Alberto Chahia and Kelly Dean Overby were tried together and both were convicted by a jury of conspiracy to possess with intent to distribute and distribute 500 grams or more of a substance containing a detectable amount of methamphetamine. See 21 U.S.C. §§ 841(a)(1), 846. Chahia was also convicted of possession with intent to distribute a controlled substance. See 18 U.S.C. § 2; 21 U.S.C. § 841(a)(1). The district court 1 sentenced both Overby and Chahia to life imprisonment.
In this appeal, Chahia asserts that there is insufficient evidence to support the jury’s verdict; the district court abused its discretion in denying his motion for continuance; the district court erred in allowing hearsay testimony; and, his life sentence constitutes unconstitutional cruel and unusual punishment. Overby contends that he was denied a speedy trial in violation of the Sixth Amendment and that the district court erred in admitting handwritten notes he authored while in pretrial detention. We affirm.

Chahia first asserts that the evidence was insufficient to permit a reasonable jury to convict him of the offense of conspiracy to possess with intent to distribute and distribute in excess of 500 grams of a mixture or substance containing a detectable amount of methamphetamine.
We review de novo whether the evidence presented at trial was sufficient to support the verdict, viewing the evidence in the light most favorable to the verdict and giving it the benefit of all reasonable inferences. We do not weigh the evidence or assess witness credibility, and we reverse only if no reasonable jury could have found the defendant guilty beyond a reasonable doubt.
United States v. Pruneda,
The first count of the second superced-ing indictment charged Chahia, Overby, Rene Enrique Zenderas, Ruben Aaron Nieto, Jr., Timothy Charles Horn, Kellen Conlon Strutz, Rendell Rae Klein, Landon Wang, and Daniel Edward Smeltzer with conspiring to possess with intent to distribute and distribute in excess of 500 grams of a mixture or substance containing a detectable amount of methamphetamine from on or about January 1, 2006, to March 21, 2007, the date of the second superceding indictment. 2 It further alleges that the following overt acts were committed by one or more of the conspirators in furtherance of the conspiracy: the possession of such substance, with the requisite intent, within the states of North Dakota, Minnesota, California, and elsewhere; the use of telecommunications facilities; the transfer and the arranging of the transfer of methamphetamine from California and elsewhere to the Red River Valley for distribution; and, the use and threatened use of violence.
Chahia concedes that a conspiracy for the distribution of methamphetamine in the Fargo, North Dakota, area existed between Zendejas, Horn, Nieto, and others, but Chahia denies that he was a member of the conspiracy. Chahia also contends that this conspiracy ended on September 21, 2006, when Horn and Zendejas were arrested. Chahia relies upon the testimony of Horn and Zendejas. Horn testified that he received methamphetamine in North Dakota that had been shipped from California by Zendejas. Horn further testified that he did not know the identities of those persons transporting the substance. Zendejas testified that he sent Nieto from California to North Dakota with methamphetamine and that, though Chahia traveled with Nieto, Chahia only went along for the ride and had no knowledge that illegal drugs were being transported. Chahia further contends that he “began a conspiracy to sell methamphetamine with Mr. Nieto after the arrest of Tim Horn and Rene Zendejas,” which “was a wholly separate operation from Zendejas’[s] and Horn’s conspiracy.” Appellant Chahia’s Brief at 21. Our review of the record convinces us that Chahia significantly minimizes his role in the overall drug transport conspiracy.
The testimony of law enforcement officers, Overby, and Chahia’s other code-fendants described the conspiracy as beginning in the summer of 2006 when Zendejas, in California, began supplying methamphetamine to Horn and Strutz, in North Dakota. According to Zendejas’s testimony, he shipped approximately 12 pounds of methamphetamine from California to North Dakota. Horn and Strutz, in turn, distributed the methamphetamine to others, including Overby. The drug was routinely concealed inside the lining of round water coolers and transported by motor vehicle along with mustard uséd to “mask” the presence of the methamphetamine. Chahia knew that Zendej as was sending drugs to North Dakota, and Chahia himself received methamphetamine from Zendej as for distribution and personal use. Later in the summer of 2006, Chahia and Nie-to transported methamphetamine from California to North Dakota via Idaho for the sum of $2,000 each, with the substance again concealed in a water cooler.
Tim Horn’s brother, Jason Horn, initially participated in the conspiracy by allow *895 ing water coolers containing between one and one and a half pounds of methamphetamine to be stored in his apartment. In August 2006, Jason Horn began receiving one-ounce quantities of methamphetamine from Zendejas via Tim Horn. After the arrests of Tim Horn and Zendejas, Chahia continued to use water coolers to ship methamphetamine from California to Jason Horn and Strutz in North Dakota. Chahia personally delivered at least four pounds of methamphetamine to Fargo.
Finally, in November 2006, law enforcement, acting on a tip from Strutz, placed Chahia under surveillance at a casino in Mahnomen, Minnesota, where Chahia was occupying a hotel room. Chahia was observed leaving the hotel room with Nieto. Nieto was carrying two water coolers which he placed in the trunk of a vehicle. As Chahia and Nieto were entering the vehicle, they were detained by officers. Nieto was found to be in possession of 99.1 grams of methamphetamine, while Chahia had approximately 218 grams of the substance on his person. Inside the coolers, law enforcement found 57.7 grams of methamphetamine wrapped in tape and $15,500 in cash. They also found duct tape, an unopened bottle of mustard, and a third cooler in the hotel room. The methamphetamine and paraphernalia seized by law enforcement officers was introduced into evidence at Chahia’s and Overby’s trial.
“Whether a given case involves single or multiple conspiracies depends on whether there was one overall agreement to perform various functions to achieve the objectives of the conspiracy.”
United States v. Radtke,
B.
Chahia also contends that the district court abused its discretion in denying his motion for continuance. After the filing of a superceding indictment, the trial of Cha-hia, Overby, and their co-defendants was set for June 18, 2007. On June 7, 2007, Chahia filed a motion to continue, citing the government’s delivery: (1) on May 31, 2007, of a disk containing “4,569 discovery documents” 3 as well as “7.68 hours of audio material” and (2) on June 1, 2007, of “an additional 19 CD’s.” At a status conference conducted on June 11, 2007, the district court denied the motion to continue and an order to that effect was entered on June 13, 2007. On June 13, 2007, Chahia filed a second motion for continuance based upon the revelation that codefendant Zendejas was about to change his plea and testify against Chahia. On that same date, the district court denied the motion as premature, noting that the court had not been provided with any indication of the *896 content of Zendejas’s potential testimony; whether such testimony would be a surprise to Chahia; or “what remedial steps counsel seeks to take before trial commences.”
In the days prior to the trial, the United States delivered to Chahia’s counsel a transcript and audio tape of Zendejas’s statement. On the first day of trial, Cha-hia’s attorney acknowledged that he had finished reading the transcript. Finally, prior to opening statements, the district court stated that, if after the trial commenced, “the defendant believes or either of the defendants believe that they need a little extra time, you know, to take some of these issues, I’m not adverse to breaking early some day or coming in late some morning and giving you a few hours to prepare.” On the fourth day of trial, Zen-dejas testified describing the conspiracy, including Chahia’s participation in it.
Chahia contends that he was prepared for trial until the “late arrival of the new discovery.” He asserts that there was not enough time for him to review the audio recordings with his attorney or for Cha-hia’s attorney to adequately investigate the testimony disclosed in the “late” discovery, rendering him unable to rebut such testimony or impeach government witnesses. He contends that the prejudice which he suffered was particularly acute with respect to the possession with intent to distribute methamphetamine count. Specifically, Chahia alleges that additional time would have allowed him to fully appreciate the strength of the government’s case which would have motivated him to enter a guilty plea and “possibly avoid the life sentence.”
“In general, we disfavor requests for continuance and recognize that ‘[district courts are afforded broad discretion when ruling on requests for continuances.’ ”
United States v. Moe,
First, the district court did not abuse its discretion in denying Chahia’s motions for continuance. The United States provided the first set of discovery documents 13 days before trial. Chahia has not shown which of those documents, if any, were subject to pretrial disclosure or relevant to his defense. Further, Chahia has not explained how the “late” disclosure hampered his defense. As to the Zendej as transcript, Chahia’s attorney acknowledged to the district court, as the trial began, that counsel had read the transcript and he did not accept the district court’s offer of an opportunity during the trial for an extended recess in order to further review the provided materials.
Second, Chahia was not prejudiced by the district court’s denial of his motions to continue. The prejudice alleged by Chahia is that the:
Testimony and evidence admitted after the testimony of Jason Horn, especially the evidence presented against Chahia that was gathered in Minnesota at the casino where he was arrested, was strong. Mr. Chahia could have avoided this evidence if he decided to plead out after weighing that late coming discovery. But, the lateness of the discovery prevented him from obtaining a reasonable amount of time to consider that *897 evidence and negotiate to plead out instead going forth to facing both counts at trial.
Appellant Chahia’s Brief at 14. That Chahia might have elected to waive a jury trial and plead guilty if he had fully appreciated the evidence against him is speculative and, thus, insufficient to demonstrate prejudice.
See United States v. Howard, 540
F.3d 905, 906-07 (8th Cir.2008) (determining that the district court did not err in denying the defendant’s motion for continuance because “[speculation is inadequate to establish prejudice”);
United States v. Hoenig,
C.
Chahia also argues that the district court erred in allowing hearsay testimony to be introduced through Jason Horn. In accordance with
United States v. Bell,
D.
Chahia’s final claim is that his mandatory life sentence imposed under 21 U.S.C. § 841(b)(1)(A) (subjecting defendants with two prior felony drug convictions to a mandatory life sentence) constitutes cruel and unusual punishment in violation of the Eighth Amendment. However, Chahia’s constitutional claim is foreclosed by
United States v. Whiting,
II.

Overby asserts that the six and one-half months delay between his indictment on December 6, 2006 and the commencement of his trial on June 18, 2007, violated his Sixth Amendment right to a speedy trial. The Sixth Amendment provides: “In all criminal prosecutions, the accused shall enjoy the right to a speedy and public trial.... ” U.S. Const. amend. VI. This right “attaches at the time of arrest or indictment, whichever comes first, and continues until the trial commences.”
United States v. Shepard,
The Supreme Court has identified four relevant inquiries in a claim involving the Sixth Amendment right to a speedy trial: (1) whether delay before trial was uncommonly long; (2) whether the government or the criminal defendant is more to blame for the delay; (3) whether, in due course, the defendant asserted his right to a speedy trial; and (4) whether he suffered prejudice as a result of the delay.
United States v. Aldaco,
With respect to the first factor, “an accused must allege that the interval between accusation and trial has crossed the threshold dividing ordinary from ‘presumptively prejudicial’ delay.”
United States v. DeGarmo,
Significantly, this conspiracy case involved nine co-defendants. The last defendants were added by a second superceding indictment filed on March 21, 2007. In its subsequent order continuing the joint trial of these defendants, the district court noted that the second superseding indictment adding additional defendants was only recently filed; that not all of the defendants had appeared; that the charges against the defendants “arise from the same facts and circumstances”; and that “[generally, people jointly indicted together on similar evidence from the same or [a] related event should be tried together.”
See United States v. Ruiz,
Under the circumstances of this case, the six and one-half month delay between Overby’s indictment and his trial is too short a time period to be presumptively prejudicial.
See United States v. Lozano,
B.
Overby asserts that the district court’s admission into evidence of notes Overby authored violated his Sixth Amendment right to counsel. Overby wrote the notes and passed them to unindicted coconspirator, Tim Gray, while both were pretrial detainees in the Stutsman County Correctional Center in January and February 2007. In a pretrial motion, Overby asserted that the notes were inadmissible under: (1) Federal Rule of Evidence 401
6
as they were written after the alleged conspiracy had ended and thus were not relevant and (2) Federal Rule of Evidence 403
7
because, even if the notes were relevant, they were of little probative value and potentially confusing and misleading to the jury. The motion was argued and denied on the first day of trial. Gray testified at trial, and the notes were introduced through him. Overby now contends for the first time on appeal that the admission of the notes violated his Sixth Amendment right to counsel. Because this objection was not presented to the district court, we review the admission of the notes for plain error.
See United States v. Abdullahi,
In
Massiah v. United States,
However, “[a]n informant becomes a government agent for purposes of
[Massiah
] only when the informant has been instructed by the police to get information about the particular defendant.”
Moore v. United States,
To the extent there was agreement between Hartwig and the government, there is no evidence to suggest it had anything to do with Moore. The proffer agreement simply evidenced Hartwig’s willingness to disclose his knowledge of drug activity in hopes of receiving a more favorable plea agreement. Even if we were to accept Hartwig’s view that the proffer applied to his knowledge of any illegal activity, there is still no evidence that Hartwig was directed to procure additional information from Moore, or anybody else. As the District Court correctly pointed out, the fact that Hart-wig had recently signed a proffer agreement with the government seems to be an unrelated and fortuitous event. We find that the link between Hartwig’s relationship with the government and his conduct at issue here is insufficient for his actions to be attributable to the government for purposes of a Massiah violation.
Id.
at 999-1000. Similarly, here the record contains no evidence that the United States “deliberately elicited” the notes from Overby through Gray.
See Massiah,
III.
Accordingly, we affirm the judgments of the district court.
