A jury found Gary O’Dell guilty of one count of conspiracy to commit money laundering, in violation of 18 U.S.C. § 1956(h), five counts of money laundering, in violation of 18 U.S.C. § 1956, and one count of conspiracy to distribute controlled substances, in violation of 21 U.S.C. § 846. The district court, 2 on May 26, 1999, sentenced O’Dell to 210 months on the drug count and 78 months on the money laundering counts, the sentences to run concurrently. O’Dell appeals his conviction and sentence. We affirm.
I.
O’Dell’s conviction stems from his participation in a drug trafficking scheme based out of Mason City, Iowa. Steve Gomez headed the drug trafficking organization; O’Dell, along with several others, worked for Gomez.
The Gomez organization dealt in large amounts of methamphetamine, marijuana, and cocaine. The group obtained the drugs from sources Gomez had developed and maintained in Arizona and California. The evidence showed that Gomez or one of his associates would travel to one of these states, purchase the drugs, and then return to Iowa where the drugs would be sold. The money used to purchase the drugs came from the proceeds of past drug sales.
*833 O’Dell started working for Gomez in 1995 and was allegedly a member of the Gomez conspiracy until 1997. Government witnesses testified that O’Dell stored methamphetamine and marijuana in his house for Gomez. In addition, several of these witnesses testified that O’Dell made trips, four in total, to Arizona and California to purchase drugs and bring them back to Iowa. One witness testified that, on one of these trips, O’Dell helped in an attempt to manufacture methamphetamine out of ephedrine. The evidence also showed that O’Dell helped “rerock” or “ct” methamphetamine, and that he counted drug money for Gomez.
In addition, the government identified several occasions on which O’Dell used Western Union to wire money to Arizona to purchase drugs, or obtained a cashier’s check and sent that through the mail for the same purpose. In doing so, O’Dell often used a fictitious name to help conceal the reason for sending the money. O’Dell also received a cashier’s check in the amount of $10,000, sent to him at Gomez’s direction, while he was in Arizona. The money came from drug proceeds and was used to purchase more drugs.
O’Dell was charged, along with Gomez and several others, with conspiracy to commit money laundering, money laundering, and conspiracy to distribute drugs. By the time O’Dell went to trial, most of his codefendants had pled guilty, and some of them testified against him at his trial. O’Dell’s trial lasted four days, and the jury returned a verdict of guilty on the two conspiracy counts and on five of the substantive money laundering counts.
On appeal, O’Dell alleges the district court made two errors at trial and three at sentencing. For the trial issues, O’Dell argues that the district court erred in admitting evidence that O’Dell possessed methamphetamine and in refusing to grant a mistrial after the prosecutor made improper remarks in his rebuttal closing argument. For the sentencing issues, O’Dell contends that the district court erred in enhancing his sentence for obstruction of justice, in failing to reduce his sentence for playing a minor or minimal role in the conspiracy, and in failing to reduce his sentence under the so-called “safety valve” provision. We consider each of these arguments in turn.
II.
A. Admission of Evidence
O’Dell argues that the district court erred in admitting evidence that he possessed methamphetamine. We review a district court’s decision to admit evidence for an abuse of discretion.
United States v. McMurray,
34 F,3d 1405, 1411 (8th Cir.1994),
cert. denied,
Our cases have firmly established that crimes or acts which are “inextricably intertwined” with the charged crime are not extrinsic and Rule 404(b) does not apply.
See United States v. Severe,
Moreover, the probative value of the evidence is not substantially outweighed by its prejudicial effect.
See United States v. Bass,
B. Prosecutorial Misconduct
O’Dell next argues that the district court erred in refusing to grant a mistrial after the prosecutor made inaccurate and misleading statements during his rebuttal closing argument. Prosecutorial misconduct is grounds for a mistrial where (1) the prosecutor’s remarks are in fact improper, and (2) the remarks prejudicially affect the defendant’s substantial rights so as to deprive the defendant of a fair trial.
United States v. Hernandez,
In his rebuttal closing argument, the prosecutor addressed the government’s ability to compel witnesses to testify:
[T]his Government cannot force somebody to testify if they don’t want to. Even if they’re convicted of a crime, there is no way for the Government to force the person to take the stand to tell what they know. You can’t draw out the facts from them of [sic] their knowledge in any way by forcing them to do it. You can’t threaten them. You can’t put them in jail longer. There’s no way to draw out the facts they know from them. The only way we can do it in this system is to do it voluntarily.
(Prosecutor’s Closing Argument Tr., at 38-39.) We agree with O’Dell, and the government does not seriously contend otherwise, that these remarks were in fact improper. “The power of government to compel persons to testify in court or before grand juries and other governmental agencies is firmly established in Anglo-American jurisprudence.”
Kastigar v. United States,
Yet, even where the Fifth Amendment is implicated, the government may compel a witness to testify if the government grants the witness immunity from future prosecution.
See id.
at 453,
This does not end our inquiry, however. The remarks, when reviewed in the context of the whole trial, must have been “so offensive as to deprive the defendant of a fair trial.”
Hernandez,
We start with the third factor. Right after the prosecutor finished his rebuttal, the district court expressed its concern outside of the presence of the jury that the remarks were “very misleading.” After a discussion with counsel for both parties, the district court decided it was best to issue the following curative instruction to the jury immediately:
[The prosecutor] told you that the Government cannot force somebody to testify if they don’t want to, even if they’re convicted of a crime, and that they can’t go to jail for any longer if they refuse to testify. And that’s not an accurate statement of the law. The Government may give witnesses use immunity, and you saw an example of it in this very case, and there are other methods available to the Government to obtain the testimony of a witness in this case. And I just want you to remember that you’re the sole judges of the credibility of witnesses, and the weight to be given any witness’ testimony is solely in your discretion.
(Jury Instr. Re Closing Argument Tr., at 65-66) (emphasis added).
O’Dell argued to the district court and contends on this appeal that this instruction did not go far enough to remedy the error. He offered his own instruction which detailed additional ways for the government to compel testimony and suggests that the district court erred in refusing to give his version. Our long-standing rule, however, is that a defendant “ ‘is not entitled to a particularly worded instruction where the instructions given, when viewed as a whole, correctly state the applicable law and adequately and fairly cover the substance of the requested instruction.’ ”
United States v. Gundersen,
Furthermore, the remaining two factors do not support a finding that the remarks were so prejudicial that O’Dell was deprived of a fair trial. The remarks were an isolated event, occurring during rebuttal closing arguments, and there is nothing to suggest that there was a cumulative detrimental effect. The properly admitted evidence, moreover, was certainly strong enough to support the verdict.
*836
While we conclude that the remarks were improper, they were not prejudicial to the degree of depriving O’Dell of a fair trial. We find that the district court did not abuse its discretion in refusing to grant a mistrial.
See United States v. Emmert,
III.
A. Enhancement for Obstructing or Impeding the Administration of Justice
O’Dell maintains the district court committed three errors in sentencing. His first argument is that the district court erred in increasing his offense level by two levels for obstructing justice at a pretrial release revocation hearing. We review a district court’s factual findings in support of an obstruction of justice enhancement for clear error and its application of the sentencing guidelines to the facts
de novo. United States v. Molina,
The sentencing guidelines provide for a two level enhancement in a defendant’s offense level “[i]f the defendant willfully obstructed or impeded, or attempted to obstruct or impede, the administration of justice during the investigation, prosecution, or sentencing of the instant offense.”
U.S. Sentencing Guidelines Manual
§ 3C1.1 (1995).
4
A defendant who commits perjury is subject to this enhancement,
United States v. Berndt,
The district court found that O’Dell committed perjury when he testified before a magistrate in a bond revocation hearing on May 11, 1998. The magistrate held the hearing after O’Dell was apprehended and later charged with a drug crime while he was out on pretrial release in the present *837 case. Police had stopped O’Dell on March 16, 1998, for a traffic violation when they discovered a substance hidden in his jacket that field-tested positive for methamphetamine. The substance turned out to be a caffeine mixture, and O’Dell was charged with possession with intent to distribute a simulated controlled substance under Iowa law. At the hearing before the magistrate, O’Dell testified that he had mistakenly put on a jacket that belonged to someone else, and that he did not know that the simulated drugs were in the jacket. The magistrate found this testimony to be “entirely lacking in credibility.” At sentencing, the district court made its own independent findings and concluded that O’Dell had committed perjury. We cannot conclude that the district court clearly erred in doing so.
Nor are we impressed with O’Dell’s other argument: that the perjury must be material to the underlying offense. The word “material” is defined in the commentary to section 8C1.1 to mean “evidence, fact, statement, or information that, if believed, would tend to influence or affect
the issue under determination.” U.S. Sentencing Guidelines Manual
§ 3C1.1 commentary 5 (emphasis added). Consistent with this definition, our cases have repeatedly upheld an enhancement under section 3C1.1 where the perjurious testimony did not go to the underlying charge, but the issue being decided.
See United States v. Lank,
Here, the “issue under determination” was whether O’Dell’s pretrial release should be revoked. O’Dell’s perjurious testimony had the potential to influence or affect that determination. Enhancing O’Dell’s offense level was therefore proper.
B. Reduction for Mitigating Role
O’Dell’s second argument regarding his sentence is that the district court erred in refusing to decrease his offense level based on his role in the Gomez organization. Section 3B1.2 of the sentencing guidelines provides for a reduction in a defendant’s offense level if the defendant was either a “minimal” or “minor” participant in the criminal activity. The former is entitled to a four level reduction; the latter is entitled to a two level reduction.
U.S. Sentencing Guidelines
§ 3B1.2. As the defendant, O’Dell had the burden of proof on this issue.
United States v. Wilson,
O’Dell’s claim that he is entitled to a role reduction is not persuasive. Only those defendants who are among the “least culpable of those involved” are considered “minimal” participants, and only those who are “less culpable than most other participants” are considered “minor” participants.
U.S. Sentencing Guidelines
§ 3B1.2 commentary 1, 3. Here, although O’Dell may have been less culpable than Gomez, he nevertheless was “deeply in
*838
volved” in the illegal conduct of the Gomez organization.
See Wilson,
C. Reduction under the “Safety Valve” Provision
O’Dell’s final contention is that the district court erred in refusing to reduce his sentence under the so-called “safety value” provision of
U.S. Sentencing Guidelines
§ 5C1.2.
See also
18 U.S.C. § 3553(f). The “safety valve” provision permits a district court to impose on a drug defendant a more lenient sentence within the otherwise applicable guidelines range if certain conditions are met.
United States v. Romo,
Section 5C1.2 lists five requirements which must be satisfied before a defendant may qualify for a reduction. Among them, and the only one at issue here, is the requirement that the defendant
truthfully provide[] to the Government all information and evidence the defendant has concerning the offense or offenses that were part of the same course of conduct or of a common scheme or plan ....
U.S. Sentencing Guidelines § 5C1.2(5). At his sentencing hearing, special agent John Graham testified for the government that, even after his conviction, O’Dell continued to deny his involvement in the essential conduct of which the jury found him guilty. For example, special agent Graham testified that O’Dell, in his presen-tence interview, maintained that he had no knowledge of transporting drugs' from Arizona to Iowa. O’Dell also stated in the interview that he felt the wire transfers were for cars, not drugs, and he denied that he ever stored any drugs at his house. The district court, based on this testimony and its own credibility assessments, concluded that O’Dell had not been “completely truthful” in his debriefing, and therefore denied a reduction under the “safety valve” provision. We cannot say that this finding is clearly erroneous.
IV.
For the foregoing reasons, we affirm the judgment of the district court.
Notes
. The HONORABLE MARK W. BENNETT, United States District Judge for the Northern District of Iowa.
. Fed.R.Evid. 404(b) provides in relevant part, “Evidence of other crimes, wrongs, or acts is not admissible to prove the character of a person in order to show action in conformity therewith.”
. We note that O'Dell has quoted to this Court the version of section 3C1.1 found in the 1998 edition of the
U.S. Sentencing Guidelines Manual.
We assume, however, that the district court applied the 1995 edition because, according to the presentence report (PSR), the guidelines have changed to the disadvantage of the defendant since the present offense was committed. (PSR ¶ 86.) Therefore, the guidelines in effect at the time of the offense of conviction, that is, the 1995 edition, applied.
Id.
(citing
U.S. Sentencing Guidelines Manual
§ 1B1.1 l(b)(l)-(2)). Regardless, our analysis of the issue in this case under both the 1995 and 1998 editions is the same, even though the 1998 edition contains an amended version of section 3C1.1. This is.because the amendment addresses a situation unrelated to O’Dell’s enhancement for obstruction of justice. In particular, section 3C1.1 was amended to make it clear that it applies to those situations in which the obstruction occurs in a case closely related to the defendant’s case, such as that of a codefendant.
