The defendant, Darin Underwood (“Underwood”), appeals his 135-month sentence for possession with intent to distribute 50 grams or more of cocaine, in violation of 21 U.S.C. § 841(a)(1) and (b)(l)(A)(iii). Underwood argues that 21 U.S.C. § 841 is unconstitutional in light of
Apprendi v. New Jersey,
After considering each of the defendant’s arguments, we affirm his conviction and 135-month sentence.
I. FACTUAL AND PROCEDURAL HISTORY
In November of 2002, the Drug Enforcement Administration (“DEA”) began investigating Underwood and his brother Darryl (“Darryl”) for drug trafficking. As part of its investigation, the DEA used a confidential informant named Victoria Hopps (“Hopps”). On November 4th, Hopps contacted Darryl by phone, and later in person, and asked to buy three ounces of cocaine base. Darryl replied that he “didn’t know nothing about all that” but that his brother, the defendant, would know everything that Hopps was asking about. Darryl directed Hopps to a location where she could find Underwood. During their face-to-face meeting, Underwood promised that he would get some cocaine to sell to Hopps.
On November 12, 2002, Underwood contacted Hopps about the cocaine, saying he had acquired some and was ready to sell. On the 15th, Darryl drove Underwood to the location of a pre-arranged meeting and dropped him off. At the meeting, Hopps purchased 51.2 grams of cocaine base from Underwood. While the transaction was occurring, law enforcement agents conducting surveillance observed Darryl parked in his car nearby. After the sale had been made, Underwood returned to Darryl’s car for a moment, and then Darryl drove off.
On November 18, 2002, Hopps was unable to reach Underwood directly, and instead contacted Darryl to arrange another meeting to purchase drugs. Later that day, Hopps met with Underwood and purchased 80.3 grams of cocaine base. After that transaction was completed, Under *1343 wood was driven away by Darryl in Darryl’s car.
On January 13, 2003, Hopps met with Underwood for the last time, inquiring once again about purchasing cocaine base. Underwood explained that there were problems with another deal in which he was involved and he would likely not be able to supply any more cocaine. Hopps later met with Darryl, who corroborated Underwood’s earlier statement that he would no longer be able to provide cocaine. In April of 2004, the DEA arrested Underwood. He was indicted on two counts of distributing, and possessing with intent to distribute 50 grams or more of cocaine, in violation of 21 U.S.C. §§ 841(a)(1) and (b)(l)(A)(iii). At trial the jury found the defendant guilty of both counts, and he was sentenced to 135 months in prison.
II. DISCUSSION
A. Booker Error.
On appeal, Underwood argues for the first time that, in light of
Booker,
the Guidelines are unconstitutional and his case should be vacated and remanded because the district court applied the Guidelines in a mandatory fashion. When a defendant fails to raise an objection in the district court on the basis of
Booker,
we review for plain error.
United States v. Rodriguez,
On appeal, Underwood maintains that he has met all four prongs under plain error review. First, he argues that the district court erred by sentencing him under the mandatory Guidelines system and that the error was plain at the time of appellate consideration. Next, he claims that because the court sentenced him to the lowest possible sentence under the Guidelines, there is an indication that, had the court sentenced Underwood through an advisory Guidelines scheme, his sentence would have been different. Finally, Underwood argues that under an advisory scheme, the court would have been able to consider the mitigating factors set forth in 18 U.S.C. § 3553, which might have resulted in him receiving a lesser sentence.
Both Underwood and the government correctly concede that the first and second prongs of the plain error test are easily satisfied. The district court erred when it sentenced Underwood because it considered the Guidelines to be mandatory, and even though the error was not plain at the time of sentencing, the subsequent issuance of
Booker
establishes that the error is plain at the time of appellate consideration.
See United States v. Shelton,
In applying the third prong of the plain error test, the burden is on Underwood to demonstrate that the plain error “affects [his] substantial rights.”
Rodriguez,
[WJhere the effect of an error on the result in the district court is uncertain or indeterminate — where we would have to speculate — -the appellant has not met his burden of showing a reasonable probability that the result would have been different but for the error; he has not met his burden of showing prejudice; he has not met his burden of showing that his substantial rights have been affected.
Id.
at 1301 (citing
Jones v. United States, 527
U.S. 373, 394-95,
The defendant’s burden has been satisfied in past cases by presenting evidence indicating that the district court was frustrated with the severity of the Guidelines and sought to find a way to have a lower sentence imposed,
United States v. Martinez,
The record indicates no frustration on the part of the district court with the severity of the Guidelines sentence, nor did the district court indicate a desire to impose a lesser sentence in Underwood’s case. As a result, Underwood’s argument relies solely on the fact the district court imposed the lowest possible sentence within the Guidelines range. We explained in
Fields,
however, that this is not sufficient to demonstrate a reasonable probability of a lesser sentence. Accordingly, Underwood has not established that his substantial rights were affected by the district court’s
Booker
error, and thus he is not entitled to relief on this issue.
See Rodriguez,
B. Constitutionality of 21 U.S.C. § 841.
Underwood argues for the first time on appeal that 21 U.S.C. § 841 is unconstitutional, in light of
Apprendi v. New Jersey,
In
United States v. Sanchez,
Under our precedent, therefore, an
Apprendi
constitutional error occurs
only
where a defendant is sentenced beyond the statutory maximum for the offense.
Sanchez,
C. The Statements from Underwood’s Brother.
At trial, the government sought to introduce and publish to the jury CD’s of recorded conversations between Underwood’s brother, Darryl, and Hopps, the confidential informant. The CD’s contained conversations clearly implicating Underwood in criminal activity. The defense objected to the introduction of the CD’s, claiming both that Darryl was not a co-conspirator in the case, and that the admission of the CD’s was barred under
Crawford v. Washington,
We review questions of constitutional law
de novo. United States v. Brown,
At trial, Underwood argued both that Darryl was not a co-conspirator and that because Hopps was working “under the auspices of law enforcement” as a confidential informant, the conversations between Hopps and Darryl were not merely “non-formal statements made by individuals to acquaintances,” but rather analogous to conversations covered by Crawford. The district judge overruled the defense objection, finding that Darryl did qualify as a co-conspirator and that Crawford did not bar admission of the evidence: “And I think clearly based on what I’ve heard so far, the brother [Darryl] was involved as a co-conspirator in this case. But Crawford seems to apply to out-of-court statements by witnesses that are testimonial, and this is not testimonial ... [i]t doesn’t seem that Crawford — the Crawford case would prohibit the introduction of these CD’s.” Underwood appeals both rulings by the district court.
We turn first to the argument that the brother was not a co-conspirator. Defendant correctly asserts that in order to introduce statements of the co-conspirator under Fed.R.Evid. 801(d)(2)(E), the government must prove by a preponder-
*1346
anee of the evidence that (1) a conspiracy existed, (2) the conspiracy included the declarant and the defendant against whom the statement is offered, and (3) the statement was made during the course of and in furtherance of the conspiracy.
Bourjaily v. United States,
Nevertheless, Underwood argues that the statements contained on the CD’s should not have been admitted at trial because they were “testimonial” statements under the meaning of the Sixth Amendment and therefore barred under the holding of
Crawford.
In
Crawford,'
the Supreme Court held that a Washington state court had committed error when it admitted at trial the tape recorded statement of the defendant’s wife, made to police, during the police interrogation of her. The interrogation concerned the involvement of the defendant and his wife in the stabbing of a man who had previously tried to rape the wife. The wife was unavailable to testify at defendant’s trial because of the spousal privilege. The Court reasoned that the statement to police had been testimonial, and that because the defendant had never had the opportunity to cross-examine his wife about the statement, admitting the statement at trial violated his constitutional rights under the Confrontation Clause.

Crawford,
Having already concluded that the challenged evidence in this case satisfies the requirements for introducing statements of a co-conspirator, Underwood’s only remaining challenge to the admission of the CD’s is whether or not the challenged evidence was “testimonial.” The Court noted that the Confrontation Clause applies to “witnesses” who bear testimony, which the Court indicated is typically a solemn declaration or affirmation made for the purpose of establishing or proving some fact.
Id.
at 51,
In this case, the challenged evidence consisted of recorded conversations between the confidential informant and Darryl in which arrangements were made for the confidential informant to purchase cocaine. This evidence is neither testimony at a preliminary hearing, nor testimony before a grand jury, nor testimony at a former trial, nor a statement made during a police interrogation. Moreover, the challenged evidence does not fall within any of the formulations which
Crawford
suggested as potential candidates for “testimonial” status.
Crawford,
Although the foregoing discussion would probably support a holding that the evidence challenged here is not “testimonial,” two additional aspects of the
Crawford
opinion seal our conclusion that Darryl's statements to the government informant were not “testimonial” evidence. First, the Court stated: “[m]ost of the hearsay exceptions covered statements that by their nature were not testimonial — for example, business records or statements in furtherance of a conspiracy.”
Id.
at 55,
For the foregoing reasons, we conclude that the challenged evidence in this case was not “testimonial,” 2 and that it satisfied *1348 the requirements for the admission into evidence of co-conspirator statements. Accordingly, the district court did not err in admitting the evidence.
III. CONCLUSION
After consideration of each of the defendant’s arguments, we conclude that the judgment of the district court is
AFFIRMED.
