Nicholas Padilla appeals his jury conviction of being a felon in possession of a firearm, in violation of 18 U.S.C. § 922(g)(1). Padilla argues that his motion for new trial should have been granted because, after his conviction, a state court invalidated his predicate state conviction
nunc pro tunc.
Padilla also challenges the district court’s admission of a statement obtained from him allegedly in violation of
Miranda v. Arizona,
After this appeal had been submitted for decision, the Supreme Court of the United States decided
Blakely v. Washington,
— U.S.-,
I. Background
In July 2Ó02, Nicholas Padilla was convicted of being a felon in possession of a firearm, in violation of 18 U.S.C. § 922(g)(1). Padilla’s prior felony was a California state conviction in January 1997 for possession of cocaine for sale. The felon-in-possession charge stemmed from Padilla’s conduct on January 30, 2001, when two Los Angeles police officers made a traffic slop of Padilla’s vehicle. Padilla stepped out of his vehicle, withdrew a loaded .38 caliber revolver from his waistband and threw it away before he and his passenger, Gustavo Villa, fled on foot. Prior to trial, Padilla stipulated that he previously had been convicted of a felony punishable for á term exceeding one year. The only disputed issue at trial was whether Padilla was in possession of the gun on January 30, 2001.
The government called three witnesses in its case in chief. Los Angeles Police Officers Parga and Kirkpatrick testified as to the events of January 30, 2001. Parga was the only-one to see Padilla dispose of the gun. Federal Bureau of Investigation (“FBI”) Special Agent Scott Garrióla testified with regard .to two contradictory *1090 statements that Padilla made to him; the first of those statements is challenged by Padilla in this appeal.
Two witnesses testified for the defense. The passenger in the car, Villa, testified that the gun was his and that Padilla did not know that Villa had the gun when he got into Padilla’s car. Villa also testified that both he and Padilla were members of the Cuatro Flats street gang. The second defense witness was Samantha Ramirez, who corroborated some of Villa’s testimony.
In rebuttal, the government called Detective William Eagleson as an expert on gangs. Eagleson testified that it was his experience that gang members would not testify against one another, and that violation of this basic gang tenet would lead to violent retaliation. Eagleson further testified that, in his experience, gang members at a lower level within the gang hierarchy would often take the blame for a higher status member in order to demonstrate their loyalty to the gang. Finally, he testified that if a lower ranking member failed to take the blame for a higher ranking gang member, he would likely suffer severe retaliation, perhaps even death.
The jury returned a guilty verdict. Approximately six months after Padilla’s conviction, the Los Angeles Superior Court entered an order vacating Padilla’s state felony conviction “nunc pro tunc to January 9, 1997,” because Padilla had been a minor at the time that he was convicted as an adult. Padilla moved for a new trial on the strength of the state court’s order. The district court denied the motion.
II. Discussion
A
Padilla contends that the district court was required to grant his motion for a new trial because the state court’s order vacating his predicate conviction
nunc pro tunc
rendered his federal conviction for violating 18 U.S.C. § 922(g)(1) invalid. The district court rejected this argument, ruling that the state court’s order did not affect Padilla’s status as a felon at the time he possessed the firearm. We review for an abuse of discretion a district court’s denial of a motion for a new trial.
See United States v. Reyes-Alvarado,
The Supreme Court has held that a pri- or conviction that is subject to collateral attack on the ground of constitutional invalidity may nevertheless serve as the predicate felony conviction for a charge of being a felon in possession of a firearm.
See Lewis v. United States,
An examination of § 1202(a)(1) reveals that its proscription is directed unambiguously at any person who “has been convicted by a court of the United States or of a State ... of a felony.” No modifier is present, and nothing suggests any restriction on the scope of the term “convicted.” “Nothing on the face of the statute suggests a congressional intent to limit its coverage to persons [whose convictions are not subject to collateral attack.]” The statutory language is sweeping, and its plain meaning is that the fact of a felony conviction *1091 imposes a firearm disability until the conviction is vacated or the felon is relieved of his disability by some affirmative action, such as a qualifying pardon or a consent from the Secretary of the Treasury.

teaches that “a convicted felon [must] challenge the validity of a' prior conviction, or otherwise remove his [firearm] disability,
before
obtaining a firearm.”

Padilla contends' that Lewis and its progeny do not apply to his' case because his state conviction suffered from a more fundamental defect than the convictions in those cases did. His conviction,' he asserts, was void ab initio because the adult division of the court had no jurisdiction over Padilla, a juvenile, in the absence of a transfer hearing and order. We reject this argument for several reasons. First, we are not convinced that the flaw in Padilla’s state conviction was any more fundamental than that in Lewis, which involved a conviction attended by a denial of the right, to counsel. Second, as Padilla concedes, the. state court did not lack subject matter jurisdiction over his- case; the only “jurisdictional” question concerned which; division of the state court should exercise the subject matter jurisdiction that the court unquestionably had over his case. Third, the policy and congressional purpose of § 922(g) are served by requiring a felon to clear his felony record before possessing a firearm no matter what infirmity infects his conviction.
Padilla relies primarily on the reasoning of
United States v. Mayfield,
Padilla argues that a 1986 amendment to the federal firearms statute requires a different result from that reached in the Lewis line of cases, including the Tenth Circuit’s decision in Mayfield. In 1986, Congress amended the statute to provide that the term “crime punishable by imprisonment for a term exceeding one year” is defined as follows:
What constitutes a conviction of such a crime shall be determined in accordance with the law of the jurisdiction in which the proceedings were held. Any conviction which has been expunged, or set aside or for which a person has been pardoned or has had civil rights restored shall not be considered a conviction for purposes of this chapter, unless such pardon, expungement, or restoration of civil rights expressly provides that the person may not ship, transport, possess, or receive firearms.
18 U.S.C. § 921(a)(20). Padilla contends that this language has the effect of overruling the holding in Lewis and making state law controlling as to both the retroactive effect of a subsequent state order vacating a predicate felony conviction and the question whether the conviction was void ab initio.
Padilla’s argument cannot be squared with the plain language of the amended § 921(a)(20), which refers to a conviction that
“has been
expunged, ... or for which a person
has been
pardoned or
has had
civil rights restored.” (emphasis added). This phraseology suggests no change in the rule of
Lewis
or
Mayfield;
the ex-pungement, pardon, or restoration of civil rights (whether or not on the ground that the conviction was void
ob initio)
must occur before the erstwhile felon takes possession of a firearm. The controlling state determination operates only
prospectively,
so that
after
the expungement, pardon, or restoration of civil rights that felony conviction no longer serves to impose a firearm disability. The amendment does not mean, however, “that such a conviction was not disabling between the time it was obtained and the time it was set aside.”
United States v. Kahoe,
Our recent decision in
United States v. Marks,
The district court accordingly did not abuse its discretion in denying Padilla’s motion for new trial, founded as it was on the state court’s nunc pro tunc order. 2
B
Padilla next contends that the district court erred in admitting a statement that
*1093
he made to FBI Special Agent Scott Garri-óla, a member of the FBI’s Fugitive Task Force. The statement was made while Padilla was in custody without having been given the warnings required by
Miranda,
Agent Garrióla had previously met with Padilla in connection with Garriola’s investigation into the whereabouts of a fugitive named Joe Luis Saenz, but Padilla refused to assist in the investigation. The statement in issue was made when Agent Garrióla went to the state prison facility and placed Padilla under arrest pursuant to the federal warrant for felon-in-possession charges. Agent Garrióla advised Padilla of the federal charges and told him that he was being taken to make his initial appearance before a magistrate judge, but he did not give Padilla any Miranda warnings. Agent Garrióla said something to the effect that this was Padilla’s last chance to cooperate in the Saenz investigation. Padilla responded by declaring that he was not worried about the federal firearms case because the police had planted the gun. The district court concluded that this statement was not the product of interrogation and permitted the government to admit it into evidence. 3
We conclude that the statement was the result of interrogation.
4
Interrogation is defined as express questioning and its functional equivalent.
See Rhode Island v. Innis,
Agent Garriola’s “last chance to cooperate” statement constituted interrogation because the agent should have known that it was reasonably likely that such a comment would evoke an incriminating response. It is difficult to imagine any purpose for such a statement other than to elicit a response. The fact that Agent Garrióla was seeking a response with regard to a separate investigation does not alter our conclusion. The “last chance” of which Padilla had been advised was the last chance for a possible bargain over Padilla’s federal charges, and a response related to those charges was a natural result of the question. The question was “reasonably likely to evoke an incriminating response.”

The error, however, was harmless beyond a reasonable doubt.
See United States v. Butler,
C
Finally, Padilla challenges the admission of gang expert testimony.
5
The district court permitted the gang expert testimony for the limited purpose of impeaching the exculpatory testimony offered by Villa, the car passenger. The government offered the gang expert’s testimony only after Villa testified that both he and Padilla were gang members and that the gun was his rather than Padilla’s. Padilla argues that the district court failed to discharge its gatekeeping duties under
Daubert v. Merrell Dow Pharm., Inc.,
We have addressed the issue of gang experts in similar contexts in
United States v. Hankey,
Similarly, here, the district court considered Detective Eagleson’s extensive experience with Los Angeles street gangs, and the Cuatro Flats gang in particular, and determined that he was reliable within the meaning of Federal Rule of Evidence 702. The record supports that determination; there was no abuse of discretion.
The district court also weighed the countervailing factors of Rule 403, and determined that the probative value of the expert’s testimony with regard to bias and the ultimate credibility of Villa as a witness was not substantially outweighed by any unfair prejudice that might result. That ruling was also not an abuse of discretion. The subject of gang membership had been thoroughly aired before the gang expert testified. His testimony concerning gang punishment for junior members who fail to support senior members was probative on the truthfulness of Villa’s testimony. Although the expert testimony was detrimental to Padilla’s case, it was within the district court’s discretion to conclude that it was not unfairly prejudicial within the meaning of Rule 403.

As we stated at the outset of this opinion, we have determined in the interest of judicial economy to remand this case to the district court so that it may address in the first instance the sentencing issues raised by
Blakely,

III. Conclusion
The conviction of Padilla is affirmed. The case is remanded to the district court for further proceedings, as necessary, with regard to Padilla’s sentence.
CONVICTION AFFIRMED; SENTENCE REMANDED.
Notes
. The Court in
Lewis
noted that there was no significant difference between the statutory provision at issue there and 18 U.S.C. § 922(g)(1), because "[e]ach seeks to keep a firearm away from 'any person ... who has been convicted' of a felony.”
