OPINION
Christopher White appeals his convictions and sentence for drug trafficking. White argues,
inter alia,
that counsel for the Government committed prosecutorial misconduct by withholding material exculpatory information in violation of
Brady v. Maryland,
I.
White participated in a large-scale narcotics conspiracy that operаted in the Reservoir Hill area of Baltimore, Maryland. White was a member of the conspiracy from 1994 until his arrest in 1998, during which time he sold drugs, acted as a lookout, and performed other functions in furtherance of the conspiracy. Law enforcement officers observed White engaging in drug sales on numerous occasions. Most of these sales took place near the intersection of Lakeview and Whiteloek Streets; however, White was also observed engaging in the sale of narcotics at a nearby location on Bloom Street.
Based on evidence of these activities, White was charged with, and convicted of, conspiracy to possess with the intent to distribute and to distribute heroin, cocaine, and cocaine base, see 21 U.S.C.A. § 846 (West 1999) (Count One), and possession with the intent to distribute and distribution of cocaine, see 21 U.S.C.A. § 841(a) (West 1999) (Count Two). He now appeals, raising numerоus challenges to his convictions and sentence. We discuss below White’s claims related to the grand jury testimony of two cooperating witnesses and his challenge to his sentence under Apprendi. We have carefully reviewed the remainder of White’s claims and determined them to be without merit. 1 Accordingly, we will not discuss them further.
II.
We turn first to White’s claims concerning the grand jury testimony of Ralph Cannady and Gregory Hudson. Initially, White contends that the Government violated Brady v. Maryland by failing to provide him with transcripts of Cannady’s and Hudson’s testimony. White also maintains that the Government suborned perjury by allowing a Government witness to mischaracterize Cannady’s and Hudson’s testimony.
A.
Suppression by the Government of evidence favorable to the defense that is material to the outcome of a trial or sen
*540
tencing proceeding violates due process, irrespective of the motive of the prosecutor.
See Brady,
With these principles in mind, we turn to an examination of the grand jury testimony of Ralph Cannady, which White asserts contained materially exculpatory information. 2 In July 1998, Cannady testified that the conspiracy “sрlit” approximately five years prior to his testimony and that White established his own narcotics-dealing operation at Bloom Street. J.A. 81. Although his brief is not clear, White appears to argue that timely disclosure of this aspect of Cannady’s testimony would have allowed White to present a defense that, although he was a drug dealer, he was not part of the narcotics conspiracy alleged by the Government. 3 In light of the overwhelming evidence that White was involved in narcotics sales at Lakeview and Whitelock following the “split” alleged by Cannady, there is no reasonable probability that a defense based upon Cannady’s grand jury testimony would have been successful.
B.
Next, White asserts that the Government suborned perjury by Trooper George Cunningham of the Maryland State Police. During the sentencing hearing, Trooper Cunningham testified regarding drug quantity. His testimony was based upоn surveillance of narcotics sales during the investigation of the conspiracy; interviews with people who purchased cocaine and heroin from the conspiracy; interviews with cooperating witnesses, including Cannady and Hudson; and the grand jury testimony of Cannady and Hudson. White argues that Trooper Cunningham substantively misstated the grand jury testimony of Cannady and Hudson by asserting that those witnesses divulged that the conspirators sold heroin in “regular” and “jumbo” capsules, respectively containing one tenth of a gram and one quarter of a gram of heroin. White further asserts that the Government engаged in prosecutorial misconduct when it failed to correct these misstatements.
A conviction acquired through the knowing use of perjured testimony by the prosecution violates due process.
See Napue v. Illinois,
We conclude that no due process violation occurred here. White does not assert that Trooper Cunningham’s testimony concerning the quantity of heroin in the capsules sold by the conspiracy was inaccurate; he merely asserts that this information did not come from Cannady or Hudson. However, Trooper Cunningham’s testimoriy during the sentеncing hearing, as noted above, was based upon many sources in addition to Cannady’s and Hudson’s grand jury testimony. And, Trooper Cunningham’s testimony regarding the size of heroin capsules sold in the Baltimore area was substantially confirmed by testimony from Agent Kim Thomson with the Drug Enforcement Administration. Under these circumstаnces, there simply is no reasonable likelihood that Trooper Cunningham’s statements, even if they inaccurately summarized the grand jury testimony of Cannady and Hudson, affected the determination of drug quantity.
III.
During the pendency of this appeal, the Supreme Court held that “[ojther than the fact of a prior conviction, any fact that increases the penalty for a crime beyond the prescribed statutory maximum must be submitted to a jury, and proved beyond a reasonable doubt.”
Apprendi v. New Jersey,
Because White failed to raise this argument before the district court, our review is for plain error.
See
Fed. R.Crim.P. 52(b);
United States v. Olano,
As noted previously, White was convicted of two drug-trafficking offenses: conspiracy to possess with the intent to distribute and to distribute heroin, cocaine, and cocaine base, in violation of 21 U.S.C.A. § 846; and possession with the intent to distribute and distribution of cocaine, in violation of 21 U.S.C.A. § 841(a). 5 *542 Based on its determination that White should be held accountable for more than 30 kilograms of heroin, the district court concluded that White was subject to a guideline sentencing range of 360 months to life imprisonment. The cоurt imposed concurrent terms of 360 months imprisonment on each count of conviction. See 21 U.S.C.A. § 841(b)(1)(A) (West 1999) (providing that violation of § 841(a) involving one kilogram or more of heroin subjects a defendant to a term of imprisonment of “not ... less than 10 years or more than life”).
White argues, essentially, that becausе drug quantity was not charged as an element of the offense and found by the jury beyond a reasonable doubt, the maximum statutory term of imprisonment for each count of conviction is 20 years, or 240 months.
See 21
U.S.C.A. § 841(b)(1)(C) (West 1999). White’s position is supported by decisions from several other circuits.
6
See United States v. Baltas,
We need not decide whether White is correct. Only for рurposes of this appeal we assume, without deciding, that the sentence imposed by the district court was erroneous. We further assume, without deciding, that the error is plain. Nevertheless, we affirm White’s sentence because White has not shown that the error affected his substantial rights.
In order to establish that the error аffected his substantial rights, White must demonstrate that it was prejudicial,
i.e.,
that it “actually affected the outcome of the proceedings.”
United States v. Hastings,
In recent times, the federal sentencing process hаs been altered by the enactment of statutory minimum penalties, increases in statutory maximum penalties, and the introduction of the sentencing guidelines. To a large extent, these competing influences are reconciled by statutes and guideline provisions that recognize the
*543
preeminent role of statutory maximum and minimum penalties. For example, while a district court may depart below the sentencing range established by the guidelines, such a departure generally may not result in a sentence below the minimum term specified in the offense of conviction.
See
18 U.S.C.A. § 3553(e) (West 2000) (limiting authority of district court to depart below statutory minimum to cases in which the Government has moved for such a departure on the basis of substantial assistance);
United States v. Patterson,
In the case of multiple counts of conviction, the guidelines instruct that if the total punishment mandated by the guidelines exceeds the highest statutory maximum, the district court must impose consecutive terms of imprisonment to the extent necessary to achieve the total punishment. See U.S.S.G. § 5G1.2(d). For example, suppose a defendant is convicted of three offenses, each with a statutory maximum term of five years (60 months) imprisonment. If the district court determines that the appropriate sentence under the guidelines is 156 months, § 5G1.2(d) requires the imposition of consecutive terms on each count of conviction until the guideline punishment is achieved.
Applying these principles here, it is evident that White’s substantial rights were not affected by the imposition of a 360-month term of imprisonment on each count of conviction. Even if Whitе is correct that the maximum penalty for each of his offenses was 240 months, the district court would still have been obligated to calculate a guideline sentence by making a finding regarding the quantity of narcotics attributable to White.
7
And, in light of its determination that White’s total punishment under the guidelines should be 360 months imprisonment, the district court would have been obligated to reach that total sentence by imposing a term of imprisonment of 240 months or less on each count of conviction and ordering those terms to be served consecutively to achieve the total punishment mandated by the guidelines.
See id.; Page,
IV.
For the reasons set forth above, we affirm White’s convictions and sentence.
AFFIRMED.
Notes
. We express no view regarding the merits of White’s claims that his trial counsel was constitutionally deficient. Because the record does not conclusively demonstrate that White's trial counsel was ineffeсtive, these claims should be raised in a separate proceeding pursuant to 28 U.S.C.A. § 2255 (West Supp.2000).
See United States v. King,
. Because Hudson's grand jury testimony took place after White's trial, it cannot be said that the Government's failure to disclose it constituted suppression of evidence that may have been material to White’s guilt or innocence. And, although the
Brady
duty extends to evidence that is material to sentencing,
see Brady,
. The defense actually presentеd by White was that he was not a drug dealer at all. Cannady’s testimony was not exculpatory as to this defense.
. White also maintains that he was entitled to a jury determination of the factors that served to increase his offense level under the Sentencing Guidelines. This court has previously held, howevеr, that the constitutional rule announced in
Apprendi
does not prohibit a district court from finding, by a preponderance of the evidence, facts relevant to the application of the guidelines.
See United States v. Lewis,
. 21 U.S.C.A. § 841(b) sets forth the penalties for both offenses. See 21 U.S.C.A. § 846 (providing that "[a]ny person who ... conspires to commit any offense defined in this sub-chapter shall be subject to the same penalties as those prescribed for the offense, the com *542 mission of which was the object of the ... conspiracy”).
. This court reached a similar holding in
United States v. Angle,
. In determining the applicable guideline range, the court of course would have followed the normal procedures for determining the guideline range in a multiple-conviction case, including application of the pertinent grouping rules. See U.S.S.G. §§ 3D1.2(d), 3D 1.3(b); see also U.S.S.G. Ch.3, Pt.D, illustration 3.
