The issue on this appeal is whether a probationer who provides incriminating information to his probation officer in response to questions from that officer, and does so pursuant to a probation condition that requires him to “promptly and truthfully answer all reasonable inquiries” from the officer or face revocation of his probation, is “compelled” to give incriminating evidence within the meaning of the Fifth Amendment. Because we conclude that the state took the “impermissible step” of requiring the probationer “to choose between making incriminating statements and jeopardizing his conditional liberty by remaining silent,” Minnesota v. Murphy, 465 U.S. 420, 436, 104 S.Ct. 1136, 79 L.Ed.2d 409 (1984), we hold that his admission of criminal conduct was compelled by a “classic penalty situation” and the evidence obtained by the probation officer may not be used against him in a criminal proceeding. We therefore affirm the district court’s order suppressing the fruits of the state’s unlawful conduct.

Phata Saechao pled guilty to a state felony offense and was sentenced to state probation. The felony, which involved an act of domestic violence, was his first. The day after his plea, Saechao met with his intake officer, Heather Fowler, to review the conditions of his probation. Condition number 11 required Saechao to “promptly and truthfully answer all reasonable inquiries by the Department of Correction or County Community Correction Agencies,” and condition number 12 prohibited him from possessing “weapons, firearms, or dangerous animals.” The terms of his probation also provided that failure to comply with any of the conditions was grounds for arrest, revocation of probation, or modification of conditions. Sae-chao signed the probation form, but was not asked by Fowler at the time whether he possessed a firearm. After the intake meeting, Saechao was told to call the domestic violence unit to report to his assigned probation officer within a week’s time.
After the intake meeting, Saechao was assigned to Probation Officer Andrew Altman of the domestic violence unit for the supervision of his probation. Saechao attempted to contact Altman several times over the next month and finally had his first meeting with Altman over a month after his initial intake interview with Fowler. According to Altman’s testimony, the meeting was designed to “figure out the personal needs of [the probationer] ..., [to] try and assess the compliance with the conditions of supervision, [to] make sure [the probationer is] very clear about what the conditions are, [to] review them again, ... [and to] get [his] expectations to them.”
Altman began the meeting by reviewing once again the conditions of Saechao’s probation, including the requirement that Sae-chao “promptly and truthfully answer” Altman’s inquiries. Altman then began the interview, during which he repeatedly asked whether Saechao possessed a firearm. As a result of Altman’s questioning, Saechao eventually acknowledged that there was a 30.06 hunting rifle that he used for deer hunting in the apartment that he shared with his parents, a rifle that *1076he possessed legally prior to the time of his conviction. Possession of the firearm became illegal under the felon-in-possession statute upon Saechao’s felony conviction. See 18 U.S.C. § 922(g)(1). Altman later testified that it was clear from the interview that Saechao had been concerned about the rifle even before the meeting, but that he “didn’t know what to do with the firearm. He had paid money for the firearm. It was worth money, and he hadn’t made a decision what to do with it at [that] point.”
After Saechao’s admission of “possession,” Altman explained the seriousness of his conduct and convinced Saechao to accompany him and Probation Officer Matthew Ferguson back to the apartment Sae-chao shared with his parents so that the officers could remove the rifle. After speaking with his parents, Saechao directed the officers to a room where Altman and Ferguson confiscated an unloaded 30.06 hunting rifle from underneath the mattress. Altman and Ferguson then left. Saechao was not arrested at the time.
Altman later discussed the case with his supervisor and decided that instead of excusing Saechao’s violation, or even pursuing a revocation of probation, they would turn the evidence over to the federal authorities so that they could initiate a federal prosecution against him for possession of a firearm by a convicted felon. Altman acknowledged that the referral to federal authorities was not routine.1 A month later, the federal authorities arrested Sae-chao and charged him with being a felon in possession of a firearm in violation of 18 U.S.C. § 922(g)(1).
The district court granted Saechao’s motion to suppress his statements to Altman. It found that Saechao “did not have free choice to refuse to answer questions about firearms precisely because those questions related to a specific condition of his probation.” United States v. Saechao, No. CR 03-447-RE (D.Or. Mar. 5, 2004) (opinion and order granting the defendant’s motion to suppress statements). Thus, the district court concluded, the statements were “compelled,” in violation of the Fifth Amendment to the United States Constitution. The United States appeals the suppression order.
III.
We must determine whether Saechao was compelled by threat of penalty to answer his probation officer’s questions regarding his possession of firearms. In Murphy, the Supreme Court explained that if a state attaches “[t]he threat of punishment for reliance on the privilege” against self-incrimination by asserting either “expressly or by implication ... that invocation of the privilege would lead to revocation of probation ... the probationer’s answers would be deemed compelled and inadmissible in a criminal prosecution.” Id. at 435, 104 S.Ct. 1136 (emphasis added). Because the state of Oregon took the “impermissible step” of “requir[ing] [Saechao] to choose between making incriminating statements and jeopardizing his conditional liberty by remaining silent,” we hold that Saechao’s statements were compelled and therefore inadmissible in the ensuing criminal prosecution. Id. at 436, 104 S.Ct. 1136.
*1077As a general rule, “the [Fifth] Amendment speaks of compulsion.... If [an individual] desires the protection of the privilege, he must claim it or he will not be considered to have been ‘compelled’ within the meaning of the Amendment.” Id. at 427, 104 S.Ct. 1136 (quoting United States v. Monia, 317 U.S. 424, 427, 63 S.Ct. 409, 87 L.Ed. 376 (1943) (first alteration in original) (internal quotation marks omitted)). There are, however, exceptions to this rule. The Court has held that if an individual is subjected to a practice that “den[ies him] ... a ‘free choice to admit, to deny, or to refuse to answer,’ ” then any statement he makes is considered involuntary and cannot be used in a criminal proceeding. Garner v. United States, 424 U.S. 648, 657, 96 S.Ct. 1178, 47 L.Ed.2d 370 (1976) (quoting Lisenba v. California, 314 U.S. 219, 241, 62 S.Ct. 280, 86 L.Ed. 166 (1941)). In these cases, the Fifth Amendment is considered “self-executing,” and an individual does not need to invoke it in order to have his admissions suppressed in an ensuing criminal prosecution. Murphy, 465 U.S. at 435, 104 S.Ct. 1136.
One instance in which an individual is held to have been denied the free choice to admit, to deny, or to refuse to answer is what the Court refers to as a “penalty situation.”2 Id. If an individual’s refusal to answer incriminating questions subjects him to a penalty, then the Fifth Amendment is self-executing and any statements made under threat of such penalty are inadmissible.3 In the probationary context, this means that although the state is permitted to require a probationer to “appear and discuss matters affecting his probationary status,” the probationer may not be required under threat of revocation of probation to respond to “questions put to [him], however relevant to his probationary status, [that] call for answers that would incriminate him in a pending or later criminal proceeding.” Id. The key to whether the Fifth Amendment is self-executing in probation cases lies in the following statement by the Court: “[I]f the State, either expressly or by implication, asserts that invocation of the privilege would lead to revocation of probation, it would have created the classic penalty situation, the failure to assert the privilege would be excused, and the probationer’s answers would be deemed compelled and inadmissible in a criminal prosecution.” Id. (emphasis added). As the Supreme Court explained, in order for a court to determine whether a probationer is subject *1078to a penalty situation, it “must inquire whether [his] probation conditions merely required him to appear and give testimony about matters relevant to his probationary status or whether they went further” by taking “the extra, impermissible step” of requiring him “to choose between making incriminating statements and jeopardizing his conditional liberty by remaining silent.” Id. at 436, 104 S.Ct. 1136.
Although the Supreme Court in Murphy set forth the governing legal standard for a classic penalty situation, it ultimately found that Murphy’s admission was not compelled under threat of penalty because of the particular nature of his probation conditions. The Supreme Court first found that Murphy’s probation conditions did not actually require him to answer his probation officer’s inquiry. Id. at 437, 104 S.Ct. 1136. The Court noted that Murphy’s conditions required him only to “be truthful with his probation officers in all matters,” and did not impose any affirmative obligation to respond to his probation officer’s questions: “On its face, [the] probation condition proscribed only false statements; it said nothing about his freedom to decline to answer particular questions. ...” Id. at 436, 437, 104 S.Ct. 1136. In light of the limitations of Murphy’s probation condition, and the state’s subsequent insistence that “it would not, and legally could not,” on the basis of a “be truthful” condition, “revoke probation for refusing to answer questions calling for information that would incriminate in separate criminal proceedings,” the Court concluded that Murphy could not have been objectively or subjectively “deterred from claiming the privilege by a reasonably perceived threat of revocation.” Id. at 438-39, 104 S.Ct. 1136. Unlike in the case of Murphy, Saechao was compelled by threat of penalty to answer the probation officer’s inquiry about firearms. The terms of his probation compelled him to answer “all reasonable inquiries.”4 The Oregon probation condition at issue was, thus, categorically different from the “be truthful” condition in Murphy. See Murphy, 465 U.S. at 422, 104 S.Ct. 1136. Not only was Saechao required to be truthful to his probation officers, but he was expressly required, under penalty of revocation, to “promptly ... answer all reasonable inquiries.” Contrary to the government’s contentions, there is a significant difference between being required to be “truthful with ... probation officer in all matters,” Murphy, 465 U.S. at 422, 104 S.Ct. 1136 (internal quotation marks omitted), and being required to “promptly and truthfully answer all reasonable inquiries.” Whereas the former “sa[ys] nothing about [a probationer’s] freedom to decline to answer particular questions” and “proscribe[s] only false statements,” the latter specifically penalizes a refusal to “answer particular questions.” Murphy, 465 U.S. at 437, 104 S.Ct. 1136. In contrast to Murphy, who the Supreme Court found was free to remain silent as long as he was truthful when he spoke, Saechao did not have the luxury of remaining silent without violating the conditions of his probation. Failure to answer a relevant inquiry regarding the conditions of probation would have justified the revocation of his probation.
The government argues that a probationer is subject to threat of penalty only when the state explicitly announces that it *1079will impose a penalty for the invocation of his Fifth Amendment rights — that an announcement that it will punish him for any failure to answer a question is not sufficient. In order to violate Murphy, the government asserts, Oregon must specifically state to the probationer: “we will revoke your probation if you invoke your Fifth Amendment privilege.” We reject the government’s argument. Not only is it contrary to the plain language of the Supreme Court’s decision in Murphy, but also to the Oregon state court’s interpretation of its own probation conditions.
Murphy held that a penalty situation is created if there is a “reasonable basis for concluding that [the state] attempted to attach an impermissible penalty to the exercise of the privilege against self-incrimination.” Id. at 437. Murphy also explained that a state creates a classic penalty situation if it “expressly or by implication ” suggests “that invocation of the privilege would lead to revocation of probation.” Id. at 435, 104 S.Ct. 1136 (emphasis added). Here, Saechao was required, as a condition of his probation, to “promptly and truthfully ansiuer all reasonable inquiries.” In requiring answers to all such inquiries, the condition makes no exception for the invocation of the Fifth Amendment and, thus, by implication forecloses a probationer’s ability to exercise that right by remaining silent. In light of the particular conditions applicable to Oregon probationers, there is certainly a reasonable basis under Murphy for a probationer to conclude that, although the invocation of the Fifth Amendment is not explicitly prohibited, an exercise of that right by invoking the privilege or simply by remaining silent would constitute grounds for revocation of probation.
The government’s argument also runs counter to the interpretation of Oregon’s probation conditions by the Oregon state courts.5 In State v. Gaither, 196 Or.App. 131, 100 P.3d 768, 769 (2004), rev. denied, 113 P.3d 435 (Or.2005), the Oregon Court of Appeals held that statements elicited by a probation officer were “compelled” even though there was no express reference to the Fifth Amendment privilege in the probation conditions. The probationer in Gaither was not specifically informed that under the terms of his Oregon probation he could be punished if he asserted his right to remain silent, and he was not specifically threatened with probation revocation or other penalties if he invoked the privilege. Nevertheless, addressing probation conditions that required the defendant to “promptly and truthfully answer all reasonable inquiries” and “fully disclose his sexual history and provide a list of all ... prior victims,” the state court held that the probationer was given an impermissible choice in violation of Murphy. Id. at 770, 772-73. In so finding, the Oregon court implicitly held both that an express declaration that the probationer may not invoke the Fifth Amendment is not required, and that an invocation of the privilege does not constitute compliance with Oregon’s probation conditions. It concluded that under the terms of his probation, Gaither “had no choice other than to disclose or face revocation of probation.” Id. at 772. In so doing, the Oregon court necessarily determined that Oregon “legal*1080ly could ... revoke probation for refusing to answer questions calling for information that would incriminate in separate criminal proceedings.” Murphy, 465 U.S. at 438, 104 S.Ct. 1136.6
The government next puts a slightly different twist on its basic argument by asserting that even if Oregon’s probation conditions foreclosed Saechao’s ability simply to remain silent, and required him to answer the probation officer’s inquiry, Sae-chao could have satisfied the conditions by “promptly answerpng] the question by invoking the privilege, or promptly askfing] for clarification, or promptly seeking] legal advice on whether the privilege applies.” We reject this creative recasting of its argument.
The government’s contention is based on an incorrect reading of the probation condition at issue. Saechao was required to “promptly and truthfully answer all reasonable inquiries.” The condition did not simply require a prompt statement of some kind — such as a statement setting forth a reason for not answering the question. Rather, the condition expressly requires an answer to the question being asked. A verbal invocation of the right to remain silent followed by the act of not responding to incriminating questions is, by definition, not answering a question, let alone providing a prompt and truthful answer. A refusal to answer, even if it could somehow be called an answer, constitutes neither a truthful nor an untruthful response. It is non-substantive in nature. For that reason alone, invoking the privilege, asking for clarification, or seeking legal advice, could not satisfy the requirement for a prompt and truthful answer.
The Eleventh Circuit, confronted with a nearly identical probation condition, explicitly rejected the argument that by “answering” a probation officer’s inquiry with an invocation of the Fifth Amendment, the probationer would comply with an obligation to answer or respond to his probation officer’s inquiries and thereby avoid a revocation of his probation. In United States v. Robinson, 893 F.2d 1244 (11th Cir.1990), the court considered a federal probation condition that required probationers to “report and to give an account of [himself] and to respond completely and *1081truthfully to questions asked by the probation officer.” Id. 1244-45 (alteration in original) (internal quotation marks omitted) (emphasis added). When Robinson was asked a question that required an incriminating response, he followed the course of conduct proposed by the government in this case and invoked the Fifth Amendment. See id. at 1244. That invocation, however, promptly led the government to seek the revocation of Robinson’s probation, which the district court granted and the Eleventh Circuit affirmed. See id. at 1244-45. Interpreting the condition in the manner there requested by the government, the Eleventh Circuit held that invoking the Fifth Amendment did not constitute a response to a question, but rather was “a refusal to answer that violated an express condition of probation.” Id. at 1245 (quoting Murphy, 465 U.S. at 435 n. 7, 104 S.Ct. 1136). The Eleventh Circuit ruled that by asserting the privilege the probationer failed to comply with the condition requiring him to answer his probationer officer’s inquiries, and “that such failure alone can justify revocation of probation.” Id. (quoting United States v. Morin, 889 F.2d 328, 332 (1st Cir.1989)).
In light of the Eleventh Circuit’s holding in Robinson and that circuit’s acceptance of the United States’ position that invoking the Fifth Amendment does not constitute compliance with a condition similar to that at issue here, we reject its assertion of the contrary argument in this case. We find it troubling that the United States, having successfully sought revocation of probation in the past for the very conduct that it suggests Saechao should have engaged in here, now assures us unabashedly that such conduct would not justify the revocation of Saechao’s probation.
In sum, we hold that the district court did not err in suppressing the fruits of the state’s impermissiblv coercive penaltv threat. Saechao was indeed “compelled” to incriminate himself under threat of probation revocation. He was instructed on two occasions that his probation conditions required him, inter alia, to “promptly and truthfully answer all reasonable inquiries” and the terms of his probation provided that a failure to comply could result in its revocation. Moreover, the state did not advise him that “it would not, [or] legally could not, revoke probation for refusing to answer questions calling for information that would incriminate in separate criminal proceedings.” Murphy, 465 U.S. at 438, 104 S.Ct. 1136. To the contrary, the state court’s holding in Gaither (as well as the ruling that the government elicited from the Eleventh Circuit in Robinson) confirms that such a revocation is possible and could be pursued by the state. Thus, we conclude that, unlike in Murphy, the probation conditions in this case constitute an attempt by the state “to attach an impermissible penalty to the exercise of the privilege against self-incrimination.” Id. at 437, 104 S.Ct. 1136. The evidence obtained in this case was properly suppressed by the district court.
IV.
The Fifth Amendment proscribes the use in a separate criminal proceeding of a statement obtained pursuant to a probation condition that requires a probationer to “choose between making incriminating statements and jeopardizing his conditional liberty by remaining silent.” Id. at 436, 104 S.Ct. 1136. If, by virtue of its probation conditions, a state expressly or implicitly penalizes the exercise of the right to remain silent, then the probationer’s answers to incriminating questions posed by his probation officer are deemed compelled and are inadmissible in ensuing criminal proceedings. See id. at 435, 104 S.Ct. 1136. Oregon's probation conditions *1082provide for precisely such a penalty. Accordingly, we affirm the district court’s decision to suppress the evidence obtained as a result of Saechao’s inculpatory responses to his probation officers’ inquiries.
