Appellant Robert Chesney was convicted following a jury trial of knowing conversion of public funds, in violation of 18 U.S.C. § 641, filing false claims, in violation of 18 U.S.C. § 287, and money laundering, in violation of 18 U.S.C. § 1956. We affirm.
I
Chesney’s convictions stem from an elaborate scheme to defraud the Social Security Administration. Special Agent Joseph Malfero of the Department of Health and Human Services’ Inspector General’s Office testified at trial that on June 3, 1991, Randy Illgenfritz, a Social Security Administration Quality Assurance Supervisor, informed him that he had arranged a meeting with Randy Carter, a Social Security Supplemental Income recipient suspected of fraud. At the meeting, Special Agent Malfero recognized Carter as a man that he had seen with a number of different California identification cards and whose true identity he had determined to be Chesney.
After leaving the meeting, a surveillance team began following Chesney. The surveillance team observed him enter several post offices and access a number of different ATM’s (Automatic Teller Machines). On June 10, 1991, agents searched Chesney’s home pursuant to a search warrant. The agents seized social security cards and applications, California identification cards, checks, bank statements, and ATM cards. The government agents then took Chesney into custody.
Chesney was indicted on twenty counts of conversion of public moneys, filing false claims, and money laundering. A jury returned a guilty verdict on all counts and he was sentenced to 24 months in prison.
Chesney argues on appeal that the indictment charging him with violating 18 U.S.C. § 641 was defective, that he was entitled to an instruction on the necessity defense, and that prosecutors failed to prove every element of an 18 U.S.C. § 1956 violation. Ches-ney also contends the district court erred in admitting into evidence exhibits which he claims were prejudicial, cumulative and irrelevant. We address each of his claims in turn.
II
At the end of the government’s case, Ches-ney moved to strike nine counts charging him with knowing conversion of public funds in violation of 18 U.S.C. § 641
1
for failure to state an offense against the United States. The indictment charged, in relevant part,
*643
that “defendant Robert Chesney knowingly converted to his own use money belonging to the United States.... ” Chesney argues the charge failed to express and therefore failed to inform him of the specific intent element of the crime. We review the sufficiency of an indictment
de novo. United States v. Tuohey,
Chesney relies on
Morissette v. United States,
An indictment’s failure to state an element of the charged offense is a fundamental defect that may be challenged at any stage of a criminal proceeding.

United States v. Fogel,
Ill
Chesney also maintains that the district court erred by refusing to give a necessity defense instruction. A defendant is entitled to a necessity defense instruction if he makes a
prima facie
case that meets the legal requirements of necessity.
See United States v. Jennell,
IV
We now turn to Chesney’s contention that the district court erred by denying his Rule 29 motion for judgment of acquittal on the two counts of money laundering. Ches-ney maintains that the government failed to prove that he intended to conceal the ownership and the location of the proceeds. We review a district court’s denial of a motion for acquittal in the same manner as a challenge to the sufficiency of the evidence.
United States v. Shirley,
884 F,2d 1130, 1134 (9th Cir.1989). Thus, we review the evidence presented against Chesney in the light most favorable to the government to determine whether
“any
rational trier of fact could have found the essential elements of the crime beyond a reasonable doubt.”
Id.
(quoting
Jackson v. Virginia,
To prove money laundering in violation of 18 U.S.C. § 1956, the government had to show that (1) Chesney conducted a financial transaction involving property that represented the proceeds of the unlawful conversion of public moneys; (2) he knew that the property represented the proceeds of unlawful conversion of social security benefits; and (3) defendant knew the transaction was designed in whole or in part to conceal or disguise the nature, location, source, control, or ownership of the social security benefits. 18 U.S.C. § 1956(a)(1). Chesney maintains that the government failed to prove that he intended to conceal or disguise the location or ownership of the social security funds he stole from the government. We are unpersuaded.
Two government witnesses testified that the Social Security Administration monitors a recipient’s financial status. In particular, one witness testified that at the time benefit applications are received, the representative requests a copy of the applicant’s bank statement. In other words, a jury could reasonably find that the accounts into which the social security benefits were directly deposited were subject to monitoring by the Social Security Administration. Through the testimony of various government witnesses, the government introduced into evidence a number of exhibits showing that Chesney first deposited the Social Security checks into accounts under his name and an alias and then redeposited social security funds into other accounts under different names. Sometimes Social Security funds were removed from these accounts by Ches-ney and used to open thrift accounts at totally different institutions, under different names. On this record, a rational jury could find beyond a reasonable doubt that Chesney intended to conceal the ownership and location of the proceeds and was engaged in money laundering in violation of 18 U.S.C. § 1956.
V
We now turn to Chesney’s final argument that the district court abused its discretion by admitting into evidence government exhibits that he claims were irrelevant and cumulative as well as confusing and prejudicial. The government exhibits to which Chesney objected were large photographs of Social Security cards, photo identification cards and other forms of identification seized in Chesney’s apartment during his arrest. Because Chesney fails to make any showing that the exhibits’ probative value was substantially outweighed by any prejudice to him, the district court did not abuse its discretion in striking the balance under Rule *645 403 of the Federal Rules of Evidence in favor of admitting the exhibits.
The convictions are AFFIRMED.
Notes
. Section 641 provides, in relevant part:
Whoever embezzles, steals, purloins, or knowingly converts to his use or the use of another, or without authority, sells, conveys or disposes of any record, voucher, money, or thing of value of the United States or of any department or agency thereof ...
Shall be fined not more than $10,000 or imprisoned not more than ten years, or both....
. Although in Aguilar we reviewed the district court’s decision in limine to exclude evidence to support the defendant's necessity defense, the same prima facie showing is necessary to support a district court's grant of a necessity defense instruction.
