt: Right, and maybe throw in, “And if you happen to have read something, put it out of your mind.”
The Court: Right.
Mr. Burt: That’s what we would have done on voir dire anyway.
The Court: All right.
As agreed, the court instructed the jury to disregard any publicity about the trial. Nevertheless, during jury deliberations, the jury foreman sent a note to the judge stating that “One of the jurors has mentioned that Rasco is subject to the ‘3 strikes you’re out rule.’ ” Although Rasco had stipulated to a prior conviction for purposes of the count charging him with being a convicted felon in possession of a firearm, no evidence as to the applicability of the “three strikes” statute had been introduced during trial. The judge received the jury’s note in chambers and summoned counsel to discuss an appropriate response. They agreed to resubmit to the jury a photocopy of the second paragraph of Jury Instruction Number 16, which provided:
If a defendant is found guilty, it will be my duty to decide what the punishment will be. You should not be concerned with punishment in any way. It should not enter your consideration or discussion.
In addition, the judge instructed the jury in writing to “[pjlease reread instruction number 16 — second paragraph (see attached).” Rasco’s counsel did not request that the court determine the extent of the jury’s exposure to the trial publicity.
The trial judge has broad discretion in ruling on the issue of prejudice resulting from a jury’s exposure to news articles concerning a trial.
Aragon,
There are a number of facts specific to this case that, taken together, lead us to conclude that the district court did not abuse its discretion in declining to von- dire the jury concerning exposure to trial publicity. First, the three news articles in the record are brief factual accounts of the bank robbery trial that contain little information about Rasco’s prior criminal record. They state that Rasco has “two prior convictions” and is being tried subject to the federal “three strikes you’re out” rule which would mandate a life sentence if Rasco were found guilty. No article in the record indicates the nature or seriousness of Rasco’s prior offenses. Second, the jury was aware that Rasco had at least one prior conviction given the charge of being a convicted felon in possession of a firearm and Rasco’s stipulation to a prior conviction. This mitigates the potential prejudice of news indicating that Rasco in fact had two prior convictions. Moreover, as the district court noted, knowledge by the jury of the applicability of the “three strikes” rule and its mandatory life sentence could have benefitted Rasco in the course of jury deliberations as easily as it could have prejudiced him. Third, counsel for Rasco agreed after the jury was sworn in that instructions to disregard trial publicity would suffice to ensure a fair trial. This was effective trial strategy on the part of defense counsel; insisting on voir due likely would have raised the level of emphasis on Rasco’s prior convictions. Even after learning during deliberations that one juror had knowledge that the *231 “three strikes” rule applied, defense counsel agreed after consultation with the court that reiteration of the instruction to ignore issues of sentencing was an adequate response. Finally, the jury in fact was admonished repeatedly to disregard all media accounts of the trial and to ignore issues of punishment during deliberations.
Rasco and Milton insist that the district court was required to voir dire the jury in light of the mid-trial publicity, citing
Aragon, supra.
In
Aragon,
a drug smuggling case, this court held that the district court abused its discretion in denying defense counsel’s request at the commencement of trial to poll the already-empaneled jury regarding exposure to a highly prejudicial article that appeared that morning in the local paper.
Our cases indicate that whether a district court abuses its discretion in declining to voir dire a jury following mid-trial publicity depends on the specific circumstances of the case. Under the circumstances here, the district court was within its discretion to decline to voir dire the jury and a new trial is not warranted on this ground.
4. Attorney-directed voir dire
Finally, Rasco argues that he was deprived of a fair trial because the district court denied his motion for full attorney-directed voir dire. We review the manner in which the district court conducts voir dire for clear abuse of discretion.
United States v. Rowe,
Rasco claims that examination of potential jurors by defense counsel would have revealed that some of the jurors had knowledge of Rasco’s criminal history as a result of media publicity. Rasco’s counsel, however, suggested at the conclusion of jury selection that the court could handle the publicity issue “in the back room quietly with no problem,” and stated that admonishing the jury to ignore any information that they might have been exposed to was “what we would have done on voir dire anyway.” Furthermore, the requested jury questions that defense counsel submitted to the court before voir dire did not specifically inquire into exposure to media publicity.
The tidal court has broad discretion to determine who will question potential jurors and what questions will be asked.
Rosales-Lopez v. United States,
The court may permit the defendant or the defendant’s attorney and the attorney for the government to conduct the examination of prospective jurors or may itself conduct the examination. In the latter event the court shall permit the defendant or the defendant’s attorney and the attorney for the government to supplement the examination by such further inquiry as it deems proper or shall itself submit to the prospective jurors such additional questions by the parties or their attorneys as it deems proper.
Fed.R.CRIM.P. 24(a) (emphasis added). The district court did not abuse its discretion in its conduct of voir dire in this case.
*232 III. CONCLUSION
We hold that 18 U.S.C. § 3559(c) does not violate separation of powers or ex post facto principles and was properly applied to Rasco in this case. We further hold that the evidence was sufficient to support the convictions of Rasco and Milton and that a new trial is not warranted on the basis of the prosecutor’s remarks during closing argument, mid-trial publicity, or the district court’s conduct of voir dire. The judgment of the district court is AFFIRMED.
