A grand jury indicted Defendant Anthony Serrano, a felon, on various firearms charges after law enforcement seized a 30.06 rifle from his home and a sawed-off shotgun from his vehicle. At trial, Defendant claimed he did not knowingly possess either the rifle or shotgun. An unpersuaded jury convicted Defendant of: (1) being a felon in possession of a sawed-off shotgun in violation of 18 U.S.C. § 922(g)(1) (“count. I”); (2) knowingly possessing a sawed-off shotgun not registered in the National Firearms Registration and Transfer Record in violation of 26 U.S.C. § 5861(d) (“count II”); and (3) being a felon in possession of a 30.06 rifle in violation of 18 U.S.C. § 922(g)(1) (“count III”). The district court sentenced Defendant to 262 months imprisonment. Defendant appeals, arguing (1) the coercive and intimidating conduct of the district judge and prosecutor dissuaded two of his witnesses from testifying in violation of his constitutional right to present a defense, (2) the district court erred in refusing to grant his two witnesses immunity after they invoked the privilege against self incrimination, and (3) the district court unconstitutionally increased his sentence under the United States Sentencing Guidelines’ (“Guidelines”) obstruction of justice provision, see U.S.S.G. § 3C1.1, and the Armed Career Criminal Act (“ACCA”), see 18 U.S.C. § 924(e). We have jurisdiction, 28 U.S.C. § 1291, and affirm.
I.
With respect to the felon-in-possession charges, the government had the burden of proving: (1) Defendant knowingly possessed the sawed-off shotgun (count I) and 30.06 rifle (count III); (2) Defendant had been convicted of a felony offense before he possessed the shotgun and rifle; and (3) Defendant’s possession of the shotgun and rifle was in or affecting interstate commerce.

United
*1212
States v. Griffin,
At trial, Defendant admitted he was a convicted felon,
see Old Chief v. United States,
The government presented the testimony of several witnesses in its case-in-chief to prove Defendant knowingly possessed the sawed-off shotgun and 30.06 rifle. With respect to the sawed-off shotgun, two sheriffs deputies testified they discovered the shotgun in Defendant’s vehicle after a traffic stop. The deputies found the shotgun within Defendant’s reach underneath the vehicle’s front seat. The passenger in the vehicle at the time of the stop, Carlos Najar, testified the shotgun did not belong to him. With respect to the 30.06 rifle, Defendant’s former neighbor, adopted daughter, now ex-wife (Mary Serrano), and two former brothers-in-law all testified Defendant possessed the rifle.
After the government rested, Defendant offered the jury an alternative theory. Defendant, in his opening statement, informed the jury that Michael Serrano (Defendant’s son) and Manuel Franco (Najar’s roommate) would testify the sawed-off shotgun belonged to Najar. The evidence would also show, according to Defendant, Mrs. Serrano placed her 30.06 rifle in their house and then called the authorities to report Defendant’s illegal possession of the rifle. Defendant, consistent with his theory of the case, called Michael Serrano as his second witness. Shortly after Michael Serrano took the stand, however, the government requested a bench conference. The government’s attorney told the district judge that he thought Michael Serrano “should be advised of his constitutional rights ... and the reason for that is because [the government] has interviewed him. He has admitted that he was in the possession together with Carlos Najar of a sawed-off shotgun, and if he’s going to testify under oath, he’s going to admit to it.” 1
*1213 The court, outside the presence of the jury, questioned Michael Serrano and learned he had not discussed his constitutional rights, especially his right against self incrimination, with a lawyer. The colloquy between the district court and Michael Serrano proceeded as follows:
THE COURT: ... Mr. Serrano, how old are you?
THE WITNESS: I’m 23.
THE COURT: All right. You may be asked a number of questions here by one of the attorneys that may require you to give testimony about things that you know concerning the shotgun. The government has indicated to me that you have given a statement concerning the sawed-off shotgun. You may be asked questions about matters concerning yourself and that shotgun. And before I permit any questioning about the shotgun and any involvement you may have had with that weapon, if any — I don’t know, I don’t know what the statements are at this point because the questions have not yet been asked — I need -to ask you if you have talked to a lawyer about any of your constitutional rights, specifically the right against self-incrimination?
THE WITNESS: No, ma'am.
THE COURT: All right. I must advise you that a person such as yourself who is now a witness having been sworn to give testimony in this case, you as a witness ha[ve] the privilege under the 5th Amendment to the United States Constitution to decline to respond to a question if that answer would tend to incriminate you. That is, if that answer would tend to indicate that you were guilty of a crime or would furnish a link in the chain of evidence that would be needed to prosecute you for a crime.
I don’t know specifically what information you have and what answers you would give or statements that you would make in response to questions that may be asked of you during the course of your testimony here. However, based upon the representations made by the lawyer for the government here, there may be matters that you would be questioned about that would invoke consideration of the 5th Amendment right. And so when I say that, I ask again whether you have talked to a lawyer about any of these matters?
THE WITNESS: No, ma'am.
THE COURT: Okay. Do you wish to confer with a lawyer about this before you give any further testimony?
THE WITNESS: No, ma'am.
■THE COURT: Can you explain .to me why? Without going into details about the statement or anything about the gun, just tell me why you feel it is not necessary to talk to a lawyer.
THE WITNESS: Because I’m just telling the truth about everything.
THE COURT: I understand that. Has anyone advised you or talked to you about the consequences, the legal consequences that could occur if you give or make certain statements about the gun, the shotgun, and about your involvement with the shotgun?
THE WITNESS: No, ma'am.
THE COURT: All right. I’m going to — -I’m not in a position to determine at this moment that this witness understands the nature of the 5th Amendment privilege. I think he needs counsel, and *1214 I’m not going to permit any further questioning until he has had an opportunity to confer with counsel....
The court then appointed an attorney to confer with the witness and recessed. Michael Serrano exercised his Fifth Amendment privilege against self incrimination after he conferred with his attorney.
Next, Defendant’s attorney informed the. district court he anticipated calling Najar’s roommate, Manuel Franco, to testify. Franco, according to Defendant’s proffer, would testify Najar owned the sawed-off shotgun and, on the night in question, armed himself with the shotgun before he got into Defendant’s vehicle. Franco’s testimony, however, raised the same Fifth Amendment concerns as Michael Serrano’s proffered testimony (i.e., he ran the risk of being charged with misprision of felony or possession of an unregistered illegal firearm if he testified). The district judge similarly appointed counsel to advise Franco of his constitutional rights. Franco exercised his Fifth Amendment privilege after he conferred with his attorney.
The district court found Michael Serrano and Manuel Franco properly invoked their Fifth Amendment privilege because the testimony of both witnesses could furnish a link in the chain of evidence needed to prosecute them or subject them to the possibility of prosecution.
See Hoffman v. United States,
Defendant subsequently testified in his own defense. He testified on direct examination that he had not owned or possessed any firearms, but admitted on cross examination that he had a felon in possession of a firearm conviction. Defendant opined that Najar put the shotgun in his vehicle. Defendant also testified the deputies did not discover the sawed-off shotgun underneath his vehicle’s seat. With respect to the 30.06 rifle, Defendant claimed Mrs. Serrano purchased the rifle and, unbeknownst to him, placed it in their house. The jury convicted Defendant on all counts.
II.
On appeal, Defendant first argues the coercive and intimidating conduct of the district judge and prosecutor caused Michael Serrano and Manuel Franco to invoke the privilege against self incrimination in violation of his constitutional right to present a defense. We review Defendant’s claim that the government violated his constitutional light to present a defense de novo.
United States v. Solomon,
A.
A criminal defendant’s right to present a defense is essential to a fair trial.
United States v. Valenzuela-Bernal,
A defendant’s right to present a defense, however, is not absolute.
Valenzuela-Bernal,
That said, the government cannot substantially interfere with a defense witness’s decision to testify. In
Webb v. Texas,
The due process analysis
Webb
dictates must be conducted on a case-by-case basis.
Smith,
B.
In this case, the government’s actions did not substantially interfere with Defendant’s right to present a defense under the Fifth and Sixth Amendments. The district court found Michael Serrano and Manuel Franco properly invoked their Fifth Amendment privilege. The record supports the court’s finding and Defendant does not challenge it on appeal. Thus, Defendant did not have the constitutional right to compel Michael Serrano or Manuel Franco to waive their Fifth Amendment privileges. Defendant’s right to compel and offer testimony had to bow to accommodate other legitimate interests in the criminal trial process.
Likewise, the joint action of the district judge and prosecutor did not substantially interfere with Defendant’s right to present a defense in violation of the Due Process Clause. The prosecutor did not act in bad faith when he notified the court that the witnesses’ testimony could subject them to prosecution for misprision of felony or possession of an unregistered illegal firearm.
See supra
n. 1. Moreover, the district court’s colloquy with Michael Serrano was different in degree
and
kind from the unconstitutional admonitions in
Webb
and its progeny. The district judge did not threaten the witnesses nor did she employ coercive language. To the contrary, the district judge properly expressed a legitimate concern that the witnesses’ truthful testimony could subject them to prosecution.
See Smith,
Thus, neither the prosecutor nor the district judge discouraged the witnesses from testifying through threats of prosecution, intimidation, or coercive badgering. Indeed, nothing in the record indicates the prosecutor ever spoke a word to Michael Serrano or Manuel Franco about the witnesses’ testimony at trial. The district court engaged in a brief colloquy with Serrano and Franco to determine if the witnesses understood their constitutional rights. The court thereafter appointed counsel to inform the witnesses of their constitutional rights. The witnesses invoked their Fifth Amendment privilege only after conferring with their independent attorneys. The witnesses’ decision not to testify was not the product of improper governmental coercion of the kind the Court condemned in Webb, but instead was a decision insulated from such governmental pressures by the independent and neutral advice of counsel. The governmental action in this case, therefore, did not run afoul of the Due Process Clause.
III.
Second, Defendant argues the district court erred when it denied his motion under 18 U.S.C. § 6003 to grant use immu
*1217
nity to Michael Serrano and Manuel Franco in the “interests of justice.” We review Defendant’s claim that § 6003 permits a district court to grant immunity — an issue of statutory construction' — de novo.
United States v. LaHue,
A.
The Constitution charges the Executive Branch with faithfully executing the laws. U.S. Const. art. II, § 3. To that end, the “Attorney General and United States Attorneys retain broad discretion to enforce the Nation’s criminal laws.”
United States v. Armstrong,
The Immunity Act provides the district court with authority to issue “an order requiring [an individual who has been or may be called to testify] to give testimony or provide other information which he refuses to give or provide on the basis of his privilege against self-incrimination[J”
Id.
§ 6003(a). The district court can
only
enter an order under the Immunity Act when a United States attorney, with proper approval of the Attorney General, requests such an order.
Id.
§ 6003(a)-(b). Thus, “ ‘Congress gave certain officials in the Department of Justice
exclusive authority
to grant immunities.’ ”
United States v. Doe,
Because Congress expressly left the decision to seek immunity “exclusively to the Justice Department!,]”
Doe,
B.
In this case, the district court correctly denied Defendant’s motion to grant Michael Serrano and Manuel Franco immunity. Section 6003 only permits a district court to enter an immunity order upon the request of a United States attorney and the United States attorney made no such request here. The district court did not have the inherent authority to grant Serrano and Franco immunity in the “interests of justice.” Defendant’s reliance upon the Third Circuit’s case in
Smith,
Defendant also argues, relying on the United States Attorney’s Manual, that the prosecutor in this case should have granted Serrano and Franco immunity. Defendant’s argument fails because the manual does not create any substantive rights and, in any event, the decision to grant immunity lies in the
exclusive
discretion of the prosecutor. Moreover, we presume the United States attorney’s office has properly discharged its official duties absent clear evidence to the contrary.
Armstrong,
IV.
Third, Defendant argues the district court violated his right to a jury trial under the Sixth Amendment when it adjusted his base offense level upward two levels for obstruction of justice.
See
U.S.S.G. § 3C1.1;
Blakely v. Washington,
— U.S. —,
A.
In
Booker,
If forfeited, both types of
Booker
error are reviewed under the plain-error test.
Gonzalez-Huerta,
B.
In this case, we review Defendant’s forfeited Booker error for plain error. The Booker error is clear or obvious error under current law. Defendant, however, has failed to carry his burden of demonstrating a reasonable probability exists that, but for the Booker error, the result of his sentencing proceeding would have been different.. To start, Defendant’s base offense level was twenty. See U.S.S.G. § 2K2.1(a)(4)(B). The district court then adjusted Defendant’s offense level upward two levels to twenty-two based upon his obstruction of justice. Id. § 3C1.1.
In addition to that calculation, however, the district court also determined that Defendant was an armed career criminal under 18 U.S.C. § 924(e)(1). Based upon Defendant’s armed career criminal status, the district court determined Defendant’s base offense level was thirty-four. See U.S.S.G. § 4B1.4. Section 4B1.4(b) further required the district court to calculate Defendant’s sentencing range using the greater of the two offense levels—thirty-four for being an armed career criminal or twenty-two for unlawfully possessing a firearm and obstructing justice. The district court, therefore, used the offense level dictated by Defendant’s armed career criminal status (thirty-four) to calculate the applicable Guidelines range. Consequently, the obstruction-of-justice enhancement that Defendant now challenges actually fell out of the offense level calcula *1220 tion. For these reasons, Defendant has failed to show a reasonable probability that the district court’s two level enhancement of his offense level for obstruction of justice affected the length of his sentence. As a result, Defendant has failed to carry his burden under the third prong of the plain-error test and we need not reach the fourth prong.
V.
Finally, Defendant argues the district court violated his Sixth Amendment right to a jury trial under the Sixth Amendment, as construed in
Blakely
and
Booker,
when it enhanced his sentence under the ACCA. Because Defendant did not raise this
Booker
argument in the district court, we review for plain error.
Gonzalez-Huerta,
A.
The ACCA requires a mandatory minimum sentence of fifteen years for a defendant who is (1) convicted of being a felon in possession of a firearm, and (2) has “three previous convictions by any court ... for a violent felony ... committed on occasions different from one another[.]” 18 U.S.C. § 924(e)(1);
Shepard v. United States,
— U.S. —, —,
B.
The ACCA applied to Defendant because (1) a jury convicted him of being a felon in possession of a firearm, and (2) he had, among others, three different felony arson convictions. The ACCA specifically defines arson as a “violent felony.” Defendant does not argue that arson, as defined under New Mexico law, is not a “violent felony” under the ACCA or that the district court considered improper evidence in determining whether his three prior arson felonies constituted “violent felonies” for purposes of § 924(e).
See Shepard,
AFFIRMED.
Notes
. Defendant asserts on appeal that "[t]he prosecutor was disingenuous in raising the self-incrimination issue” and only raised the issue "to gain a tactical advantage at trial[.]” To the extent Defendant is arguing the government engaged in bad faith, we reject his argument because it is not supported by the record.
See United States v. Crawford,
. In
Hunter,
. The district court sentenced Defendant pre-
Blakely
and
Booker.
Defendant argues we should review his claims of Sixth Amendment error de novo because of the intervening change in the law. In
