Defendants-appellants Frank Chaves (“Chaves”) and Angel Amado Garcia (“Garcia”) appeal their convictions on charges arising from thefts in Florida of goods in interstate commerce. Chaves also appeals his sentence. 1 For the reasons that follow, we *1467 affirm appellants’ .convictions and Chaves’ sentenee.
I. STATEMENT OF THE CASE
A.The April Theft
On April 27, 1989, Luis Guevara, Eduardo Paula, and Orlando Brito stole a truck containing frozen seafood and drove to an abandoned warehouse. There, Guevara stated that he would ask Chaves, who owned a seafood company called J & F Seafood, to dispose of the seafood using one of Chaves’ trucks. Upon Guevara’s request, Chaves left the truck’s key under the front seat.
On April 28, 1989, Guevara, Paula, Brito and Diego Diaz, Jr., picked up Chaves’ truck at J & F Seafood and used the truck to transport part of the stolen seafood from the warehouse to Chaves’ business. Chaves assisted them in unloading the truck’s contents. Later that day,, Chaves went to David Arthur Schlinder, a middleman in the sale of seafood, and offered him “a good deal on lobster tails,” providing a sample case. Schlinder displayed the lobster tails to Henry Torres, a large distributor of seafood in the area. Torres told Schlinder that the lobster tails were stolen and belonged to him. Torres took the sample case and reclaimed the remainder of his seafood from Chaves. Later that day, Guevara and Diaz, Jr., returned to Chaves for payment, but Chaves refused to pay because he had returned the seafood to its rightful owner, Torres. When Guevara and Diaz, Jr., demanded Torres return the seafood, Torres threatened to call the Federal Bureau of Investigation (“FBI”).
The next day, Chaves purchased the remainder of the frozen seafood from Diaz, Jr., and Guevara. Chaves also gave Guevara two bottles of champagne in recognition of Guevara’s lost profits from Torres’ reclamation of his seafood. Later, Chaves brought Schlin-der into a large walk-in freezer at J & F Seafood and told him that the FBI had approached Chaves and that Schlinder should not. speak with them if contacted.
B. The June Theft
In June 1989, another theft of a truck containing frozen seafood occurred. 2 On June 22, 1989, Garcia identified to Paula and Brito the location of some tractor trailers. Four members of the group thereafter stole a tractor trailer loaded with frozen seafood and drove to a nearby warehouse where they set off the trailer’s alarm. Garcia, who had since arrived, assisted them in quieting the alarm. After Garcia and two others left, Chaves was informed that the group had obtained frozen seafood and once again needed his truck.
Garcia and others used Chaves’ truck to deliver part of the seafood to J & F Seafood. On June 24, 1989, Garcia, Paula, and Brito were paid their share of the proceeds of the delivered seafood, and Garcia and Paula were instructed to return to the warehouse to repair the refrigeration unit on the stolen tractor trailer. That evening, Garcia and Paula entered the warehouse and, when they exited, Garcia was carrying bolt cutters. 3 On June 25, 1989, Chaves refused to allow his truck to transport the stolen seafood. On June 26, 1989, Guevara, Paula, and Brito, who had since purchased another truck to transport the seafood, were arrested at the warehouse. 4
C. Procedural Background
On August 4, 1989, á federal grand jury indicted Garcia and six others, including Bri-to but not Chaves, on charges arising out of the June theft. On October 6, 1989, the grand jury issued a superseding indictment replacing Chaves for Brito on charges arising out of the June theft and out of the earlier April theft. 5 Count I charged Chaves, *1468 among others, with conspiracy to steal the April shipment in violation of 18 U.S.C.A. § 371 (West 1966). Count II charged Chaves, among others, with possession of the stolen April shipment in violation of 18 U.S.C.A. § 659 (West 1976) and 18 U.S.C.A. § 2 (West 1969). Count III charged Chaves and Garcia, among others, with conspiracy to steal the June shipment in violation of 18 U.S.C.A. § 371. Count IV charged three non-appellants with theft of the June shipment in violation of 18 U.S.C.A. §§ 2 & 659. Count V charged Chaves, Garcia, and others with possession of the stolen June shipment in violation of 18 U.S.C.A. §§ 2 & 659.
A jury found Chaves guilty of counts I and II, related to the April theft, and not guilty of counts III and IV, related to the June theft. The jury found Garcia guilty of counts III and V, related to the June theft. 6 On May 10, 1990, the district court sentenced Chaves to a twenty-four month term of imprisonment followed by three years of supervised release, as well as restitutory payment of $18,000. The court sentenced Garcia to an eighteen month term of imprisonment followed by three years of supervised release. Chaves and Garcia appealed. 7 Chaves is on bond pending appeal. Garcia is serving his term of supervised release.
II. ANALYSIS
Chaves raises the following claims: (1) the district court improperly limited the cross-examination of Brito, who testified as a government witness; (2) the court erred by amending the jury instructions; (3) the court erroneously added two points to Chaves’ guidelines score for having engaged in relevant conduct that involved more than minimal planning and two additional points for obstruction of justice; and (4) the court abused its discretion by denying Chaves’ motion for a new trial based on newly discovered evidence. Garcia raises the following claims on appeal: (1) the court improperly admitted evidence prejudicial to Garcia; (2) insufficient evidence was adduced at trial to support Garcia’s conviction for knowing possession of stolen property; and (3) the prosecutor’s closing argument violated Garcia’s Fifth Amendment right against self-incrimination.
A. Cross-Examination of Brito
The district court has discretionary authority to rule on the admissibility of evidence, including the power to limit cross-examination.
Delaware v. Van Arsdall,
In this case, the district court limited Chaves’ cross-examination of the chief gov- *1469 eminent witness against him, Orlando Brito. Chaves sought to elicit from Brito, as evidence of a possible motive for Brito’s cooperation with the prosecution, the Florida state attorney’s nolle prosequi of a 1983 state false imprisonment charge against Brito. 9 The district court also forbade cross-examination concerning alleged wife-beating by Brito and the fact that Brito had formerly been shot. We conclude that the district court did not abuse its discretion by so limiting the cross-examination of Brito.
As previously noted, “[t]he Sixth Amendment does not require unlimited inquiry into the potential bias of a witness.”
United States v. De Parias,
B. Amendment of Model Jury Instructions
The district court deviated from the Eleventh Circuit pattern instruction to consider each defendant and each count separately,
12
stating that the jury’s decision as to the guilt or innocence of any defendant “need not necessarily” affect its verdict as to another defendant, instead of stating that the jury’s decision “should not” affect 'its verdict as to another defendant. Chaves' contends that this instruction may have encouraged the jury to impute to him his co-defendants’ knowledge that the seafood was stolen.
See United States v. Tavoularis,
*1470 We shall assume arguendo that, read in isolation, the court’s statement that the jury’s decision as to the guilt or innocence of any defendant “need not necessarily” affect its verdict as to any other defendant imputed knowledge among the defendants. Nonetheless, it is without question that the district court’s instructions, as a whole, substantially informed the jury to avoid imputing knowledge among defendants. Immediately after the above charge, the court supplemented the pattern instruction: “The important thing for you to remember[,] and particularly important in the case where you have seven defendants, is that each defendant and the case against each one, the separate counts against each one is a separate case and they should be treated individually in your consideration.” Further, the district court expressly instructed the jury that the government had to prove that each defendant knew the property was stolen. As a whole, then, the district court’s instructions amply directed the jury that its verdict as to one defendant should not affect its verdict as to any other defendant. 13 Hence, the district court’s jury charge was not an abuse of discretion. 14
C. Enhancement of Chaves’ Sentence
The district court gave two enhancements to Chaves’ sentence. First, the court found that Chaves’ offenses involved more than minimal planning and thus increased his base offense level by two steps, pursuant to United States Sentencing Guideline (“U.S.S.G.”) § 2B1.2(b)(3)(B) (Nov. 1, 1989). 15 Second, the court found that Chaves obstructed justice by attempting to induce Schlinder to hide relevant information from the FBI and thus increased his base offense level by two more levels, pursuant to U.S.S.G. § 3C1.1 (Nov. 1, 1989). 16
A finding of “more than minimal planning” is reviewed for clear error.
United States v. Scroggins,
The facts of this case confirm the district court’s determination that Chaves’ role was more than minor. His “relevant conduct” includes reasonably foreseeable actions in furtherance of the conspiracy by his coeonspirators. U.S.S.G. § lB1.3(a) (Nov. 1, 1989).
17
See also id.,
comment, (n. 1) (defining conduct for which defendant “would otherwise be accountable” to include “conduct of others in furtherance of the execution of the
*1471
jointly-undertaken criminal activity that was reasonably foreseeable by the defendant”);
United States v. Fuentes,
Chaves also attacks the two-step enhancement of his sentence based on the district court’s finding that he obstructed justice by asking Sehlinder not to speak with FBI agents. Whether the district court properly applied the obstruction of justice enhancement is a mixed question of law and fact.
United States v. Burton,
The Sentencing Guidelines mandate a two-level enhancement “[i]f the defendant willfully impeded or obstructed, or attempted to impede or obstruct, the administration of justice during the investigation or prosecution of the instant offense.” U.S.S.G. § 3C1.1 (Nov. 1, 1989). Examples of obstructive conduct include (1) directing another person to conceal material evidence and (2) threatening or unlawfully influencing a witness.
See id.,
comment, (n. 1(b)) (adjustment applicable for “directing or procuring another person to ... conceal material evidence, or attempting to do so);
id.,
comment, (n. 1(d)) (adjustment applicable for “threatening, intimidating, or otherwise unlawfully attempting to influence a ... witness, directly or indirectly”). Here, the district court enhanced Chaves’ sentence after concluding that he obstructed justice by bringing Sehlin-der into a walk-in freezer and asking him not to speak "with the FBI.
18
Provided the language used by Chaves, and the circumstances surrounding its use, the court was not clearly erroneous in finding that: Chaves’ conduct constituted obstruction of justice.
See United States v. Holland,
This Court has recognized that “[t]he sentence imposed is committed to the discretion of the trial court and, so long as the sentence falls within the range provided by statute, generally will not be reviewed on appeal.”
United States v. Funt,
D. Motion for New Trial
After sentencing, Chaves filed a motion for a new trial based upon newly discovered evidence concerning FBI agent Putnam, who served as a government witness. Chaves contends that, because Putnam was a suspect in an unrelated murder investigation by the State of Kentucky at the time of Chaves’ *1472 trial, Chaves could have impeached Putnam’s testimony and brought out bias, had the government disclosed that Putnam was under investigation. The district court denied the motion after a hearing.
A motion for new trial based on newly discovered evidence is committed to the sound discretion of the trial court and will not be overturned absent abuse of discretion.
United States v. Champion,
In this case, the district court found that Chaves failed to make out the third and fifth requirements of this test. Upon review of the record, we agree. First, Chaves fails to make out the third requirement because the newly discovered evidence at most would merely have impeached Putnam.
See Champion,
Chaves also claims that the newly discovered evidence constituted exculpatory evidence suppressed by the government in violation of
Brady v. Maryland,
E. Admission of Hearsay Testimony
Garcia maintains that the district court erred when it admitted Brito’s testimony regarding an incident in April 1989, when Garcia and Brito were driving with some others in a car. Brito testified that Guevara pointed out to him the site of a tractor trailer that the group had stolen in February 1989. The court admitted the statement against Garcia as a eoconspirator’s statement under Federal Rule of Evidence 801(d)(2)(E).
An out-of-court statement by a coconspirator is admissible under Rule 801(d)(2)(E)
20
if the trial judge determines that the government has proven by a preponderance of the evidence that (1) a conspiracy existed, (2) the defendant and the declarant participated in the conspiracy, and (3) the
*1473
statement was made during the course of and in furtherance of the conspiracy.
United States v. Turner,
However, this conclusion does not end our inquiry. The improper admission of coconspirator hearsay is subject to the harmless error rule.
United States v. Cross,
F. Sufficiency of Evidence Against Garcia
Garcia next contests the sufficiency of the evidence to support his conviction for possession of the stolen seafood under 18 U.S.C.A. § 659. Garcia claims the government failed to show that he possessed the stolen seafood. Sufficiency of the evidence is a question of law that this Court reviews
de novo. United States v. Kelly,
To sustain a conviction under section 659, the government must prove,
inter alia,
that the defendant had possession of the seafood.
See United States v. Parker,
G. Motion for Mistrial
Garcia also claims on appeal that the prosecutor intentionally referred to his failure to *1474 testify at trial, thereby violating Garcia’s Fifth Amendment right to remain silent. 24 Garcia farther contends that the district court committed reversible error when it failed to order a mistrial in response. The government contends, and we agree, that the prosecutor’s statements, rather than being a comment on Garcia’s failure to testify, were instead directed to defending the credibility of a government witness.
The standard for determining
if
a prosecutor has impermissibly commented on a defendant’s decision not to testify is “whether the statement was manifestly intended or was of such a character that a jury would naturally and necessarily take it to be a comment on the failure of the accused to testify.”
United States v. Swindall,
We review the district court’s determination of whether “manifest intent” was present under an abuse of discretion standard.
United States v. Watson,
III. CONCLUSION
Chaves’ convictions and sentence are AFFIRMED. Garcia’s convictions are also AFFIRMED.
Notes
. We consolidated the cases for the purposes of this opinion.
. On May 4, 1989, Garcia, Brito and two others drove by several cold storage facilities in the Miami metropolitan area, stopping to check the contents of tractor trailers.
Garcia, Chaves, Brito, and others participated in the theft of a tractor trailer filled with frozen seafood and the sale of its contents in mid-May, 1989.
. The bolt cutters were used to repair the refrigeration unit.
. On August 1, 1989, FBI agents Keith and Putnam and Metro-Dade Police Department detectives Alvarez and Rosario interviewed Chaves, who denied purchasing any seafood from the group and claimed not to know any of them.
. Brito became a government witness.
. The jury convicted co-defendants Diaz, Jr., and Paula of counts I, II, and IV. The jury convicted co-defendant Guevara of counts I and II. Co-defendants Diego Diaz, Sr., and Armado Perea were acquitted.
. On April 9, 1990, Chaves filed a motion for a new trial, which was denied. After filing a notice of appeal on July 12, 1990, Chaves filed a second motion for new trial, asserting grounds of newly discovered evidence. After an evidentiary hearing, the district court denied this motion.
. The Confrontation Clause provides: "In all criminal prosecutions, the accused shall enjoy the right ... to be confronted with the witnesses against him.” U.S. Const., sixth amend.
. There was no evidence that the state attorney nolle prossed this charge as part of Brito's plea bargain in this case.
. Moreover, defense counsel did cross-examine Brito about facts underlying the nolle prossed charge to the degree they bore on his credibility, such as his impersonation of a police officer in making the false imprisonment.
. Similarly, the trial court's rulings that limited the cross-examination of Brito concerning an incident in which he was injured when shot in a bar and concerning allegations that he had battered his wife were not abuses of discretion. Chaves contends that these incidents were evidence of intent under Federal Rule of Evidence 404(a) and could have impeached Brito's character under Rule 608(b). These claims are without merit.
. Eleventh Circuit Pattern' Jury Instruction (Criminal Cases) 10.4 provides in pertinent part:
A separate crime or offense is charged against one or more of the Defendants in each count of the indictment. Each offense, and the evidence pertaining to it, should be considered separately. Also, the case of each Defendant should be considered separately and individually. The fact that you may find one or more of the Defendants guilty or not guilty of any of the offenses charged should not affect your verdict as to any other offense or any other Defendant.
. Chaves further claims that the other instruction did not cure any error because the instructions were inconsistent and therefore misleading. However, "it is not sufficient simply to demonstrate that an instruction had the potential to confuse a juiy. Appellant must raise
substantial and ineradicable doubt
whether the jury has been properly guided in its deliberations.”
United States v. Pruitt,
. Furthermore, the verdicts rendered by the jury repudiate Chaves' contention that, based on the court's instructions, the jury may have imputed knowledge from one defendant to another. The jury acquitted two defendants on all counts and acquitted Chaves on counts III and IV (related to the June theft), though it convicted other co-defendants on count IV.
. We apply the version of the Guidelines in effect on the date of sentencing.
United States v. Wilson,
. As a result of the added points, the permissible range of sentencing increased from twelve through eighteen months to tweniy-four through thirty months, and the court consequently sentenced Chaves to a twenty-four month term of incarceration.
. Section lB1.3(a) defines “relevant conduct” as "all acts and omissions committed or aided and abetted by the defendant, or for which the defendant would be otherwise accountable, that occurred during the commission of the offense of conviction, in preparation for that offense, or in the course of attempting to avoid detection or responsibility for that offense, or that otherwise were in furtherance of that offense."
. Sehlinder testified that, once in the freezer, Chaves stated that the FBI had contacted him and that Sehlinder should falsely advise the FBI that he knew nothing of the April theft.
. Chaves also claims that he lacked notice that the court contemplated an enhancement based upon his conversation with Sehlinder because the presentence investigation report (“PSI”) failed to recommend an enhancement for this reason. This claim is without merit. The PSI did recommend an enhancement for obstruction of justice, and Chaves’ written objection to that recommendation specifically discussed Chaves’ conversation with Sehlinder.
. Rule 801(d)(2)(E) provides that "a statement by a coconspirator of a party during the course and in furtherance of the conspiracy" is not hearsay.
.In the superseding indictment, Garcia was charged only in counts III and V, related to the June 1989 conspiracy, not to the counts related to the April conspiracy. Thus, as presented initially by the government, Garcia was a member of the June conspiracy, not the April conspiracy for which Guevara’s coconspirator statement was made two months before Garcia's criminal involvement.
See Beale,
. Consequently, we need not address whether Federal Rule of Evidence 404(b) was violated by admitting the statement.
. Moreover, even if Garcia did not himself have direct control of the stolen property, he nonetheless had constructive possession as the cocon-spirators together exercised sufficient control over the chattel.
See United States v. De Corte,
. "No person ... shall be compelled in any criminal case to be a witness against himself." U.S. Const., amend. V.
. Further, even if the prosecutor did comment on Garcia’s failure to testify, the trial court’s curative instruction was adequate.
