PATRICK E. HIGGINBOTHAM, Circuit Judge:

Appellant Andrew A. Martin was convicted of unlawfully conspiring to defraud the United States by impairing the ability of the IRS to ascertain and collect income taxes in violation of 18 U.S.C. § 371, as well as several counts of false statements and tax evasion offenses in violation of 26 U.S.C. §§ 7201 and 7206(1). Martin raises three issues on appeal: the failure of the district court to hold evidentiary hearings on his motions for a Kastigar and a Franks hearing, and the jury instruction with regard to the violation of 18 U.S.C. § 371. We affirm the convictions.

I.

Martin was a businessman who owned several businesses in the offshore oil servicing industry. Gregory Duvieilh, an accountant, was a business associate. Duvieilh started several businesses, including Iron Man Fisheries, Inc., which he incorporated in February 1991 with Martin for the purpose of importing lobsters. Duvieilh owned all of the stock in the company and held sole signature authority on its corporate checking account at the Community Bank of Lafourche in Raceland, Louisiana. Iron Man, however, never did any business and existed only on paper.

In 1990, the IRS assessed the sum of $188,450 as being the "trust fund" portion of the taxes withheld from the wages of employees of Martin's businesses. Martin was personally liable to the IRS for this amount. In an attempt to help Martin frustrate the IRS's efforts to collect the taxes, Duvieilh arranged for Martin to use the Iron Man bank account under the cover of Duvieilh's name. Duvieilh gave Martin signed blank checks to use at Martin's discretion and also signed sales and mortgage documents for Martin's benefit. Duvieilh never filed any corporate income tax returns for Iron Man.

Martin diverted over $500,000 in income into the Iron Man account from various sources. Martin purchased property and assets under the Iron Man name for his personal use, including a houseboat, fishing boats, and personal residences in Baton Rouge and Kenner.

In June 1995, Martin, assisted by Duvieilh, filed an IRS Form 656, Offer and Compromise, stating that he could borrow $20,000 to pay the IRS if it would forgive the remaining liability owed to the IRS. Martin falsely stated therein that he had no income other than his state government salary, received as Executive Assistant to then-Governor Edwin Edwards, and had no assets other than an over-mortgaged house in Galiano, Louisiana. Martin did not list any of his assets sheltered under Iron Man.

Although the $188,000 which the IRS had initially assessed Martin in connection with the withheld wages came from Martin's business operations, Martin also sought to avoid paying taxes on income which he received for the tax years 1994 through 1997. Much of Martin's income during 1996 and 1997 came from cash kickbacks paid by Robert Guidry for Martin's assistance, along with that of Governor Edwards and his son Steven, in securing a hearing before the state police which eventually led to Guidry's obtaining a gambling license for the Treasure Chest Casino. Martin failed to file income tax returns on taxable income amounting to $150,400 in 1994, $138,000 in 1995, and $239,000 in 1997. Martin did file an income tax return in 1996 in which he falsely reported his income to be $76,000 when in fact it amounted to approximately $477,000. Martin failed to pay taxes amounting to $437,671.

As part of its investigation of Martin's taxes, the government received a copy of the transcript of Martin's testimony before a Louisiana grand jury. Martin testified before the state grand jury investigating Governor Edwards as a subpoenaed nontarget witness. During his testimony before the grand jury, Martin testified about high-stakes poker games at the Governor's mansion, and identified some of the players. Several of these named players testified at Martin's tax trial concerning Martin's unreported poker winnings.

The government also obtained wiretap authorizations for the telephones of Cecil Brown during its investigation of Governor Edwards. These taps yielded evidence which the government used to obtain additional wiretaps, which in turn yielded evidence which the government proffered at Martin's tax trial.

Martin filed three major pre-trial motions, two of which are at issue on appeal. The first was a motion to dismiss the indictment under Kastigar due to the government's use of Martin's allegedly immunized state grand jury testimony. The second was a motion to suppress all evidence obtained through wire and electronic surveillance during the government's investigation of Governor Edwards, accompanied by a six volume offer of proof and a motion for a Franks hearing. The district court heard oral argument on the motions and denied them without an evidentiary hearing.

The charges against Martin were tried to a jury which returned a guilty verdict on all counts. Martin moved for a new trial or judgment of acquittal, arguing, inter alia, that the government's evidence at trial highlighted the need for a Kastigar hearing. The district court denied his motion. Martin timely appealed.

II.

Martin argues that his testimony as a non-target witness before the Louisiana grand jury was immunized under Louisiana Code of Criminal Procedure Article 433.A(2). Pursuant to Kastigar v. United States, Martin asserts that the district court should have required the government to show an independent source for its evidence of unreported poker winnings.

Whether Martin had automatic immunity under the Louisiana statute as a nontarget witnesses testifying before a state grand jury is a question of law we review de novo. Factual findings relating to the Kastigar inquiry are reviewed for clear error.

This issue turns on the interpretation of Article 433, which is titled "Persons present during grand jury sessions." Subparagraph A(2) reads in full:

An attorney for a target of the grand jury's investigation may be present during the testimony of said target. The attorney shall be prohibited from objecting, addressing or arguing before the grand jury; however he may consult with his client at anytime. The court shall remove such attorney for violation of these conditions. If a witness becomes a target because of his testimony, the legal advisor to the grand jury shall inform him of his right to counsel and cease questioning until such witness has obtained counsel or voluntarily and intelligently waived his right to counsel. Any evidence or testimony obtained under the provisions of this Subparagraph from a witness who later becomes a target shall not be admissible in a proceeding against him.

It is the last sentence that Martin contends grants him automatic use and derivative use immunity for his testimony as a non-target witness before the grand jury. Under Murphy v. Waterfront Commission and Kastigar federal prosecutors are prohibited from using immunized state testimony in a federal criminal prosecution.

At the outset, it should be noted that Martin is not arguing that he was granted immunity by the district attorney in order to compel his testimony over an assertion of his Fifth Amendment rights. Martin did not assert his Fifth Amendment rights and the district attorney explicitly notified Martin that he was not being granted any immunity at the start of his grand jury testimony. However, immediately following this notice, Martin made certain that he was not a target of the grand jury. Martin argues that as a non-target witness he did not need to assert his Fifth Amendment rights or be granted immunity by the district attorney, since Article 433.A(2) automatically immunized his testimony. He also asserts that his testimony was compelled because the district attorney told him that he had to answer the questions and his appearance was pursuant to a subpoena. The government responds that Martin has acknowledged that he was not granted immunity, that Article 433.A(2) does not automatically confer immunity, and therefore Kastigar does not apply. We agree.

The district court in this case explicitly relied on the reasoning of the District Court for the Middle District of Louisiana in a related case, United States v. Edwards, in which Martin raised exactly the same argument. Although we reach the same conclusion as that court, we do not entirely agree with its reasoning.

Relying on two Louisiana cases, that court concluded that only one Louisiana statute confers statutory immunity, namely Louisiana Code Criminal Procedure Article 439.1. The court relied on a statement from a Louisiana Court of Appeals that "the only Louisiana statute specifically granting any type of immunity (use immunity) is Code of Criminal Procedure Article 439.1, which requires the agreement of the district attorney or the attorney general." Reliance on this quotation is misplaced. Read in context, it is only a restatement of the state's argument in the case, not a statement of Louisiana law by the court. The government also erroneously relies on this language in its argument here.

The district court in Edwards also relied on State v. Tanner, in which the Louisiana Supreme Court ruled that a target of a grand jury investigation who waived his right to remain silent could not use grand jury secrecy laws, including Article 433, to prevent the use of his grand jury testimony at trial. The Edwards court concluded that the state court's pronouncement that the defendant did not receive any immunity was dispositive of Martin's argument. However, Article 433 clearly distinguishes between target and non-target witnesses, and thus the Tanner decision does not control, since unlike Tanner, Martin was not a target witness.

In addition to these cases, the government also cites State v. Poland, contending that the Louisiana Supreme Court has made it clear that Article 433 only relates to who may be present during grand jury proceedings, not immunity. However, as in Tanner, Poland concerned a witness who was a target of the grand jury and the court had no reason to apply Article 433.A(2). Thus we are faced with an ambiguous statute and no relevant state case law to guide us in its interpretation.

We begin by examining the language of the statute. On its face, the statute only applies to evidence or testimony "obtained under the provisions of this Subparagraph" from a non-target witness "who later becomes a target." The parties dispute what it means to "later become a target." Martin argues for a broad interpretation, such that a witness who becomes a target of a criminal investigation at any later time cannot have his testimony as a non-target witness used against him. The government responds by arguing that "later becomes a target" applies only to those witnesses who become a target of the grand jury before which they are testifying. The government has the better interpretation of the statute.

The interpretation of "later becomes a target" is clarified by the limitation on what evidence and testimony may not be used pursuant to Article 433.A(2). Only testimony and evidence "obtained under the provisions of this Subparagraph" are covered by the provision. The provisions Subparagraph A(2) concern only two types of witnesses: target witnesses and nontarget witnesses who become a target because of their testimony while testifying. The provisions of the Subparagraph do not relate to non-target witnesses who become the target of a criminal investigation only after they have testified. Therefore, the only type of witness that testifies under the provisions of the Subparagraph and later becomes a target is one that becomes a target while testifying. Thus, Article 433.A(2) only applies to the evidence or testimony from a non-target witness who becomes a target because of his testimony while testifying before the state grand jury. This interpretation of the statute was also adopted by the district court.

Martin argues that this interpretation of the statute is not supported by the legislative history of the bill which added subparagraph A(2) to Article 433. First, Martin notes that the Senate adopted an amendment to the bill which read in relevant part, "Any evidence or testimony obtained in violation of this provision shall be inadmissible at trial on any criminal charges arising out of said grand jury investigation." This amendment was deleted and replaced with the current language, "Any evidence or testimony obtained under the provisions of this Subparagraph from a witness who later becomes a target shall not be admissible in a proceeding against him." Martin argues that the language "arising out of said grand jury investigation" is the same as the interpretation we adopt, and was ultimately rejected by the legislature in favor of protection for nontarget witnesses who become a target at any later time.

Second, Martin notes that the House version of the bill which was sent to the Senate granted the right to have counsel present in the grand jury to all witnesses, not just a target. Martin argues that the final bill was a trade-off, limiting the right to have an attorney present to target witnesses in exchange for immunizing non-target witnesses' testimony. Martin therefore concludes that the legislature provided automatic use and derivative use immunity for all non-target witnesses.

Martin's reading of the legislative history is not unreasonable, but the language of the statute as adopted simply does not support a broad grant of use and derivative use immunity. As discussed above, the language of the statute indicates that only those non-target witnesses who become targets while testifying are covered by Article 433.A(2). This interpretation is not inconsistent with the legislative history. The version of the bill accepted and then rejected by the Senate provided very narrow protection since it required a violation of the provisions of the subparagraph and only prohibited the use of the testimony in criminal trials arising out of the grand jury where the violation occurred. The final version of the statute is broader, requiring only that the witness become a target while testifying and preventing the use of the witness's testimony in any proceeding against the witness. Our interpretation of the statute is not inconsistent with the legislative history because it is not the same as the one rejected by the Senate.

We now turn to the application of the statute to Martin. Article 433.A(2) does not apply to Martin's testimony because, as the district court noted, there is "no evidence to show that Mr. Martin became a target of the East Baton Rouge Parish grand jury before which he was called to testify." Because Martin failed to satisfy his initial burden of demonstrating that he testified under a state grant of immunity, Kastigar does not apply and the district court did not err in refusing to conduct a Kastigar hearing.

III.

Martin next argues that the affidavit that supported the authorization of a wiretap of Cecil Brown's home and office telephone recklessly or deliberately misrepresented the truth and that without these uncorroborated accusations the remaining parts of the affidavit do not support probable cause. Because the wiretap of Cecil Brown's home and office led to evidence used to obtain the wiretaps that yielded the evidence used at trial against Martin, Martin argues that the evidence against him must be excluded. We review the denial of a Franks hearing de novo.

The legality of the Cecil Brown wiretaps have been considered and upheld three times by this court. Martin was an appellant in one of these appeals and was denied a rehearing by this court as well as certiorari by the Supreme Court. Here Martin raises the same issues once again and asks this court to reach a different conclusion when it reviews the issue for the fourth time.

Martin devotes a significant portion of his brief to establishing that he made the requisite "substantial preliminary showing" that a false statement was deliberately or recklessly included in the affidavit that supported the application for the wire tap of Cecil Brown's telephones. However, if the remaining portions of the affidavit support probable cause, Martin was not entitled to a Franks hearing.

Martin's assertions that the activities in the affidavit are legal when considered without the stricken portions are without merit. The remaining portions of the affidavit do not need to prove beyond a reasonable doubt that a crime was being committed, only that considering the "totality of the circumstances", the judge issuing the warrant could reasonably conclude that the warrant was justified. In accordance with Edwards, Cecil Brown and James Brown, we hold that there was probable cause to sustain the issuance of the warrants.

IV.

Martin's final argument is that the district court erred in not including "deceit and dishonest means" in its jury instruction on appellant's 18 U.S.C. § 371 charge. Conspiracies charged under 18 U.S.C. § 371 can have either of two objectives: to violate federal law, or to defraud the United States. Martin argues that conspiracies to defraud require the objective of the conspiracy to be interference with a government function "by deceit, craft or trickery, or at least by means that are dishonest." Martin argues that the jury instruction erred in two respects. First, it was an instruction on an "offense clause" conspiracy, not a "defraud clause" conspiracy as the indictment charged, and thus was a constructive amendment of the indictment. Second, the instruction failed to include any language on deceit or dishonest means. Because many activities that citizens undertake with the goal of making the government's job more difficult are protected by the First Amendment, failure to include the deceit or dishonest means instruction made the charge overbroad. In light of this alleged overbroadness, Martin argues the court should find clear error.

Martin made no objection to the district court concerning the jury instruction, nor did he submit a proposed instruction that covered his First Amendment defense. Therefore, we review the district court's instruction for plain error. "Plain error occurs only when the instruction, considered as a whole, was so clearly erroneous as to result in the likelihood of a grave miscarriage of justice."

Martin's first argument is without merit in light of the entire jury instruction. The jury instruction states that the first element of the offense is that the defendant and at least one other person conspired to "commit the crime of defrauding the United States." This is clearly a "defraud clause" instruction.

As to the second argument, a charge under the "defraud clause" does not require a "deceit and dishonest means" instruction. In United States v. Saks, we upheld a jury instruction which consisted of the statutory language of § 371, which does not contain "deceit and dishonest means" language. In reviewing the jury instruction, we stated that "because defendants' claim of prejudice is based solely on the failure to give adequate explanation of the offense — beyond the reading of the statutory language itself — their burden is especially heavy." Although the jury instruction affirmed in Saks did not include the "deceit and dishonest means" language, the district court did read the indictment which included that language.

Here, the district court included language from the indictment in its instruction, stating that the defendant was charged with "conspiring to frustrate the collection by the [IRS] of trust fund liability taxes due and owing by the Defendant and to disguise and conceal this scheme from the [IRS]." Although not read by the court, the indictment, a copy of which the jury had during deliberations, charged that "[a]mong the objects and purposes of the conspiracy were through the use of deceit, craft, trickery, and dishonest means" to frustrate the collection of taxes due and to disguise and conceal the scheme.

Given that the indictment included the "deceit and dishonest means" language, and that the evidence at trial clearly demonstrated a scheme that at a minimum involved "trickery", the jury instruction cannot be viewed as "so clearly erroneous as to result in the likelihood of a grave miscarriage of justice." Therefore the jury instruction was not plain error.

V.

For the foregoing reasons, the defendant's convictions are hereby AFFIRMED.
