Defendant appeals his convictions for interference with interstate commerce by robbery, aiding and abetting the robbery, and aiding and abetting the killing of Mrs. Barbara Sun. The charges against Defendant stem from his involvement in the robbery of the Mandarin Restaurant and Lounge in Wichita, Kansas, and the murder of Mrs. Sun on November 8, 1994. Mrs. Sun owned and operated the restaurant with her husband, Mr. Mark Sun. Defendant, accompanied by three co-defendants, entered the Mandarin to initiate the robbery. While two of the co-defendants tied up Mr. Sun and a waiter, Defendant and co-defendant Mr. Bountaem Chanthadara took Mrs. Sun upstairs. Mrs. Sun was beaten and shot five times. She died that evening from multiple gunshot wounds. Following the robbery and the murder of his wife, Mr. Sun closed the restaurant for twenty-two days. The restaurant reopened for six months before it permanently closed in June 1995.
*1222 On January 4, 1996, Defendant was charged in a superseding indictment with two counts: (1) interference with interstate commerce by robbery in violation of 18 U.S.C. § 1951 [Hobbs Act], and aiding and abetting the robbery in violation of 18 U.S.C. § 2; and (2) carrying and using a firearm during and in relation to the robbery in violation of 18 U.S.C. § 924(c)(1), causing the death of a person through the use of a firearm, which constitutes murder under 18 U.S.C. §§ 924(f)(1) & 1111(a), and aiding and abetting the killing of Mrs. Sun in violation of 18 U.S.C. § 2. The district court denied Defendant’s motions to suppress statements and to dismiss Count 2, and a jury convicted Defendant on both counts. The jury convicted Defendant under Count 2 for aiding and abetting the murder of Mrs. Sun. Defendant was sentenced to 240 months imprisonment on Count 1 and life imprisonment without the possibility of release on Count 2, to be served concurrently. Defendant raises several issues on appeal.
I. Voluntariness of Defendant’s Statement
Defendant argues that his Fifth Amendment rights were violated by the district court’s erroneous admission of his post-arrest statement to the FBI in which he confessed involvement in the robbery. He asserts that the statement was involuntary because it was conditioned on assurances of favorable treatment and leniency, however slight. After a hearing, the district court found that Defendant’s statement was voluntary and denied his motion to suppress.
In reviewing a district court’s denial of a motion to suppress a statement or confession, we accept the district court’s underlying factual findings unless they are clearly erroneous.
See United States v. Roman-Zarate,
Several factors indicate that Defendant’s statement was given voluntarily. Defendant testified at the suppression hearing that he was advised of his
Miranda
rights and that he understood those rights before making his statement. He admitted that he initialed the waiver of rights form and conceded that the FBI agent neither threatened him nor used physical force against him.
See Muniz,
At the suppression hearing, Defendant testified that his confession was coerced because the FBI agent told him about the penalties he would face and indicated that he might receive lenient treatment if he cooperated. FBI Agent Wenko, however, testified at the suppression hearing that he did not make any offers of assistance or leniency and did not discuss possible sentences with Defendant. Agent Wenko also stated that no one else made such statements in his presence. In attempting to resolve this discrepancy and determine the credibility of the witnesses, the district court found both Defendant and Agent Wenko credible. “[I]nso-far as the discrepancy [was] concerned,” however, the court found the FBI agent’s “testimony to be more credible, primarily because so much of [it] was corroborated by [Defendant.” R., Yol. II, Doe. 123 at 7.
Defendant argues that the court’s credibility determination was erroneous because Agent Wenko changed his testimony at trial and, therefore, Defendant’s own testimony at the suppression hearing is more credible. At trial, Agent Wenko testified that he neither discussed the length of a sentence with Defendant nor made any statements about informing the prosecutor or judge if Defendant cooperated. This testimony is consistent with Agent Wenko’s testimony at the suppression hearing. Agent Wenko also testified at trial that another FBI agent present at the interview, Agent Flosnick,
may
have made statements about cooperation or length of sentence. This trial testimony represents that Agent Wenko could not testify, of his own knowledge, that nobody else made such statements. The agent’s trial testimony is sufficiently consistent with his prior testimony at the suppression hearing that it does not constitute newly discovered evidence, even if it is slightly different than his suppression hearing testimony. In any ease, a statement to inform the prosecutor of a defendant’s cooperation without any other indications of coercion does not constitute a promise of leniency.
See Roman-Zarate,
II. Sufficiency of the Evidence
Defendant argues that the evidence was insufficient to convict him on both Count 1 and Count 2. We review the sufficiency of the evidence
de novo,
viewing the evidence and the inferences therefrom in a light most favorable to the government to determine if a reasonable jury could find beyond a reasonable doubt that the defendant was guilty.
See United States v. Voss, 82
F.3d 1521, 1524-25 (10th Cir.),
cert. denied,
— U.S. -,
*1224
Defendant argues that the government did not satisfy the requirements of the Hobbs Act in Count 1 because the evidence did not demonstrate that the robbery affected interstate commerce. The Hobbs Act is implicated if someone “in any way or degree obstructs, delays, or affects commerce or the movement of any article or commodity in commerce, by robbery or extortion or attempts or conspires to do so.” 18 U.S.C. § 1951(a). After the Supreme Court’s decision in
United States v. Lopez,
During trial, the government presented evidence which showed that the Mandarin Restaurant was a business engaged in interstate commerce and that its assets were depleted by the robbery. Mr. Sun testified that, before the robbery, the restaurant had often purchased specialty food products from vendors in California, Missouri, and Oklahoma, and that the money stolen by Defendant would have been used to purchase more of those items. He testified that the restaurant purchased fewer out-of-state items after the robbery, in part because it closed for twenty-two days and also because business decreased significantly after it reopened due to customers’ fears about dining at the restaurant. Mr. Sun also testified that purchases by customers using out-of-state credit cards declined after the robbery. According to Mr. Sun’s testimony, the business eventually failed as a result of the robbery because he could not run the restaurant himself, attract customers, or generate revenue, and, therefore, he could not purchase supplies in interstate commerce for the restaurant. An FBI agent confirmed Mr. Sun’s statements, testifying that credit card sales declined and business revenues decreased after the robbery. We conclude that the record evidence and the inferences therefrom demonstrated the requisite effect on interstate commerce.
Defendant claims that the murder of Mrs. Sun, which was committed during the robbery, should not be considered as proof of the effect of the robbery on interstate commerce. The government may show the effect-on-commerce requirement not only by the effect of stolen money on interstate commerce but also by evidence showing an “interference
‘in any way
or
degree
’ ... by robbery or extortion.”
United States v. Boston,
Testimony relating to the murder committed during the course of the robbery of the Mandarin is no different from this hypothetical testimony, even if the murder constitutes a separate crime. Mr. Sun’s testimony and other evidence recited above indicates that a nexus existed between the loss of the business and Mi’s. Sun’s death. Her murder, committed during the course of the robbery, was a consequence of the robbery that could be considered for its effect on interstate commerce. Testimony indicating that fewer customers patronized the restaurant after the robbery and murder, that Mr. Sun could not run the business by himself without the assistance of his wife, and that business steadily declined until Mr. Sun had to close his restaurant constitutes appropriate evidence showing the robbery’s impact on interstate commerce.
The money stolen from Mrs. Sun’s purse also could legitimately be considered for its effect on interstate commerce. The money was stolen during the course of the robbery of the restaurant. It was taken from Mrs. Sun’s purse which was located inside the restaurant and which belonged to the co-owner and operator of a business engaged in interstate commerce. The aggregate impact of the theft of the restaurant money, the decline in credit card sales and business revenue, and the temporary closing after the robbery, the murder of Mrs. Sun, and the money stolen from her purse establishes more than a minimal nexus to interstate commerce.
See Wickard v. Filburn,
Defendant also contends that the evidence was insufficient to convict him of aiding and abetting the murder of Mrs. Sun in Count 2. He argues that, although he intended to commit the robbery, the government failed to prove malice aforethought, the level of intent necessary to prove murder and aiding and abetting murder under 18 U.S.C. §§ 2 & 1111(a). He asserts that there was no proof that he planned or intended to murder anyone or that he encouraged his co-defendant to kill Mrs. Sun.
One is guilty of violating 18 U.S.C. § 924(j)(l)
1
if he caused the death of a person while using a firearm to commit a crime of violence in violation of section 18 U.S.C. § 924(c)(1). The evidence unequivocally showed that co-defendant Mr. Chanthadara violated 18 U.S.C. § 924(j) by shooting Mrs. Sun during the course of the robbery. This killing constitutes a felony murder under 18 U.S.C. § 1111(a). The statute defines murder as the “unlawful killing of a human being with malice aforethought,” and characterizes felony murder as first degree murder which is “[e]very murder ... committed in the perpetration of, or attempt to perpetrate, any [of the listed felonies].” 18 U.S.C. § 1111(a);
see United States v. Kayarath,
The essence of Defendant’s argument is that the government must establish some proof of state of mind other than the intent to commit the robbery and the fact that the killing occurred during the commission of the robbery. The federal murder statute’s definition of felony murder does not require the government to prove any intent other than that the killing was committed in the course of the underlying felony.
See
18 U.S.C. § 1111(a). Therefore, in this case, once the government has shown that Defendant intended to commit the robbery and that a killing occurred in the course of that robbery, no additional proof of state of mind is necessary. This analysis is supported by our statements in
Montoya
and is not inconsis

Sides. See Montoya,
In this case, the evidence before the jury undoubtedly showed the requisite intent for a conviction under Count 2. The record indicates that Defendant admitted to participating in the armed robbery which resulted in the killing of Mrs. Sun. The government did not need to show that Defendant had any specific intent to kill Mrs. Sun. We emphasize that the government also presented sufficient evidence that Defendant aided and abetted the killing of Mrs. Sun. The record indicates that Defendant held Mrs. Sun at gunpoint, brought her upstairs, and beat her. Defendant committed these acts knowing that his co-defendant, Mr. Chanthadara, was armed, was present in the room where Defendant beat Mrs. Sun, and was often violent and uncontrollable. These facts show that Defendant initiated and participated in the assault which led to the death of Mrs. Sun even though he was aware of his co-defendant’s propensity for violence. The evidence also shows that Defendant did not leave the room after he beat Mrs. Sun but was present when his co-defendant shot her five times and that Defendant and co-defendant Mr. Chanthadara came downstairs and left the restaurant together. It is reasonable to infer from this evidence that Defendant’s participation in the robbery and in the assault on Mrs. Sun incited or encouraged his co-defendant’s murder of Mrs. Sun. We affirm Defendant’s conviction on Count 2 because the record contains abundant evidence to enable a jury to find beyond a reasonable doubt that Defendant intended to commit the underlying felony, that Mrs. Sun was killed during the commission of that felony, and that Defendant aided and abetted that killing.
III. Constitutionality of 18 U.S.C. § 924(c) & (j)(l) 2
Defendant asserts that his conviction on Count 2 should be reversed because Congress exceeded its authority under the Commerce Clause in enacting 18 U.S.C. § 924(c)
&
(j)(l). Defendant, citing the Supreme Court’s decision in
Lopez,
Section 924(j)(l) reads:
A person who, in the course of a violation of subsection (c), causes the death of a person through the use of a firearm, shall- ... if the killing is a murder (as defined in section 1111), be punished by death or by imprisonment for any term of years or for life.
To be convicted of aiding and abetting a murder in violation of section 924(j)(l), Defendant must have first violated section 924(c)(1) by using or carrying a firearm during and in relation to a crime of violence. That requirement has been met because we held above that the evidence supported the crime of violence, an armed robbery, and its impact on interstate commerce under the Hobbs Act. This court has upheld the constitutionality of the Hobbs Act in the face of a Commerce Clause challenge.
See Bolton,
We also uphold the constitutionality of 18 U.S.C. § 924(j). In this case, the robbery represents the crime of violence which is a necessary element of the section 924(j) offense charged in Count 2. Because Defendant’s section 924(J) conviction is predicated on his conviction under the Hobbs Act for an armed robbery that affected interstate commerce, we reject his
Lopez
challenge to section 924(j).
See United States v. Lopez,
IV. Jury Instructions
Defendant argues that the district court’s jury instructions were improper and misled the jury. We review a district court’s decision whether to give a particular instruction for abuse of discretion.
See United States v. Swallow,
Defendant contends that the court erred in refusing to instruct the jury that it could not consider the effect on interstate commerce of both the murder of Mrs. Sun and the money stolen from Mrs. Sun’s purse. We reject this challenge for two reasons. First, we determined above that evidence of Mrs. Sun’s murder was appropriately considered in determining whether the robbery had an effect on interstate commerce under the Hobbs Act. As we previously stated, her death is a consequence of the robbery which could be considered for its impact on interstate commerce. Second, the jury also could appropriately consider the money stolen from Mrs. Sun’s purse for its impact on interstate commerce. The money was stolen during the course of the robbery of the restaurant from Mrs. Sun’s purse located inside the restaurant. More importantly, the money was stolen from the purse that belonged to an owner and operator of a business engaged in interstate commerce. These facts distinguish the cases relied on by Defendant,
United States v. Quigley,
Defendant also contends -that the district court erroneously instructed the jury *1228 that his actions, i.e., the robbery, could have a “potential” or “probable” effect on interstate commerce rather than an actual effect. Appellant’s Opening Br. at 45. The court instructed the jury that the government must establish beyond a reasonable doubt that “[a]s a result of the defendant’s actions, interstate commerce, or an item moving in interstate commerce, was actually or potentially delayed, obstructed, or affected in any way or degree.” R., Vol. Ill, Doc. 189 at Instr. No. 9. The court also instructed:
If you find that the defendant intended to take certain actions — that is, he did the acts charged in the indictment in order to obtain property — and you find those actions have either caused, or would probably cause, an effect on interstate commerce, then you may find the requirements of this element have been satisfied.
Id. at Instr. No. 11. The court stated that Defendant did not need to intend to affect interstate commerce but that the effect on interstate commerce may be a natural consequence of his actions. Id.
The use of the words actual, potential, and probable explain to the jury the type of effects on interstate commerce that the government must show to meet the jurisdictional requirement under the Hobbs Act. These words represent the kind of aggregate or cumulative impact that is the linchpin of the interstate commerce nexus established in
Wickard,
We have held that a depletion of assets potentially affecting interstate commerce constitutes a sufficient nexus to interstate commerce under the Hobbs Act.
See Zeigler,
The use of the word “probable” in the instructions also represents to the jury its ability to make a determination based on the likelihood that the robbery affected interstate commerce.
Cf. Zeigler,
The government correctly points out that this court approved a jury instruction in which the government was required to prove that the defendant “actually or potentially obstructed, delayed, or affected interstate commerce or attempted to do so.”
Boston,
Finally, Defendant asserts that the court's instruction on malice aforethought “prejudicially collapsed the separate elements of ‘robbery’ and ‘malice’ into a single element” for Count 2. Appellant’s Opening Br. at 47. The court instructed the jury that “[a] killing is done with malice aforethought when it is done deliberately and with the intent to kill another person, or if it results from the commission of a robbery.” R., Vol. Ill, Doe. 189 at Instr. No. 17. The latter part of this instruction essentially parallels the definition of felony murder under 18 U.S.C. § 1111(a): “Every murder ... committed in the perpetration of, or attempt to perpetrate, any [listed felony such as a robbery].”
As in his sufficiency of the evidence argument, Defendant claims that, to be convicted of Count 2, the government must present proof of his state of mind which is in addition to and separate from his intent to commit the underlying felony and the proof that a killing occurred during the commission of that felony. In accordance with our discussion above, Defendant’s argument has no merit. The statute does not require any proof of intent other than that Defendant intended to commit the underlying felony and that the killing was committed in the course of that felony. Therefore, a charge of felony murder does not entitle Defendant to an instruction requiring additional or independent proof of state of mind. The instruction in this case comports with the felony murder definition that all killings committed in the perpetration of a robbery constitute first degree murder.
See
18 U.S.C. § 1111(a);
Montoya,
Defendant’s claims are also supplanted by the court’s separate instructions to the jury which described what the government must show to establish that Defendant aided and abetted the killing of Mrs. Sun, see id. at Instr. No. 18, and which articulated the elements of a robbery, a Hobbs Act crime, and a violation of 18 U.S.C. § 924(c), see id. at Instr. Nos. 8, 13-15. Further, the court explained the distinct elements that the government must prove to sustain its burden of proof in Count 2. See id. at Instr. No. 16. We believe that the instructions as a whole properly defined the state of mind required to prove a violation of 18 U.S.C. § 924(j)(l) and felony murder and did not prejudice Defendant.
Defendant’s convictions are AFFIRMED.
Notes
. The statute under which Defendant was charged and convicted, 18 U.S.C. § 924(i)(l), has been changed to 18 U.S.C. § 924(j)(l). For the sake of future clarity, we refer to section 924(i) as section 924(j).
. As we noted previously, section 924(j) is the former section 924(i) cited by the parties in their briefs.
. Defendant's argument that the use of the potential or probable language is limited to extortion or attempt cases is invalid in light of our approval in
Zeigler
of the potential "depletion of assets” effects on interstate commerce.
Zeigler
was not an attempt or extortion case but involved multiple completed robberies.
