A jury convicted Christopher Adam Walley of conspiring to distribute five grams or more of methamphetamine, and aiding and abetting the possession with the intent to distribute five grams or more of methamphetamine. On appeal, Walley challenges the jury selection process and argues that his Sixth Amendment right of confrontation was violated when the district court 1 limited his cross-examination of two prosecution witnesses. We affirm.
I.
In September 2005, Walley, Brandon Pender, and Tara Dewrock formed a conspiracy to sell methamphetamine. Pender recently had returned from Las Vegas, where he had discovered access to inexpensive methamphetamine, and Walley and Dewrock knew people to whom they could sell the methamphetamine.
According to evidence presented at trial, over the next few months, Walley and Pender took a series of trips to Las Vegas to obtain methamphetamine. On the first trip in October 2005, they were unable to obtain methamphetamine from Pender’s planned source, but did obtain a small supply for their personal use. Walley and Pender took a second trip to Las Vegas in December 2005 and brought back to Missouri about 100 grams of methamphetamine. Walley drove on the trip and provided security for the drug transaction. Walley and Dewrock then sold the methamphetamine in Missouri and provided the proceeds to Pender. In February 2006, Dewrock was caught possessing methamphetamine and marijuana. She became a confidential informant in an effort to avoid prosecution. Walley and Pender made their third and final trip to Las Vegas to obtain methamphetamine in April 2006, with Walley again driving and providing security.
When Walley and Pender returned to Missouri to meet with Dewrock, they were instead met by law enforcement officers, who had been alerted to the conspiracy by Dewrock. The officers seized 19.2 grams of methamphetamine, a cutting agent, and a set of hand scales from the vehicle, and arrested Walley and Pender. Once in custody, Walley admitted that he knew the methamphetamine was in the vehicle, that he had used some, of it twice, that he knew it was going to be distributed in southeast Missouri, and that he expected to be paid for his time driving to Las Vegas after the methamphetamine was sold.
Walley was indicted for conspiracy to distribute five grams or more of methamphetamine, in violation of 21 U.S.C. §§ 841(a)(1) and 846, and possession with intent to distribute five grams or more of methamphetamine, in violation of 21 U.S.C. § 841(a)(1). After a two-day jury trial, at which both Pender and Dewrock testified for the government, Walley was convicted of the conspiracy charge and of aiding and abetting the possession with intent to distribute five grams or more of methamphetamine. The district court sentenced Walley to 97 months’ imprisonment.
II.
Walley first argues that the district court erred in overruling his objection to
*357
the government’s peremptory strike of an African-American prospective juror. At the close of the jury selection process, Walley objected to the government’s strike of the juror, pointing out that she was the only African-American on the panel, that Walley was African-American, and that Walley was concerned about receiving a fair trial without any African-American jurors. In response to Walley’s objection, the government explained that it exercised the strike based on three factors: the prospective juror’s back problem, her dental abscess, and the fact that she knew a friend or family member with substance-abuse issues. The government elaborated that it was concerned that the prospective juror’s health issues would prevent her from being a careful and attentive juror. The district court found that the prospective juror’s back problem was not a valid basis for the government’s peremptory strike, but nevertheless determined that the juror’s abscess and connection to a person with substance-abuse issues were sufficient reasons to justify the strike. We review the district court’s denial of Walley’s objection for clear error.
United States v. Wilcox,
A party may not use peremptory strikes to exclude prospective jurors deliberately on account of their race.
See Batson v. Kentucky,
In this case, the district court did not expressly determine whether Walley made a
prima facie
showing of discrimination. When asked by the court to respond to Walley’s objection, the government stated that it had “a reason for striking [the prospective juror] that had nothing to do with her perceived ethnicity.” T. Tr. Vol. I, at 82. The district court then “cut to the chase” and requested the government’s reasoning. Though it is doubtful that Walley made a
prima facie
showing of discrimination, given that his sole argument was that the prospective juror was the only African-American on the panel,
see United States v. Roebke,
On appeal, Walley argues for the first time that the government’s failure to strike other similarly situated non-black jurors demonstrates that the government’s explanation for its strike was pretext. Our cases hold, however, that we will not consider claims of pretext based upon the failure to strike similarly situated jurors unless the point was raised in the district court.
See United States v. Hunt,
III.
Walley next contends that the district court violated his rights under the Sixth Amendment by limiting his cross-examination of prosecution witnesses Brandon Pender and Tara Dewrock. We disagree.
The Sixth Amendment provides a criminal defendant the right “to be confronted with the witnesses against him.” The primary purpose of this right is to guarantee the opportunity for effective cross-examination, particularly with respect to a witness’s potential bias.
Delaware v. Van Arsdall,
A.
Walley first argues that his right to confront Pender was violated when the district court prevented him from cross-examining Pender about the specific possible lengths of the sentence he was facing. Pender testified extensively on direct examination about the formation and operation of the drug conspiracy between Walley, Dewrock, and Pender. He also admitted that he was awaiting sentencing on the charge of conspiracy to distribute methamphetamine, was testifying pursu *359 ant to a plea agreement, and hoped to get a reduction in his sentence because of his testimony in Walley’s trial. He further explained his understanding that he would receive a reduction only if the government exercised its discretion to move for the reduction and that the judge ultimately would determine the extent of any reduction.
On cross-examination, Walley’s counsel sought to ask Pender about the forty-year maximum sentence for Pender’s offense, and the government objected. During the ensuing bench conference, Walley’s counsel also sought permission to inquire about the five-year mandatory minimum sentence. He argued that this information was relevant to Pender’s credibility, because Pender could be sentenced below this minimum sentence only if the government made a substantial-assistance motion.
See
18 U.S.C. § 3553(e). The government argued that the questioning was an impermissible attempt to present, indirectly, details about Walley’s possible sentence, because Walley and Pender were charged with the same offense.
See United States v. Thomas,
Walley relies on
United States v. Caldwell,
In this case, Walley does not argue that Pender received a reduction in the range of possible- imprisonment before he testified. Rather, Pender hoped to receive a motion by the government to reduce his sentence after the trial. There is no proffered evidence that Pender expected to receive a specific reduction, but
*360
Walley argues that he should have been permitted to elicit that Pender faced a minimum of five years’ imprisonment if the government did not move to reduce the sentence. He contends that the minimum sentence is relevant to bias, because the greater the mandatory minimum, the stronger the incentive for the witness to earn a reduction;
See United States v. Larson,
It is not self-evident that a witness facing a longer mandatory minimum has a greater desire to please the government; the witness’s motivation likely depends on the magnitude of the benefit that he expects to receive for cooperating. A fifty-year-old witness subject to mandatory life imprisonment may think a reduction to thirty-eight years is worth little, while a twenty-five-year-old facing five years would be eager to reduce the term to four.
See Larson,
We are not persuaded that evidence of Pender facing a “five-year sentence” rather than a “significant sentence” would have given the jury a “significantly .different impression” of Pender’s credibility.
Van Arsdall, 475
U.S. at 680,
*361 B.
Walley also argues that the district court erred under the Confrontation Clause by preventing him from cross-examining Dewrock about her drug trafficking activities before the formation of the charged drug conspiracy. Like Pender, Dewrock testified about the formation and operation of the drug conspiracy. She also testified about her efforts as a confidential informant that led to the arrests of Pender and Walley. She admitted on direct examination that she had been a drug user for several years, and that in return for her cooperation, the prosecuting authorities agreed to refrain from bringing charges for violations of state or federal law.
On cross-examination, Walley’s counsel elicited renewed admissions that Dewrock was involved in a conspiracy to distribute methamphetamine, and that she had distributed methamphetamine on multiple occasions. He then asked Dewrock the following question: “During the periods in which you were using significant quantities of methamphetamine over a four-year period and you were not, as you allege here, obtaining anything from Mr. Pender or Mr. Walley, you distributed other significant quantities of methamphetamine, did you not?” T. Tr. Vol. II, at 190. The government objected on the ground that the question attempted impermissibly to impeach Dewrock with prior bad acts. In response to the objection, Walley’s counsel argued at a bench conference that the question was relevant to show that Dew-rock was “minimizing her involvement” in the conspiracy. The district court sustained the objection, saying that Dewrock had admitted her role in the conspiracy and that defense counsel had “an awful lot to argue to the jury on that,” but that the proposed line of inquiry was not relevant.
Dewrock’s prior distribution of methamphetamine was not admissible for the purpose of attacking her character for truthfulness,
United States v. Turner,
Although Dewrock’s answer could have been relevant on the question of bias, Walley fails to establish that the limitation on his questioning of Dewrock constituted a plain error under the Sixth Amendment, or that there was a violation of the Confrontation Clause at all. To show such a violation, Walley must demonstrate that the excluded testimony might have given the jury a “significantly different impression” of Dewrock’s credibility.

The judgment of the district court is affirmed.
