    MELINDA LANGLEY
    Defendant–Appellant
    Appeals from the United States District Court
    for the Eastern District of Louisiana
    Before HIGGINBOTHAM, DENNIS, and PRADO, Circuit Judges.
    EDWARD C. PRADO, Circuit Judge:
    Ernestine Girod, Una Favorite Brown, and Melinda Langley were each
    indicted on one count of conspiracy (18 U.S.C. § 371) and multiple counts of
    Nos. 10-30128, 10-30339
    health care fraud (18 U.S.C. § 1347), and Brown and Girod were charged with
    three counts each of making false statements to law enforcement officers (18
    U.S.C. § 1001), all in relation to fraudulent Medicaid reimbursement claims
    made through A New Beginning of New Orleans (“ANBNO”), a Medicaid Early
    Periodic Screening Diagnosis and Treatment (“EPSDT”) organization that
    provides minor, disabled Medicaid recipients with Personal Care Services
    (“PCS”). A jury convicted the three women on all but three of Langley’s health-
    care fraud counts.     Brown, Girod, and Langley separately appeal their
    convictions and sentences on various grounds. We affirm.
    I. FACTUAL AND PROCEDURAL BACKGROUND
    Brown and Langley worked for ANBNO, a PCS provider co-owned by
    Akasia Lee, a cooperating witness in the case who pleaded guilty to conspiracy.
    Specifically, ANBNO provided PCS to disabled children covered under Medicaid,
    teaching them activities of daily living (“ADL”) like personal hygiene, light food
    preparation, and basic house cleaning. Each child had a specific plan of care
    (“POC”) that detailed the activities the PCS provider could provide and Medicare
    would reimburse. EPSDT PCS services could only be provided in the child’s
    home, and ANBNO employees providing PCS—including Brown and
    Langley—underwent training in proper documentation, rules, regulations, and
    services provided. A binder of all EPSDT rules, regulations, guidelines, time
    sheets, and the POC was placed in the home of each PCS client. Brown and
    Langley claimed to provide PCS services to Medicaid recipients, and Girod had
    three children on Medicaid who purportedly received PCS from ANBNO
    employees.
    From 2001 to 2006, the defendants, among others, engaged in a conspiracy
    to defraud Medicaid by creating false documentation that PCS services were
    provided to Medicaid recipients when the services were not provided. Brown and
    Langley submitted false PCS time sheets and daily care sheets saying they
    2
    Nos. 10-30128, 10-30339
    provided specific PCS services listed in their clients’ POCs, at specific times,
    when these services were not provided. In reality, Brown, Langley, and other
    ANBNO PCS providers failed to attend mandatory trainings, transported PCS
    clients around in their cars, took clients to social settings like the park, and
    babysat them—actions that are all verboten by Medicaid and not Medicaid
    reimbursable. Parents of PCS-eligible children, including Girod, signed off on
    their children’s PCS time sheets in exchange for kickbacks from Lee and other
    ANBNO PCS providers.         In sum, ANBNO defrauded Medicaid out of
    approximately four million dollars.
    On June 5, 2008, a grand jury returned an indictment against Girod,
    Brown, and Langley, among others. A superceding indictment was issued on
    February 12, 2009, charging Girod with conspiracy (Count 1), twenty-five counts
    of health care fraud (Counts 15–39), and three counts of false statements to law
    enforcement officers (Counts 60–62); Brown with conspiracy (Count 1), ten
    counts of health care fraud (Counts 5–14), and three counts of false statements
    to law enforcement officers (Counts 63–65); and Langley with conspiracy (Count
    1) and thirteen counts of health care fraud (Counts 17–59), among other
    defendants.
    Brown filed a motion to dismiss the indictment due to prosecutorial
    misconduct in May 2009. After the magistrate judge conducted a hearing, he
    recommended that the district court deny the motion.        The district court
    conducted two additional days of hearings on Brown’s motion and summarily
    denied it on August 24, 2009. A jury trial was held from September 4, 2009, to
    September 9, 2009. The jury convicted Brown on Counts 1, 5–14, 63, and 65;
    Langley on Counts 1 and 47–56; and Girod on Counts 1, 15–39, and 60–62.
    Girod was sentenced to 24 months’ imprisonment, a special assessment, and
    restitution in the amount of $68,140. Brown was sentenced to 21 months’
    imprisonment, a special assessment, and restitution in the amount of $33,405.
    3
    Nos. 10-30128, 10-30339
    Langley was sentenced to 15 months’ imprisonment, a special assessment, and
    restitution in the amount of $47,717. Each also received a three-year term of
    supervised release.
    The defendants separately timely filed their notices of appeal.
    II. ANALYSIS
    A.    Brown’s Motion To Dismiss the Indictment Due to Prosecutorial
    Misconduct
    The Sixth Amendment guarantees a criminal defendant the right to
    present witnesses to “establish his defense without fear of retaliation against the
    witness by the government.” United States v. Dupre, 
    117 F.3d 810
    , 823 (5th Cir.
    1997). “In addition, the Fifth Amendment protects the defendant from improper
    governmental interference with his defense.” United States v. Bieganowski, 
    313 F.3d 264
    , 291 (5th Cir. 2002) (internal quotation marks and citations omitted).
    Thus, “substantial governmental interference with a defense witness’ choice to
    testify may violate the due process rights of the defendant.” 
    Dupre, 117 F.3d at 823
    (quoting United States v. Whittington, 
    783 F.2d 1210
    , 1219 (5th Cir. 1986)).
    Whether a defendant has made a showing of substantial interference is a fact
    question, and we therefore review a claim of prosecutorial intimidation for clear
    error. United States v. Thompson, 
    130 F.3d 676
    , 686–87 (5th Cir. 1997). Any
    violation is subject to harmless-error analysis, and we “will not reverse unless
    the prosecutor’s conduct was sufficiently egregious in nature and degree so as
    to deprive [the defendant] of a fair trial.” United States v. Skilling, 
    554 F.3d 529
    ,
    567 (5th Cir. 2009) (internal quotation marks and citation omitted) ( substitution
    in Skilling, aff’d in part and vacated on other grounds by Skilling v. United
    States, 
    130 S. Ct. 2896
    (2010).
    Likewise, “as a general rule, ‘[w]itnesses . . . to a crime are the property of
    neither the prosecution nor the defense. Both sides have an equal right, and
    should have an equal opportunity, to interview them.’” United States v. Soape,
    4
    Nos. 10-30128, 10-30339
    
    169 F.3d 257
    , 270 (5th Cir. 1999) (quoting Gregory v. United States, 
    369 F.2d 185
    , 188 (D.C. Cir. 1966)) (second alteration in original). Of course, “[n]o right
    of a defendant is violated when a potential witness freely chooses not to talk [to
    defense counsel].” In re United States, 
    878 F.2d 153
    , 157 (5th Cir. 1989).
    1.     The Government’s Visits to Defense Witnesses Allen and
    Randall
    Brown argues that the Government substantially interfered with her right
    to present witnesses in her favor when agents visited Semaj Allen and Lakita
    Randall—both        identified    as    defense     witnesses     on    Brown’s     pretrial
    disclosures—and questioned them regarding the Medicaid fraud at ANBNO.
    Allen and Randall subsequently declined to testify on Brown’s behalf. They were
    school teachers who worked with Brown at the same school and were PCS
    providers with ANBNO. Brown alleges that Allen and Randall would have
    testified that Brown spent time with the Morales boys—two children Brown
    provided PCS for—before school, at the park, and at football practice.1
    We affirm Brown’s convictions on this ground because the district court did
    not clearly err in deciding that the agents’ conduct did not substantially interfere
    with Allen’s and Randall’s free choice to testify. Both the prosecution and the
    defense have a right to interview witnesses; the fact that Allen and Randall were
    interviewed after the Government found out they were on the defense witness
    list was not improper, even if the Government previously knew Allen and
    Randall were connected with ANBNO. The undisputed testimony was that the
    two agents asked to talk with both witnesses about the ANBNO investigation,
    informed them that they did not have to speak with them, and told them that
    answering questions was voluntary and that they could stop the interview at any
    time. The agents did not tell Allen or Randall that they were targets of the
    1
    None of these facts could have exonerated Brown for Medicaid fraud, as the charges
    against her were for a failure to provide the specific PCS services claimed on her time sheets
    on the dates and times claimed, not a failure to generally spend time with her PCS clients.
    5
    Nos. 10-30128, 10-30339
    Medicaid fraud investigation nor did they tell Allen or Randall that they had
    engaged in wrongdoing or criminal conduct. Nor did the “Martha Stewart”
    warning that Allen’s and Randall’s only obligation was to speak truthfully
    amount to “substantial interference” in their decision to testify.            See
    
    Bieganowski, 313 F.3d at 291
    –92 (holding that prosecutor’s comment that a
    defense witness could be prosecuted for perjury did not amount to substantial
    interference); 
    Thompson, 130 F.3d at 687
    (holding that a warning of the
    consequences of perjury “even if carried out in a caustic manner, is no cause to
    dismiss the indictment against the defendants”) (citation omitted).
    In short, Brown hangs her hat on the correlation between the agents’
    interviews and the witnesses’ subsequent decisions not to testify on Brown’s
    behalf.   But correlation is not enough; Brown must at a minimum prove
    causation. The district court rejected Brown’s causation argument and this
    finding was not clearly erroneous. See 
    Skilling, 554 F.3d at 571
    (rejecting a
    “proof in the pudding” argument that there must have been substantial
    interference where many potential witnesses declined to cooperate with the
    defense); 
    Thompson, 130 F.3d at 687
    (“The defendant bears the burden of
    showing that testimony would have been different but for the government’s
    actions.”). There are a multitude of reasons why Allen and Randall may have
    decided not to testify, neither witness testified to improper conduct on the part
    of the agents, and Allen stated in her affidavit that her decision not to testify
    was not due to intimidation by the prosecution.
    Even if the information Allen and Randall obtained from the interviews
    caused the witnesses to decide not to testify on Brown’s behalf, Brown has
    nevertheless failed to show that the district court committed clear error when
    it found that there was no substantial interference with Allen’s and Randall’s
    free choice to decide for themselves whether they wished to testify. Presenting
    the potential defense witnesses with the facts of the investigation and the crimes
    6
    Nos. 10-30128, 10-30339
    charged does not amount to witness intimidation; there must be evidence of
    threats or intimidation. See United States v. Viera, 
    839 F.2d 1113
    , 1118 (5th Cir.
    1988) (en banc); 
    Bieganowski, 313 F.3d at 291
    –92. Testimony from the special
    hearings on Brown’s motion to dismiss the indictment shows that neither Allen
    nor Randall knew the details of the crimes of which Brown was charged before
    meeting with the agents, that Allen never felt threatened or intimidated by the
    agents and that she subsequently decided she did not want to put her family
    through the stress of trial, and that Randall was generally uncooperative and
    Brown could only speculate as to the reason why Randall decided not to testify
    on Brown’s behalf. The government’s right to interview Allen and Randall did
    not disappear simply because they may have been ignorant of Brown’s crimes.
    If, after learning the true nature of Brown’s alleged crimes, Allen and Randall
    decided not to testify on her behalf for whatever reason, that is their choice.
    2.    The Government’s Phone Call to Prosecution Witness Lee
    Brown also alleges prosecutorial misconduct relating to prosecution
    witness Akasia Lee, a co-owner of ANBNO who pled guilty to Count 1 of the
    indictment and became a cooperating witness for the Government. At the
    evidentiary hearings and in affidavits, the uncontroverted evidence was that Lee
    had a meeting with prosecutors on March 25, 2009, at 10:00 a.m., and that she
    had also scheduled a meeting with the defense for the same date and time. At
    around 10:15 a.m., Lee was sitting in the defense office, and the defense meeting
    had not yet started due to an attorney being late. Agent Delanueville called Lee
    at 10:15 to remind her of her appointment with the prosecution, and told her she
    should honor her meeting. Lee left the defense office and went to meet with the
    prosecution. Thereafter, Lee did not meet with the defense.
    Brown points to evidence that the prosecutor was angry that Lee was
    meeting with the defense, and the prosecutor told Lee it was not in Lee’s best
    interest to meet with defense counsel without her attorney present. During the
    7
    Nos. 10-30128, 10-30339
    evidentiary hearing, Brown’s attorney Avery Pardee testified that she talked
    with Lee’s attorney David Belfield after the March 25 incident, and that he told
    her that he did not want Lee meeting with anyone and that the prosecutor
    wanted to be present for all meetings with Lee. In his affidavit, however,
    Belfield stated that the prosecutor did not demand to be present during defense
    interviews with Lee and that the prosecutor did not “shut down” Lee’s March 25
    meeting with the defense. As Pardee admitted on cross-examination during the
    evidentiary hearing, no witnesses told her that they were told not to cooperate
    with the defense, she had no evidence of threats or retribution, and it had been
    three months since she had tried to schedule a meeting with Lee.
    Accordingly, we hold that the district court did not clearly err when it
    denied Brown’s motion to dismiss the indictment on this ground, and we affirm
    Brown’s convictions.
    B.     Sufficiency of the Evidence Supporting Girod’s Convictions
    We review a district court’s denial of a motion for judgment of acquittal de
    novo. United States v. Myers, 
    104 F.3d 76
    , 78 (5th Cir. 1997).2 The jury’s verdict
    will be affirmed “if a reasonable trier of fact could conclude from the evidence
    that the elements of the offense were established beyond a reasonable doubt.”
    
    Id. In assessing
    the sufficiency of the evidence, we do not evaluate the weight
    of the evidence or the credibility of the witnesses, but view the evidence in the
    light most favorable to the verdict, drawing all reasonable inferences to support
    the verdict. 
    Id. at 78–79.
           1.     Girod’s Ties to the Fraudulent Documents Submitted by Lee
    2
    Contrary to the Government’s assertion, Girod’s counsel clearly moved for acquittal
    of all charges “for failure to prove the case beyond a reasonable doubt,” and in addition,
    specifically challenged Counts 60–62 for listing the incorrect date of Girod’s false statements.
    Girod’s appeal challenging the denial of her motion for a judgment of acquittal is therefore
    subject to de novo review.
    8
    Nos. 10-30128, 10-30339
    Girod challenges her convictions first on the ground that there was no
    evidence connecting her to the fraudulent PCS forms submitted to Medicaid by
    Lee. To prove health care fraud, the Government had to prove that Girod
    “knowingly and willfully” executed a scheme “to defraud any health care benefit
    program.” 18 U.S.C. § 1347(1). To prove conspiracy, the Government had to
    show that she conspired with at least one other person to defraud the United
    States and that one conspirator committed “any act to effect the object of the
    conspiracy.” 18 U.S.C. § 371.
    Specifically, Girod argues there was no evidence she was “directly involved
    or participate[d] in any manner in the conspiracy as there was no proof offered
    that [she] actually authored or signed any of the documents filed with Medicaid.”
    The Government is not required, however, to show that Girod herself submitted
    the forms to Medicaid in order to charge her with Medicaid fraud and conspiracy.
    The indictment charged Girod with creating false time sheets and PCS daily
    schedules for services she claimed to have witnessed for her children, with being
    paid by ANBNO and Lee for “creating fraudulent documentation to support
    billings to Medicaid,” and charged that in general false time sheets were made
    and ANBNO employees were not providing the PCS services claimed. These
    charges were supported at trial with testimony from Connie Smith, who testified
    she split her ANBNO check with Girod (for PCS Smith supposedly provided
    Girod’s child but did not) in exchange for Girod giving her blank, pre-signed time
    sheets. Akasia Lee also testified that Girod filled out false PCS time sheets for
    her children and split the Medicaid payment with Smith for the PCS services
    Smith was claiming for Girod’s child, and that Lee gave Girod checks from her
    own personal account for one-half the payment amount Medicaid would
    reimburse for the services falsely claimed for Girod’s children.
    With respect to Girod’s argument that no one testified to recognizing her
    handwriting on any of the PCS documents submitted to Medicaid, Lee testified
    9
    Nos. 10-30128, 10-30339
    that she recognized Girod’s handwriting on several training sign-in sheets where
    Girod signed as ANBNO-employee Charvel Steward. Likewise, Audra Scott
    testified that Girod signed her name on ANBNO forms. While Lee testified that
    the time sheets were falsified to conform to Medicaid requirements, the jury
    could have reasonably inferred from Lee’s and Smith’s testimony that Girod
    signed the blank PCS forms she gave to Smith.
    In sum, there was substantial evidence from which the jury could have
    concluded that Girod was involved in the conspiracy and that she knowingly and
    willfully participated in the health care fraud at ANBNO.
    2.    Girod’s Specific Intent To Commit Medicaid Fraud
    Girod also argues she lacked the intellectual capacity to form the specific
    intent to commit fraud. Girod points to evidence that she only completed eighth
    grade and had difficulty reading, and that Dr. Michael Chafetz (Ph.D.), a
    neuropsychologist, determined that she had low verbal comprehension, read at
    a fifth-grade level, and had a first- or second-grade level of reading
    comprehension. While Girod may have had a low level of education and was low
    performing, there was sufficient evidence from which a rational jury could have
    determined she had the mental capacity to form the specific intent to commit
    health care fraud.
    On cross-examination, Dr. Chafetz testified that Girod is capable of
    knowing right from wrong, knowing that stealing is wrong, and telling a lie. He
    also testified that Girod has passed a drivers’ test, has raised kids, and can sign
    and cash checks. According to Dr. Chafetz, Girod is capable of making decisions,
    and she tested at the nineteenth percentile (81% do better) for daily living skills,
    which is adequate. Dr. Chafetz further testified that she is also capable of
    fulfilling basic activities of daily living and recognizing when someone else is
    doing that for her children. Multiple other witnesses who know Girod testified
    that they did not know or suspect she had any mental disabilities or problems.
    10
    Nos. 10-30128, 10-30339
    Christie Coleman, the parent of one of Girod’s PCS clients, testified that, in the
    fourteen years she had known Girod, Girod never seemed mentally impaired and
    never had any problems communicating with her. Scott testified that she had
    no knowledge that Girod had any mental or physical problems. Lee testified
    that Girod never showed any difficulty in understanding the material explained
    in the training sessions.
    Multiple witnesses testified that, while Girod was never an ANBNO
    employee, she posed as Steward at training sessions (sign-ins and taking tests),
    picked up Steward’s checks and mail at ANBNO, and signed payroll receipt
    forms in Steward’s name. The jury could have concluded based on Dr. Chafetz’s
    testimony that Girod could understand that it was wrong to pretend to be
    someone else, and that she did it anyways by helping Steward avoid the
    mandatory ANBNO training requirements for providing PCS services. Finally,
    Scott testified that Girod asked her to put Girod’s checks in Scott’s name to avoid
    involving Girod’s social security withholdings. Girod’s purposeful tax fraud is
    further proof Girod had the capacity to commit health care fraud.
    Viewing all the evidence in the light most favorable to the verdict, the jury
    could have reasonably concluded that Girod knew right from wrong, knew PCS
    services were not being provided to her children, and knew she was pre-signing
    blank PCS time sheets for services that were not being provided to her children
    in exchange for money from Lee and Scott.
    3.    Whether the Crimes Affected Commerce
    Girod also argues the Government did not show the health care crimes
    affected commerce. Specifically, she argues that because the acts all involved
    Louisiana businesses and Louisiana residents, interstate commerce was not
    affected. We disagree. There was ample evidence from which the jury could
    11
    Nos. 10-30128, 10-30339
    have concluded that the Louisiana Medicaid program is a joint federal–state
    program in which ANBNO participated.
    To the extent Girod’s challenge is that the jury instruction was vague and
    did not specify how the program must affect commerce, she did not challenge the
    instruction at trial, and we therefore review this challenge for plain error.3 See
    United States v. Klein, 
    543 F.3d 206
    , 212 (5th Cir. 2008). The district court
    instructed the jury that the crimes charged must be against a “health care
    benefit program,” which, inter alia, is a program “affecting commerce.” Even if
    the instruction was erroneously vague, any error did not affect Girod’s conviction
    as there was substantial testimonial evidence explaining ANBNO’s ties to
    Medicaid, which is a federally funded program that indisputably affects
    interstate commerce. See id.; United States v. Hickman, 
    331 F.3d 439
    , 443–44
    (5th Cir. 2003) (finding no plain error where the district court failed to include
    the words “affecting commerce” in the instruction on health care fraud). Nor
    does Girod’s conviction on this count seriously affect the fairness or integrity of
    the judicial proceedings, as she does not contend that Medicaid is not a “health
    care benefit program” under the statute.
    Girod also cites to United States v. Chambers, 
    408 F.3d 237
    (5th Cir. 2005),
    a case that involved a constructive amendment to an indictment on the
    “interstate commerce” element of the crime of a felon in possession of
    ammunition. In Chambers, the indictment articulated a specific theory of how
    the ammunition affected interstate commerce, and the jury convicted on a
    different theory. This Court explained that Chambers’s conviction had to be
    3
    Error is plain only when it is clear or obvious and it affects the defendant’s substantial
    rights. A defendant’s substantial rights are only affected if the error “affected the outcome of
    the district court proceedings.” United States v. Olano, 
    507 U.S. 725
    , 734 (1993). If these
    conditions are met, then we will only reverse the error if it seriously affects the “fairness,
    integrity, or public reputation of judicial proceedings.” United States v. Cotton, 
    535 U.S. 625
    ,
    631–32 (2002) (citation omitted).
    12
    Nos. 10-30128, 10-30339
    overturned because to allow a conviction based on the second theory “would
    allow that element to be established on the basis of a set of fact wholly different,
    separate and distinct from the one set of facts particularly alleged in the
    indictment relevant to that element, and would thus constitute an impermissible
    constructive amendment of the indictment.” 
    Id. at 247.
    Here, there is no
    dispute that the “affecting commerce” element of health care fraud has always
    been that the fraud was to Medicaid, a federally funded program that affects
    commerce.
    4.     The Date Alleged in the Indictment
    Girod also moved for acquittal below based on the failure of the
    government to prove the date charged in the indictment beyond a reasonable
    doubt. The indictment charged her with making false statements “on or about
    August 26, 2006,” but the testimony from trial showed that the false statements
    were made on April 26, 2006.         Girod argues this four-month discrepancy
    constitutes a material variance from or constructive amendment of the
    indictment under Chambers. We disagree.
    “A constructive amendment occurs when the government changes its
    theory during trial so as to urge the jury to convict on a basis broader than that
    charged in the indictment, or when the government is allowed to prove ‘an
    essential element of the crime on an alternative basis permitted by the statute
    but not charged in the indictment.’” United States v. Robles–Vertiz, 
    155 F.3d 725
    ,
    728 (5th Cir. 1998) (quoting United States v. Salvatore, 
    110 F.3d 1131
    , 1145 (5th
    Cir. 1997)). In this Circuit, “an allegation as to the time of the offense is not an
    essential element of the offense charged in the indictment and, ‘within
    reasonable limits, proof of any date before the return of the indictment and
    within the statute of limitations is sufficient.’” Russell v. United States, 
    429 F.2d 237
    , 238 (5th Cir. 1970) (per curiam) (citation omitted); see United States v.
    Tunnell, 
    667 F.2d 1182
    , 1186 (5th Cir. 1982) (“In this circuit, it is established
    13
    Nos. 10-30128, 10-30339
    that the prosecution is ‘not required to prove the exact date; it suffices if a date
    reasonably near is established.’”) (quoting United States v. Grapp, 
    653 F.2d 189
    ,
    195 (5th Cir. 1981)); see also United States v. Valdez, 
    453 F.3d 252
    , 259–60 (5th
    Cir. 2006) (same). The discrepancy between the indictment and the evidence at
    trial therefore is not a constructive amendment, as the date is not an essential
    element that was proved on an alternate basis and the Government’s theory of
    guilt at trial did not change.
    A variance occurs “when the proof at trial depicts a scenario that differs
    materially from the scenario charged in the indictment but does not modify an
    essential element of the charged offense.” United States v. Delgado, 
    401 F.3d 290
    , 295 (5th Cir. 2005).        We determine whether a variance occurred by
    comparing the evidence presented at trial with the language of the indictment.
    See United States v. Medina, 
    161 F.3d 867
    , 872 (5th Cir. 1998). If a variance did
    occur, we reverse only if the variance prejudiced the defendant’s substantial
    rights. See 
    Delgado, 401 F.3d at 295
    ; 
    Medina, 161 F.3d at 872
    . In determining
    whether a variance resulted in prejudice, we employ a harmless-error analysis.
    United States v. Ramirez, 
    145 F.3d 345
    , 351 (5th Cir. 1998); United States v.
    Dean, 
    59 F.3d 1479
    , 1491 (5th Cir. 1995).
    The discrepancy in dates is not a material variance. “A five-month
    variance between the date alleged and the date proved is not unreasonable as
    a matter of law as long as the date proven falls within the statute of limitations
    and before the return of the indictment.” United States v. Wilson, 
    116 F.3d 1066
    ,
    1089 (5th Cir. 1997) (citation omitted), vacated on other grounds by United
    States v. Brown, 
    161 F.3d 256
    (5th Cir. 1998) (en banc); see Russell v. United
    States, 
    429 F.2d 237
    , 238 (5th Cir. 1970) (“[W]ithin reasonable limits, proof of
    any date before the return of the indictment and within the statute of limitations
    is sufficient.”). Because the April 26, 2006 date is only four months apart from
    the date charged in the indictment and there is no dispute that it falls within the
    14
    Nos. 10-30128, 10-30339
    statute of limitations, Girod’s argument that this variance warrants overturning
    her convictions fails.
    Moreover, a variance between allegations and proof is fatal “only when it
    affects the substantial rights of the defendant by failing to sufficiently notify him
    so that he can prepare his defense and will not be surprised at trial.” 
    Phillips, 664 F.2d at 1036
    . The Government used the “on or about” designation in the
    indictment, explained the context in which the false statements were made, and
    explained the specific statements that were false and made to federal
    investigators. Girod’s false statements charged in the indictment were: (1) “that
    an employee from ANBNO was present in her house for two hours per day with
    each child for a total of 6 hours per day”; (2) “that ANBNO employees came to
    her house every day for 6 hours per day, 7 days per week during the entire time
    her children were enrolled with ANBNO”; and (3) “that AKASIA LEE did not
    pay her $72 per week every two weeks, or pay her any amount, for billing
    Medicaid services rendered to GIROD’s children.” This was sufficiently specific
    to put Girod on notice of which statements the Government intended to prove
    were false. Indeed, Girod has not demonstrated that she was surprised or
    prejudiced in any way by the August 26, 2006 date in the indictment.
    In sum, we affirm Girod’s convictions on all grounds.
    C.    Girod’s Sentencing Enhancements
    Because Girod did not object to her sentence on the grounds of an incorrect
    sentencing enhancement before the district court, our review is for plain error.
    United States v. Jasso, 
    587 F.3d 706
    , 709 (5th Cir. 2009). Plain error exists
    when: “(1) there was an error; (2) the error was clear and obvious; and (3) the
    error affected the defendant’s substantial rights.” 
    Id. (quoting United
    States v.
    Villegas, 
    404 F.3d 355
    , 358–59 (5th Cir. 2005)) (internal quotation marks
    omitted). “If all three conditions are met an appellate court may then exercise
    its discretion to notice a forfeited error but only if (4) the error seriously affects
    15
    Nos. 10-30128, 10-30339
    the fairness, integrity, or public reputation of judicial proceedings.” 
    Id. at 709
    n.4 (quoting United States v. Ellis, 
    564 F.3d 370
    , 377 (5th Cir. 2009)) (internal
    quotation marks omitted). This Court reviews a district court’s interpretation
    and application of the guidelines de novo. United States v. Cisneros–Gutierrez,
    
    517 F.3d 751
    , 764 (5th Cir. 2008).
    1.    Section 3B1.4: Use of Minors To Further the Crimes
    USSG § 3B1.4 provides for a two-level enhancement for using a minor to
    commit the offense. The application notes to § 3B1.4 explain that “using”
    “includes directing, commanding, encouraging, intimidating, counseling,
    training, procuring, recruiting, or soliciting.” USSG § 3B1.4 cmt. n.1. The
    district court enhanced Girod’s sentence by two levels under § 3B1.4 for using
    her underage children to complete fraudulent Medicaid forms. At sentencing,
    the district court stated that it relied on Scott’s testimony that Girod used her
    children to create the false PCS time sheets. Girod argues that Scott’s testimony
    did not show that Girod directed her children to falsify Medicaid forms but
    rather that it was that Scott, Girod, and Girod’s children all sat together and
    copied the false forms, and that Scott did not testify that Girod directed her
    children to complete the forms.
    Scott testified that she, Girod, and two of Girod’s children were in the
    kitchen filling out false PCS forms. Girod and her two children were already
    filling the forms out when Scott arrived and sat down to help. She testified that
    they all copied off of other forms or old papers. These false PCS forms were then
    submitted to ANBNO. This is more than enough to support the district court’s
    finding that Girod “used” her minor children to commit the charged offenses.
    See United States v. Mata, 
    624 F.3d 170
    , 175–77 (5th Cir. 2010) (explaining the
    case law). Scott testified that Girod’s children were much more than mere
    passive observers of Girod’s criminal acts; rather, Girod took “some affirmative
    16
    Nos. 10-30128, 10-30339
    action to involve” her minor children in actively creating fraudulent PCS time
    sheets. 
    Id. at 176.
          2.     Section 3C1.1: Obstruction of Justice
    Finally, Girod challenges her two-level enhancement under § 3C1.1 for
    obstruction of justice for lying to investigators. Girod argues there is no evidence
    she impeded the investigation because the agents investigating her had
    completed most of their investigation before they interviewed her and they came
    to their interview “armed with documentation to confront” her if she made
    statements contrary to what the agents believed happened. In essence, Girod
    argues “no harm, no foul”: that, by the time she made her (admittedly) false
    statements, the investigation had so progressed that her false statements “did
    not hamper the investigation.” This argument lacks merit. Section 3C1.1 also
    provides for a two-level enhancement for attempted obstruction or impeding
    justice.   There does not seem to be any dispute that Girod made false
    statements, and that these statements at a minimum reflected her attempt to
    impede the investigation.
    Furthermore, the commentary to § 3C1.1 states that “[t]his adjustment
    also applies to any other obstructive conduct in respect to the official
    investigation, prosecution, or sentencing of the instant offense where there is a
    separate count of conviction for such conduct.” USSG § 3C1.1 cmt. n.4. Girod
    was convicted of making three false statements to federal investigators
    regarding whether ANBNO employees provided PCS services to her children and
    whether she received kickbacks for signing-off on the false PCS sheets for her
    children, and these convictions formed the basis for her § 3C1.1 enhancement.
    While Girod points to commentary note 4's example of covered conduct (G),
    which includes “providing a materially false statement to a law enforcement
    officer that significantly obstructed or impeded the official investigation or
    prosecution of the instant offense,” note 4 is equally clear that its list of covered
    17
    Nos. 10-30128, 10-30339
    conduct is “non-exhaustive” and that, as explained above, the enhancement also
    applies when there are separate convictions for obstructive conduct. USSG
    § 3C1.1 cmt. n.4.
    We accordingly affirm Girod’s sentence.
    D.    Testimony of Langley’s Other Acts
    We “review a district court’s evidentiary rulings for abuse of discretion,”
    subject to harmless-error analysis. United States v. Cantu, 
    167 F.3d 198
    , 203
    (5th Cir. 1999). “[F]or any of the evidentiary rulings to be reversible error, the
    admission of the evidence in question must have substantially prejudiced [the
    defendant’s] rights.” United States v. Sanders, 
    343 F.3d 511
    , 519 (5th Cir. 2003).
    Langley appeals her convictions on the basis that the district court abused its
    discretion when it allowed the Government to present testimony that Langley
    provided alcoholic beverages and marijuana to two PCS clients under Federal
    Rule of Evidence 404(b) as either intrinsic or extrinsic evidence of health care
    fraud.
    Rule 404(b) only limits the admissibility of extrinsic evidence, not intrinsic
    evidence. See United States v. Sumlin, 
    489 F.3d 683
    , 689 (5th Cir. 2007).
    “Evidence of an act is intrinsic when it and evidence of the crime charged are
    inextricably intertwined, or both acts are part of a single criminal episode, or it
    was a necessary preliminary to the crime charged.” 
    Id. “Intrinsic evidence
    is
    admissible to complete the story of the crime by proving the immediate context
    of events in time and place” and to “evaluate all of the circumstances under
    which the defendant acted.” United States v. Rice, 
    607 F.3d 133
    , 141 (5th Cir.
    2010) (internal quotation marks and citations omitted). If evidence is extrinsic,
    Rule 404(b) and United States v. Beechum, 
    582 F.2d 898
    (5th Cir. 1978) (en
    banc), require that we first determine “that the extrinsic evidence is relevant to
    an issue other than the defendant’s character, i.e., motive, opportunity, intent,
    preparation, plan, knowledge, identity, or absence of mistake or accident.”
    18
    Nos. 10-30128, 10-30339
    
    Sanders, 343 F.3d at 518
    . “Second ‘the evidence must possess probative value
    that is not substantially outweighed by its undue prejudice and must meet the
    other requirements of Rule 403.’” 
    Id. (quoting United
    States v. Anderson, 
    933 F.2d 1261
    , 1269 (5th Cir. 1991)).
    Langley was charged with conspiracy and with thirteen counts of health
    care fraud for knowingly preparing fraudulent PCS time sheets for Medicaid
    reimbursement with the intent to defraud. Langley’s theory of defense was that
    she was just doing what she had been told to do when she filled out her time
    sheets, and that she did not know it was wrong or fraudulent to record times and
    activities she did not actually perform—that is, that she lacked the specific
    intent to defraud. At trial, Langley testified that: she “took care” of her PCS
    charges; she did not know anything illegal was going on; that she did not know
    she was doing anything wrong; and Lee made her change her time sheets so
    Medicaid would accept them and they all would get paid. Langley testified that
    she “put in the time” with her PCS clients listed on the time sheets and worked
    more than the hours claimed, but that the specific times and activities listed
    were not always accurate. She testified that she “never questioned Akasia Lee
    on anything, I just did my job.” She further testified that she never saw her
    clients’ POCs and was never instructed to follow a POC.
    The Government introduced evidence that Langley’s PCS clients smoked
    marijuana and drank alcohol in her care. To prove its case, the Government had
    Joyce and Jonus Perrier, two of Langley’s former PCS clients who were 13-years
    old when Langley committed her crimes, testify. Joyce Perrier testified that
    when Langley was supposed to be providing PCS services in their home, she
    brought Joyce and Jonus over to her house where Joyce watched television and
    Jonus smoked marijuana with Langley’s boyfriend. She also testified that
    Langley gave her alcohol. Jonus testified that Langley brought them over to her
    house and that he smoked marijuana and drank alcoholic beverages at her
    19
    Nos. 10-30128, 10-30339
    house. The Government claimed that this evidence was necessary to prove
    Langley’s specific intent to commit health care fraud and that she knew that the
    “services” she provided could never be mistaken as Medicaid-reimbursable PCS.
    After a hearing on the motion (among other motions in limine), the district court
    issued a written order that, inter alia, granted the Government’s motion in
    limine to admit the testimony without specifying the theory under which it was
    allowing the evidence.
    This testimony is not intrinsic to Langley’s crimes.        The “criminal
    episodes” charged were Langley’s fraudulent completion and submission of the
    PCS time sheets for the children in her care, which occurred separate from when
    Joyce and Jonus engaged in the illicit activities at Langley’s home. Evidence of
    drug and alcohol use in Langley’s home, therefore, is not part of a “single
    criminal episode,” nor does it “complete the story of the crime by proving the
    immediate context of events in time and place.” While the Government argues
    that the drug and alcohol use is “inextricably intertwined” with the crimes
    charged and helpful to “evaluate all of the circumstances under which” Langley
    acted, the drug and alcohol use is much more removed in time and space
    from—and significantly less similar than—the criminal acts charged in other
    cases in which we have found other-acts evidence to be intrinsic. See 
    Rice, 607 F.3d at 141
    –42 (finding that the defendants’ four unsuccessful robbery attempts
    were intrinsic to the crime charged of carjacking the same night); United States
    v. Coleman, 
    78 F.3d 154
    , 156 (5th Cir. 1996) (holding that evidence that the
    defendants had attempted to carjack two other luxury cars on the same day
    before carjacking a Mercedes—the crime charged—was intrinsic).
    Nor does the evidence of drug and alcohol use closely go to the conspiracy
    charge, a crime for which we have given greater latitude in classifying evidence
    as intrinsic. See United States v. Brown, 399 F. App’x 455, 460 (5th Cir. 2010)
    (per curiam) (unpublished) (ruling that the defendants’ drug use was intrinsic
    20
    Nos. 10-30128, 10-30339
    to a conspiracy to steal mail, because the conspiracy’s origin was a desire to
    obtain financial information from the mail in order to purchase merchandise
    that would later be traded for drugs); United States v. Watkins, 
    591 F.3d 780
    ,
    784–85 (5th Cir. 2009) (finding no plain error where a district court admitted as
    intrinsic evidence that the defendant admitted involvement in prior drug runs
    to establish how a cocaine conspiracy was structured and operated, and
    explaining that other-acts evidence may be admissible in conspiracy cases).
    Rather, the evidence relates to Langley’s mental state when she filled out the
    PCS time sheets, which is extrinsic to the individual health care fraud counts.
    While we remain skeptical that the Perriers’ testimony would pass a Rule
    403 analysis as required for extrinsic evidence under Beechum and Rule 404(b),
    we need not decide whether the district court abused its discretion in admitting
    the evidence because its admission was nevertheless harmless and did not
    substantially prejudice Langley’s rights.      Joyce’s and Jonus’s testimony
    regarding drug and alcohol use at Langley’s home was only one portion of their
    testimony, which focused on what PCS services Langley did not do for them.
    Langley and two of her adult children contradicted the Perriers’ testimony and
    testified that no alcohol or drugs were ever served in Langley’s home. In closing,
    the Government mentioned Joyce’s and Jonus’s testimony about alcohol and
    drug use only very briefly, and emphasized that the case was about Langley
    lying on her PCS forms and not about Langley being confused about what
    constituted PCS services. Compared to all the evidence presented against
    Langley, Joyce’s and Jonus’s testimony about marijuana and alcohol was given
    very little time at trial. Given the relatively small portion of the Government’s
    case against Langley that it constituted, its admittance at trial was harmless.
    III. CONCLUSION
    For the foregoing reasons, Girod’s, Brown’s, and Langley’s convictions
    and sentences are affirmed.
    21
    Nos. 10-30128, 10-30339
