Opinion for the court filed by Circuit Judge GARLAND.
A jury convicted, defendant George Coumaris of conspiring to help another person evade arrest by using fraudulent identification documents and Social Security numbers. Coumaris challenges his conviction, disputing several evidentiary rulings by the district court, and also challenges his sentence. We affirm Coumaris’ conviction. Upon the government’s motion, we remand the case for resentencing in light of
United States v. Booker,
— U.S. -,
I
In November 2002, a federal jury in the District of Columbia convicted Coumaris, an attorney with the Internal Revenue Service (IRS), of conspiring to commit crimes against the United States, in violation of 18 U.S.C. § 371. The objects of the conspiracy were to help Coumaris’ lover, Chris Jenkins, evade arrest for violating probation and parole obligations in the Commonwealth of Virginia, and to obtain and use fraudulent identification documents and Social Security numbers in furtherance of that end.
The government’s trial evidence showed that Jenkins and Coumaris began then-relationship in March 1998. At the time, Coumaris was aware that Jenkins was on probation and parole supervision in Virginia stemming from the latter’s 1989 convictions for burglary, grand laróeny, and robbery, and that the terms of Jenkins’ probation required him to abstain from using alcohol. Nevertheless, Jenkins continued drinking, and in December 1998 he failed a urinalysis test and was directed by his probation officer to enter a 90-day inpatient treatment program. After the 90 days, Jenkins was transferred to a residential outpatient program that allowed him to work during the day. Instead of working, Jenkins spent his days with Coumaris, who falsely represented that he was Jenkins’ employer — the fictitious “T and T Construction” company.
When Jenkins returned to the outpatient facility drunk one day, he was ordered to enter an 18-month inpatient program. Instead of enrolling in the program, Jenkins began hiding from Virginia authorities at Coumaris’ home in the District of Columbia. As a result, the Virginia Parole Board and the Fairfax County Circuit Court issued warrants for Jenkins’ arrest.
Coumaris helped Jenkins evade the authorities by providing him with false identification. Coumaris first obtained an identification card for Jenkins in the name of Brian Flowers, one of Coumaris’ former lovers. After Jenkins was arrested under Flowers’ name for driving without a license, Coumaris gave Jenkins identification belonging to another former lover, Louis Geiman, who had died a few years earlier. In addition to numerous membership cards, Coumaris helped Jenkins procure West Virginia and District of Columbia voter registration cards, a “Federal Identification System” card, and a West Virginia non-driver’s identification card, all in Geiman’s name. To obtain these cards, Coumaris and Jenkins used Flowers’ and Geiman’s Social Security numbers.
In November 1999, Jenkins ended his relationship with Coumaris and moved out of the latter’s home. ■ After Jenkins left *346 him, Coumaris falsely reported to both Fairfax County, Virginia and Washington, D.C. police that Jenkins had robbed him at gunpoint, leading to another warrant for Jenkins’ arrest. Over the next several months, Coumaris called the Fairfax County police several times with information regarding Jenkins’ whereabouts, sometimes- remaining anonymous and sometimes identifying himself as an IRS agent.
Jenkins was finally arrested in March 2000 and spent almost three months in pretrial detention on the false robbery charge. Based on information that Jenkins provided after his arrest, federal and state authorities began investigating Coumaris. In May 2000, officers executed a search warrant at Coumaris’ home, where they discovered marijuana, drug paraphernalia, and child pornography. Coumaris was subsequently interviewed by a Metropolitan Police Department (MPD) officer and an FBI agent about both the Jenkins conspiracy and the incriminating evidence discovered in his home. In an effort to hinder their investigation, Coum-aris told the FBI’s Washington Field Office that the MPD officer and FBI agent were trafficking drugs in his neighborhood.
On December 7, 2001, a federal grand jury indicted Coumaris on a single count of conspiracy, and on numerous counts of fraud in connection with identification documents and Social Security numbers. The case proceeded to trial in October 2002. At trial, Coumaris informed the court that he planned to present several character witnesses, who would testify to his honesty and truthfulness. The government filed an in limine motion seeking permission to cross-examine those witnesses about whether they had heard of several past acts by Coumaris that were assertedly inconsistent with those character traits. In response to the motion, the court first ruled that the government would be allowed to cross-examine regarding Coumar-is’ prior arrests for grand larceny and shoplifting, and a District of Columbia Court of Appeals opinion that found Coum-aris to have made false representations to a city regulatory board. Upon hearing the trial court’s ruling, Coumaris’ counsel stated: “I will listen to the other rulings, but I would suspect based upon at least your initial ruling” that “I would just withhold any character witnesses.” 10/29/02 p.m. Tr. at 15. The court then ruled that it would also allow the government to cross-examine the character witnesses about Coumar-is’ importation of marijuana from the Netherlands under a false name, and about his non-consensual recording of telephone conversations made by guests from his home. Coumaris never called the character witnesses to testify.
During the trial, Coumaris also attempted to introduce as exhibits a scrapbook and a police report. The scrapbook contained memorabilia concerning Geiman, the former lover whose identification Coumaris had given to Jenkins. The police report concerned the anonymous telephone calls that Coumaris had made about Jenkins. The court barred the introduction of both exhibits.
The jury convicted Coumaris of conspiracy but deadlocked on the remaining counts. The court declared a mistrial on the deadlocked counts and, pursuant to the United States Sentencing Guidelines, sentenced Coumaris to 48 months’ imprisonment on the conspiracy count. Coumaris appealed, challenging the court’s ruling on the in limine motion, its decisions barring introduction of the scrapbook and police report, and its calculation of the sentence.
After the parties filed their appellate briefs, the Supreme Court decided
Blakely v. Washington,
— U.S. -, -,
In Part II, we address Coumaris’ challenges to his conviction. In Part III, we discuss the disposition of his sentence in light of Booker.
II
A district court’s decision regarding the admissibility of evidence or the scope of cross-examination constitutes error only if it is an abuse of discretion.
See United States v. Whitmore,
With this understanding of the limitations on our authority, we proceed to examine the evidentiary rulings that Coum-aris maintains require reversal of his conviction.
A
Coumaris first contends that the district court erred in granting the government’s
in limine
motion to cross-examine his proposed character witnesses as to whether they had heard (1) that he had imported marijuana from the Netherlands using a false name, and (2) that he had
*348
illegally recorded telephone conversations without the consent of the participants. Coumaris concedes that, when a defendant offers witnesses to testify regarding his character, on cross-examination “inquiry is allowable into relevant specific instances of conduct,” FED. R. EVID. 405(a), “including prior convictions or arrests of the accused,”
United States v. Lewis,
Whatever its merits, Coumaris clearly waived his objection to the district court’s
in limine
ruling by failing to call the character witnesses to testify. In
Luce v. United States,
the Supreme Court held that a defendant who elects not to testify waives his right to challenge an
in limine
ruling that would have allowed the government to use a prior conviction to impeach him.
The ruling is subject to change when the case unfolds, particularly if the actual testimony differs from what was contained in the defendant’s proffer.... When the defendant does not testify, the reviewing court also has no way of knowing whether the Government would have sought to impeach with the prior conviction.... [Additionally,] a reviewing court cannot assume that the adverse ruling motivated a defendant’s decision not to testify.... Even if these difficulties could be surmounted, the reviewing court will still face the question of harmless error.... Requiring that a defendant testify in order to preserve [such] claims will enable the reviewing court to determine the impact any erroneous impeachment may have had in light of the record as a whole ....
Id.
at 41-42,
Moreover, in this case the conclusion that the defendant waived his objection is even clearer than it was in Luce. Here, the district court initially granted the government’s request to cross-examine Coumaris’ character witnesses about three other matters: Coumaris’ prior arrests for grand larceny and shoplifting, as well as a District of Columbia Court of Appeals opinion finding that Coumaris had made false representations to the District’s Alcohol Beverage Control Board. Coumaris did not object then — and does not object now — to the court’s ruling that cross-examination on those topics was permissible. See Coumaris Br. at 20 n. 6. Rather, in response to that ruling, Coumaris’ trial counsel said: “I would suspect based upon at least your initial ruling on [the prior arrests], that I would just withhold any character witnesses.” 10/29/02 p.m. Tr. at 15. *349 Counsel added that he would “talk it over with Mr. Coumaris,” but “probably the character witnesses have already been scratched based upon” the court’s initial ruling. Id.
Coumaris thus represented to the district court that he likely would not call his character witnesses irrespective of the court’s subsequent decision on the pseudonymous marijuana purchases and the non-consensually recorded conversations. In this context, any prejudice to Coumaris as a result of the court’s decision to allow cross-examination on those topics is “wholly speculative,” since we “cannot assume that the adverse ruling motivated [the] decision not to” call the witnesses.
Luce,
B
Coumaris also challenges the district court’s refusal to admit two proposed exhibits.
The first rejected exhibit was a scrapbook containing memorabilia of Coumaris’ deceased lover, Louis Geiman. The scrapbook included identification documents belonging to Geiman, as well as pictures and a funeral program. At trial, the government proved that Coumaris had given Jenkins identification documents in Geiman’s name, and that he had helped Jenkins acquire other such documents. Coumaris sought to introduce the scrapbook in order to demonstrate that he had saved Geiman’s documents for “sentimental, not illicit, reasons,” and that “Jenkins could have independently obtained the information necessary to assume Geiman’s identity.” Coumaris Br. at 22-23.
Coumaris correctly argues that the district court erred in finding the scrapbook inadmissible because it contained
hearsay. As the defendant notes, he offered the scrapbook for the nonhearsay purposes of showing why he had Geiman’s identification documents and how Jenkins might have obtained them, and not to prove the truth of the matters asserted by those documents (e.g., Geiman’s identity).
See
Fed. R. Evid. 801(c). Nonetheless, we conclude that the error was harmless, because it did not have a “substantial and injurious effect or influence in determining the jury’s verdict.”
Kotteakos v. United States,
Coumsecond evidentiary challenge is to the district court’s refusal to admit a police report “that detailed] what police officers did in relation to an anonymous call ... with respect to arresting Christopher Jenkins.” 10/29/02 a.m. Tr. at 28-29. Coumaris offered the report to *350 show that he had not harbored Jenkins, but rather had assisted the Fairfax County-police in apprehending him. At trial, Coumaris offered — and the court rejected — the report under the hearsay exception for business records set forth in Federal Rule of Evidence 803(6). On appeal, Coumaris argues that the report should have been admitted either under Rule 803(6) or under Federal Rule of Evidence 803(8)(C), which provides a hearsay exception “against the Government in criminal cases” for reports setting forth “factual findings resulting from an investigation made pursuant to authority granted by law, unless the sources of information or other circumstances indicate lack of trustworthiness.” Fed. R. Evid. 803(8)(C).
As we have noted above, a district court’s evidentiary ruling is error only if it constitutes an abuse of discretion.
See United States v. Whitmore,
In sum, we conclude that none of Coum-aris’ attacks on the district court’s eviden-tiary rulings are sufficient to justify reversal of his conviction.
Ill
Finally, Coumaris challenges several of the district court’s Sentencing Guidelines determinations. Those challenges include claims that the court improperly applied enhancements to his base offense level for abuse of a position of trust, for obstruction of justice, and for more-than-minimal planning.
See
U.S.S.G. §§ 3B1.3, 3C1.1, 2F1.1(b)(2)(A). We do not reach these challenges because we grant the government’s motion to remand the case for re-sentencing in light of
United States v. Booker,
— U.S. -,
In
Blakely v. Washington,
the Supreme Court held that Washington State’s determinate sentencing regime violated the rule of
Apprendi v. New Jersey:
“Other 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.”
Blakely,
— U.S. -, -,
The United States has moved to vacate Coumaris’ sentence and to remand for re-sentencing. The government concedes that the mandatory enhancements of Coumaris’ sentence were unconstitutional under
Booker.
It further agrees with Coumaris that, by noting in his objections to the Presentence Investigation Report that
Apprendi
had rendered the Guidelines problematic, Coumaris “made a sufficient objection in the district court to preserve a Sixth Amendment challenge to his sentence.” Gov’t Mot. to Vacate and Remand for Resentencing at 2-3. This means that the
Booker
challenge here is governed by the harmless error standard appropriate for constitutional error, which the Government states it cannot satisfy. That is, the government concedes that it cannot demonstrate “beyond a reasonable doubt that the error complained of did not contribute to the [sentence] obtained.”
Id.
at 3 (quoting
Chapman v. California,
Although Coumaris agrees that his sentence should be vacated and remanded, he urges us to resolve his specific challenges to the district court’s application of the Guidelines before remanding. Coumaris Resp. to Gov’t Mot. to Vacate and Remand for Resentencing at 2. We decline to do so. Because the district court might impose a different sentence on remand, and because the parties might choose not to appeal that sentence, consideration of objections to the court’s original guidelines calculations would be premature at best and unnecessary at worst.
IV
For the foregoing reasons, we affirm George Coumaris’ conviction. We also grant the government’s motion to vacate his sentence and to remand the case for resentencing in conformity with United States v. Booker.
So ordered.
Notes
. The question of whether the defendant's substantial rights were affected "normally requires the same kind of inquiry” under the harmless and plain error standards, "with one important difference.”
Olano,
. Because Coumaris did not raise the Rule 803(8)(C) argument in the district court, we review the court's failure to admit the report on that theory only for plain error.
