Gabriel Andaverde appeals from his criminal conviction for being a felon in possession of a firearm in violation of 18 U.S.C. § 922(g)(1) and for possessing a stolen firearm in violation of 18 U.S.C. § 922(j). He contends that 18 U.S.C. § 922(g)(1) violates the Fifth and Tenth Amendments, that several of his post-arrest statements were inadmissible, and that an insufficient interstate commerce nexus was shown at trial under 18 U.S.C. § 922(j). We affirm the district court on all issues relating to his conviction under 18 U.S.C. § 922(g), but, in light of this court’s recent decision in
United States v. Cruz,
I.
On January 31, 1991, Andaverde was convicted in state court of first degree burglary and was subsequently imprisoned. At the time of the events at issue here, he had been released and was on probation. Corrections Officer Spurgeon Keeth supervised Andav-erde as part of his probation. Andaverde lived at his mother and step-father’s home, where he had his own bedroom.
*1308 On October 27,1993, police officers executing a search warrant 1 searched the family home, finding a shotgun underneath Andav-erde’s bed in his bedroom. This shotgun had been taken from a neighbor’s truck a few days before. After finding the gun, the police took Andaverde to the police station, where he was given a Miranda warning by Detective Julius Schenck. After advising Andaverde of each of his rights, Schenck asked him if he understood the right. An-daverde separately indicated that he understood each right, and he signed a written waiver form. Schenck questioned him for at most two hours and then walked Andaverde out to where Corrections Officer Keeth was waiting, directly outside of Schenck’s office. Schenck told Keeth that Andaverde had been Mirandized, had made a statement, and that Keeth could now talk to Andaverde. 2
Without reinforming Andaverde of his rights, Keeth began questioning him about a possible probation violation for possessing a gun. Andaverde told Keeth that his brother had stolen the gun and brought it into the house, but that he did not know how it got underneath his bed.
Schenck testified that when Andaverde and Keeth began talking, he remained on the scene and listened to the questioning. 3 He heard Andaverde make the statement about his brother and the gun.
The next day, October 28, Keeth again questioned Andaverde at the jail, again without issuing a Miranda warning. During that interview, Andaverde initially denied knowing how the shotgun got under the bed. However, after Keeth expressed his disbelief, Andaverde admitted that he himself had put the gun under his bed.
On October 29, 1993, Andaverde indicated that he wanted to speak to Bureau of Alcohol, Tobacco, and Firearms (“ATF”) Agent Robert Wyatt, who was meeting with Andav-erde to fingerprint him. Before taking the statement, Wyatt advised Andaverde of his rights. Andaverde refused to sign a waiver form. However, he acknowledged that he understood his rights, and he subsequently made statements to Wyatt. The record is unclear as to whether those statements were made in response to questions by Wyatt, or were spontaneously offered by Andaverde. During this interview, Andaverde stated that he knew that the shotgun was under his bed. Subsequently, Andaverde refused to answer further questions.
At trial, the district court judge refused to dismiss the criminal indictment. Andaverde was subsequently convicted in federal court under 18 U.S.C. § 922(g)(1) as a convicted felon in possession of a firearm, and under 18 U.S.C. § 922(j) for storing or concealing a stolen firearm.
II.
The first count of the indictment was brought pursuant to 18 U.S.C. § 922(g)(1), which prohibits convicted felons from possessing firearms. Andaverde contends that he was not a convicted felon subject to prosecution under that statute, and, additionally, that his prosecution violates the Fifth and Tenth Amendments. We apply
de novo
review to a denial of a motion to dismiss a
*1309
criminal indictment on constitutional grounds.
United States v. McDougherty,
Under 18 U.S.C. § 922(g)(1), convicted felons are prohibited from possessing firearms. The statute provides that:
It shall be unlawful for any person ... who has been convicted in any court of [] a crime punishable by imprisonment for a term exceeding one year ... to receive any firearm or ammunition which has been shipped or transported in interstate or foreign commerce.
18 U.S.C. § 922(g)(1).
Courts determine what constitutes a conviction for the purposes of § 922(g)(1) by looking to the law of the jurisdiction where the proceeding was held. 18 U.S.C. § 921(a)(20). Section 921(a)(20) provides that:
Any conviction which has been expunged, or set aside or for which a person has civil rights restored shall not be considered a conviction for purposes of this chapter, unless such a pardon, expungement, or restoration of civil rights expressly provides that the person may not ship, transport, possess, or receive firearms.
(emphasis added). Under this provision, enforcement of § 922(g)(1) depends upon the felon’s status under state law. Consequently, a federal court must look to state law in order to determine whether a convicted felon falls into the category of persons prohibited from possessing firearms.
Andaverde first argues that, because Washington state law did not prohibit him from possessing a shotgun, 4 he should be considered as having had his civil rights restored. Therefore, Andaverde contends, his conviction is not a conviction for § 922(g)(l)’s purposes.
Andaverde is incorrect. In determining whether a felon continues to suffer a civil rights disability, the Ninth Circuit considers whether the felon has been restored the right to vote, sit on a jury, and hold public office.
United States v. Meeks,
Under Washington state law, a felon’s civil rights are restored in full when he completes the requirements of his sentence and is thereby discharged. Wash.Rev.Code § 9.94A.220. However, until a felon is discharged, state law prevents him from serving on a jury, holding public office, and voting. Wash.Rev.Code §§ 2.36.070(5) (Supp.1995), 29.65.010(3); Wash. Const. Art. 6, § 3. There is no evidence in the record that An-daverde has been discharged. Andaverde thus substantially lacked civil rights when he was prosecuted under § 922(g)(1).
Cf. Dahms,
A.
Andaverde further contends that his conviction under § 922(g)(1) violates the equal protection assurances contained in the Due Process Clause of the Fifth Amendment because § 922(g)(1) differentiates between convicted felons who are on probation and those who are not.
This argument is unpersuasive. Congress could rationally conclude that convicted felons who have successfully completed their probation, and, presumptively, have been reintegrated into society may better be trusted with the right to possess firearms than convicted felons who have yet to prove themselves rehabilitated. Andaverde’s equal protection claim must fail.
B.
Andaverde argues that his prosecution impermissibly interferes with state laws allowing felons to bear firearms, because that area of regulation was left to the states under § 922(g)(1). We disagree. Section 922(g)(1) rests on state law governing convictions, not on state law regulating felons’ possession of firearms. The section requires the courts to look at the state’s definition of convictions, not at the state’s substantive regulation of convicted felons. Congress may regulate possession of firearms without violating the Tenth Amendment.
United States v. Tomlin,
III.
Andaverde argues that his post-arrest statements to Corrections Officer Keeth were involuntary because Keeth never informed him of his rights. The voluntariness of a confession is determined by the totality of the circumstances, which we review
de novo. Northern Mariana Islands v. Mendiola
A.
Andaverde contends that his statement to Keeth on the day of his arrest, October 27, was inadmissible because Keeth failed to inform him of his rights, even though the police had Mirandized him at most two hours previously, and there was at most a ten minute interval between his questioning by police and his questioning by Keeth.
Statements made to a probation officer by a person in custody are subject to a voluntariness determination.
Jones v. Cardwell,
We have previously ruled that an inadequate
Miranda
warning given by a parole officer renders the defendant’s subsequent confession inadmissible.
United States v. Bland,
We note that the Fifth Circuit has held that probation officers must
Mirandize
defendants in custody.
United States v. Deaton,
A probationer cannot pretend ignorance of the fact that his probation officer “is a peace officer, and as such is allied, to a greater or lesser extent, with his fellow peace officers.” Absent some express or implied promise to the contrary, he may also be charged with knowledge that “the probation officer is duty bound to report wrongdoing by the [probationer] when it comes to his attention, even if by communication from the [probationer] himself.”
Id.
at 432,
We therefore hold that custodial statements made to probation officers are subject to the same voluntariness analysis as statements made to other law enforcement officers.
Title 18 U.S.C. § 3501(b) sets forth the factors which a court must review to determine whether a confession is voluntary. These include:
(1) the time elapsing between arrest and arraignment of the defendant ..., (2) whether such defendant knew the nature of the offense with which he was charged or of which he was suspected at the time of making the confession, (3) whether or not such defendant was advised or knew that he was not required to make any statement and that any such statement could be used against him, (4) whether or not such defendant had been advised prior to questioning of his right to the assistance of counsel; and (5) whether or not such defendant was without the assistance of counsel when questioned and when giving such confession.
18 U.S.C. § 3501(b). The court must look at the totality of circumstances and the entire course of police conduct in determining vol-untariness.
Medeiros v. Shimoda,
The first factor clearly weighs in favor of voluntariness because Andaverde was questioned on the day he was arrested. The second factor also supports voluntariness because Andaverde knew the nature of the offense with which he was charged. A defendant need not be advised before he confesses
*1312
of the specific statute he is suspected of violating.
United States v. Williams,
The courts have generally rejected a
per se
rule as to when a suspect must be readvised of his rights after the passage of time or a change in questioners. In
Wyrick v. Fields,
the Supreme Court reversed the Eighth Circuit’s creation of a
per se
rule that
Miranda
warnings must be repeated after a suspect takes a polygraph exam, stressing that courts should look at the totality of the circumstances in each individual case.
A number of other circuits have also ruled that rewarning is not required simply because some time has elapsed. As the Fifth Circuit has noted, “[t]here is no requirement that an accused be continually reminded of his rights once he has intelligently waived them.”
United States v. Anthony,
On these facts, we see no qualitative difference between custodial questioning by a probation officer and questioning by another law enforcement officer. Thus, this case is very much like
Nordling.
As in
Nordling,
Andav-erde was
Mirandized
and then, almost immediately after being questioned by police, was questioned by another law enforcement officer, in this case Corrections Officer Keeth. Here, the two interrogations were an uninterrupted sequence of events. Schenck’s presence during Keeth’s questioning rendered the Keeth interrogation essentially a part of the police interrogation. Certainly, the two interrogations were so interconnected in time, subject matter, and by Schenck’s
*1313
presence that Andaverde must have known that his rights had not materially changed simply because he had been moved into a different room and faced a new interrogator.
See United States v. Hopkins,
B.
The district court also found that Andaverde’s statement to Keeth the next day, October 28, was voluntary. We agree.
The first statutory factor, time between arrest and arraignment, weighs in favor of voluntariness because the statement was made only one day after arrest so that it was not elicited by the pressures of lengthy confinement. The second factor also supports voluntariness, because Andaverde knew that he was being charged in connection with the firearm.
Keeth did not advise Andaverde of his rights before questioning him on October 28. However, Andaverde had been given a
Miranda
warning by the police shortly before he was interviewed by Keeth the preceding day. As previously discussed, a number of courts have held that an interval between a
Miranda
warning and a defendant’s statements does not nullify the warning. Indeed, one circuit has found that an interval of almost two weeks does not mandate new
Miranda
warnings.
Biddy v. Diamond,
IV.
Andaverde also contends that his statements to ATF Agent Wyatt should have been excluded at trial because he failed expressly to waive his
Miranda
rights. We review a defendant’s waiver of
Miranda
rights under the “clearly erroneous” standard.
United States v. Doe,
While a waiver of
Miranda
rights must be both intelligent and voluntary, the waiver need not be explicit.
North Carolina v. Butler,
The Seventh and Eighth Circuits, and a number of other circuits, have stated that a refusal to sign a waiver form does not show that subsequent statements are involuntary.
United States v. Kord,
The voluntariness of Andaverde’s statement is a close question under Heldt, but because this case is factually distinct, we hold that the district court’s admission of Andav-erde’s statements was not clearly erroneous.
V.
Andaverde next contends that the district court erred in admitting evidence pertaining to the sporting goods store burglary, which was the basis for the search warrant. First, Andaverde argues that the evidence did not meet the requirements of Fed.R.Evid. 404(b) for admissibility as other crimes evidence. Secondly, Andaverde argues that because his original burglary conviction in 1991 was before the jury, the evidence relating to this other burglary was unduly prejudicial. Whether testimony constituted “other crimes” evidence under Fed. R.Evid. 404(b) is a question of law which we review de novo.
United States v. Soliman,
A review of the record shows that the references to the burglary were not extensive. One police officer testified that:
There had been a burglary of a business on Lincoln Avenue in Sunnyside. Several items had been taken from the business. Myself and Detective Sehenck responded to that burglary scene. While there, we were informed of some information by a couple of patrol officers that were there. Based on their information and things that we observed, Detective Sehenck ultimately requested and obtained a search warrant for a residence to recover items believed to have been taken.
A second police officer, Detective Sehenck, also referred to the burglary as being the reason for obtaining the search warrant for *1315 Andaverde’s home. The record shows that the references to the sporting goods store burglary supplied background for the police’s behavior and were not so prejudicial that it was an abuse of discretion for the district court to have admitted the evidence.
VI.
In light of our recent decision in
United States v. Cruz,
VII.
We affirm the district court’s ruling that prosecution of Andaverde under 18 U.S.C. § 922(g)(1) does not violate the Fifth and Tenth Amendments, and that the statute applied to Andaverde as a convicted felon because his civil rights had not been substantially restored. We also affirm the district court’s ruling as to the voluntariness of An-daverde’s statements to his probation officer and the ATF agent. We affirm the district court’s admission of evidence of the burglary under Fed.R.Evid. 408. Lastly, we reverse Andaverde’s conviction under 18 U.S.C. § 922(j) for receiving a stolen firearm, because of our recent opinion in United States v. Cruz.
AFFIRMED in part, REVERSED in part.
Notes
. The officers were searching for evidence relating to the burglary of a sporting goods store.
. The record is unclear as to the actual time gap between the Miranda warning and Keeth's questioning of Andaverde. At the voluntariness hearing, Keeth estimated that the gap was "two hours at the very most.” However, according to Schenck, his interrogation of Andaverde lasted about half an hour, and there was at most a ten minute time period between the interrogations, which would make the interval between the Miranda warning and Keeth's questioning under an hour.
. On direct examination, Detective Schenck testified as follows:
Q: What happened after you interviewed him?
A: Once I was done interviewing him, I walked him out of my office. Sitting directly outside of my office was Spurgeon Keeth.
Q: Okay. Tell the jurors what happened.
A: I told Spurgeon Keeth that I was done taking a statement from him; that I had Mir-andized him. He understood his rights, and then I told him he could talk to Gabriel. At that time he started talking—you know, Gabriel and Spurgeon started talking—and I kind [?] off to the side and listened for a little while.
I didn’t record the exact specifics, but what I heard was just basically—
. On January 31, 1993, the date of Andaverde's federal conviction, Washington state law only prohibited him from possessing short firearms and pistols. Wash.Rev.Code § 9.41.040. This statute was amended in July 1994 to prohibit persons convicted of a serious offense from possessing any firearm.
See United States v. Herron,
. Andaverde argues that his lack of mental acuity and education should also be taken into account in determining whether his statements were voluntary. Although Andaverde has been adjudged mentally competent, the record shows that he is mentally "slow” and does not always understand instructions. Furthermore, Andaverde has only a tenth-grade education. The district court reduced Andaverde's sentence for diminished mental capacity.
Low intelligence level and lack of education must he taken into account when determining the voluntariness of confessions.

court considered the same version of this statute as involved in this case.
