    Appeal from the United States District Court
    for the Northern District of Illinois, Eastern Division.
    No. 05 CR 165—Elaine E. Bucklo, Judge.
    ____________
    ARGUED JANUARY 25, 2008—DECIDED MAY 1, 2008
    ____________
    Before BAUER, WOOD and EVANS, Circuit Judges.
    BAUER, Circuit Judge. Rafal Wantuch was indicted
    on charges of conspiracy to defraud the United States,
    bribery of a public official, fraudulent receipt of temporary
    Alien Registration Stamps, and making false statements
    to the (now defunct) Immigration and Naturalization
    Service (“INS”). Much of the evidence admitted at trial
    consisted of various recorded conversations between
    Wantuch and a cooperating witness, his co-conspirators,
    and undercover officers, from March of 1999 to October
    of 2000. A jury convicted Wantuch on all four counts. The
    district court sentenced Wantuch to 63 months’ imprison-
    2                                               No. 06-3681
    ment on each count, to be served concurrently. Wantuch
    appeals, challenging various evidentiary rulings by the
    district court and the jury instructions. We affirm.
    I. Background
    In 1998, the FBI, INS and Social Security Administra-
    tion initiated a joint investigation called “Operation
    Golden Schemes,” which focused on the criminal activities
    within Chicago’s Eastern European community, particu-
    larly the marketing of fraudulent immigration documents.
    The FBI opened an undercover travel agency called G.S.
    Golden Travel (“GSGT”), located in a small two-story
    building on Belmont Avenue in Chicago. GSGT had a
    sign on the door that read “By appointment only,” and
    was wired for audio and video surveillance. The FBI
    monitored GSGT from an adjacent storefront, and enlisted
    the services of several individuals: cooperating witness
    Gregory Sienkiewicz, a convicted felon with important
    connections within the eastern European Chicago com-
    munity; undercover INS official Clarence Robinson, posing
    as a corrupt INS official who sold authentic green cards
    to illegal immigrants in exchange for bribes; Tommy
    Stevens, another undercover INS official who assisted
    clients in obtaining fingerprints for the green card applica-
    tions; and (among others) FBI agents Michael Rogers
    and Robert Kowalski, who conducted surveillance at
    GSGT.
    As part of the investigation, Sienkiewicz spread the word
    (with the help of official business cards) throughout
    the criminal community that he had plenty of financial
    resources to spend on contraband and stolen goods,
    and that he was running an illegal green card operation
    No. 06-3681                                                3
    out of GSGT. (The business card was less explicit about the
    illegal aspects of the business). The cover story was that
    Sienkiewicz made an INS connection while he was in
    prison, which led him to partner with a crooked INS
    official (Robinson) who was willing to accept a bribe of
    $5,000 in order to issue green cards to illegal immigrants.
    After word got out in the community about GSGT,
    “brokers” began contacting Sienkiewicz, seeking green
    cards for their illegal immigrant “clients” in Chicago.
    Brokers and their clients would make appointments at
    GSGT, bringing with them identification, fingerprints
    (obtained from Tommy Stevens) and medical examina-
    tion records. Sienkiewicz acted as a liaison between the
    brokers and Robinson, and took a portion of the payments
    that the brokers received from their clients. Sienkiewicz
    would take them to Robinson’s office, where Robinson
    would conduct an interview and pretend to sell green
    cards. He instructed the client to make false representa-
    tions on INS forms, namely that the client was being
    sponsored by an immediate family member who was a
    United States citizen, and to state that the interview
    was not conducted at GSGT, but at the INS office at
    10 West Jackson, in downtown Chicago. At the end of the
    interview, he placed an official INS I-551 stamp on each
    client’s passport.
    In March of 1999, the FBI received information that a
    man had thirty boxes of contraband cigarettes for sale,
    and he was looking for a buyer. Sienkiewicz met the
    seller, who turned out to be Wantuch, at a building in
    northwest Chicago. (Wantuch, a native of Poland, legally
    obtained a green card when he came to the United States
    in 1993.) Wantuch offered to sell the cigarettes for $15,000.
    Wantuch and Sienkiewicz went back to GSGT where
    4                                                  No. 06-3681
    Sienkiewicz gave Wantuch the cash. Wantuch told
    Sienkiewicz that he had “other merchandise,” if
    Sienkiewicz needed anything, and that Wantuch would
    call him to conduct business in the future.
    On May 19, 1999, Wantuch sold another box of contra-
    band cigarettes to Sienkiewicz for $250. Wantuch also
    offered to sell Sienkiewicz stolen cars, liquor and other
    hot merchandise. Wantuch lamented that he was broke
    and needed to make more money, and asked Sienkiewicz
    if he needed or wanted anything. The discussion turned
    to green cards, and Wantuch lowered his voice and in-
    quired about whether there were “bugs.” He discussed
    the possibility of working with Sienkiewicz to bring in
    clients to obtain green cards. They talked about details,
    confirming that Sienkiewicz’s “partner” Robinson re-
    quired $5,000 and Sienkiewicz would receive fifty percent
    of the profits. Wantuch said that he already had a client
    lined up who would pay $12,000 for a green card.
    Wantuch soon became quite the successful broker,
    acquiring as many as fourteen clients from July of 1999 to
    April of 2000, to purchase green cards.1 He charged his
    clients between $5,000 to $13,000 in cash, above and
    beyond the $5,000 bribe paid to Robinson. Wantuch
    attended the interviews with his clients at GSGT, where
    Robinson gave blank INS forms to Wantuch’s clients,
    instructed them to falsely claim that they were spon-
    sored by immediate family members who were United
    States citizens and told them that they were already
    approved by the INS. During these interviews (caught on
    1
    Wantuch’s clients paid a total of $70,000 in bribes to Robinson.
    Wantuch paid Sienkiewicz a total of $14,500 in “kickbacks.”

    videotape by the FBI), Wantuch assisted in coaching his
    clients to make the false representations.
    Jurgita Savickiene was one of Wantuch’s clients. She
    and her sister, Lina, were illegal immigrants from Lithua-
    nia. In October of 1999, they heard about Wantuch’s
    INS connection, and went to Wantuch’s apartment to fill
    out the paperwork. Jurgita asked Wantuch how the pro-
    cess worked, and Wantuch explained to her that she
    would have to obtain fingerprints, a medical examination,
    and go to GSGT to meet the immigration officer who
    would place a stamp on her passport. Wantuch told
    Jurgita that it did not matter what her actual immigration
    status was, and that she was “pretty much safe.” Jurgita
    said she would think about it, and Wantuch responded
    that the “immigration guy” would be raising his prices.
    Jurgita eventually agreed to pay Wantuch for a green card.
    She went to Wantuch’s apartment on November 3, 1999,
    to fill out the paperwork, and they agreed on a price of
    $13,000. Jurgita gave Wantuch $3,000 as a down payment.
    Wantuch later called her to say he had made an appoint-
    ment for her at GSGT and to bring the remaining $10,000
    in cash with her.
    On December 13, 1999, Wantuch and Jurgita arrived
    at GSGT with the paperwork. Jurgita testified that she
    knew that the travel agency was not an INS facility. During
    the meeting, in which Sienkiewicz was present, Wantuch,
    Jurgita, and Robinson went over her paperwork. Robinson
    told her that if she was ever asked, to say that her sister
    was a U.S. citizen and her immigration interview was
    conducted downtown at the INS office. Wantuch agreed,
    and also told her, “Just don’t worry about anything, just
    go to the line for the U.S. citizens in the airport . . . just
    don’t go to the visitor’s . . . everything is going to be in
    6                                                  No. 06-3681
    the computer.” Robinson stamped her passport. Wantuch
    took the cash from Jurgita, gave $5,000 to Robinson and
    $2,000 to Sienkiewicz, and placed the remainder of the
    cash in his sock.
    Gregorz Gudanowski, an illegal immigrant from
    Poland, was Wantuch’s fourteenth and final client.
    Gudanowski was introduced to Wantuch by a friend,
    and met with him in February of 2000 to discuss
    Gudanowski’s immigration problems.2 Wantuch told
    Gudanowski that he could get a green card in six months
    for $20,000. Gudanowski thought the price was too high.
    Wantuch lowered his price to $16,000, and Gudanowski
    agreed to pay. On March 10, 2000, Gudanowski met
    Wantuch at the INS fingerprint office where Tommy
    Stevens worked, and gave Wantuch a down payment of
    $2,000. Wantuch set up an appointment at GSGT on
    April 19, 2000, and instructed Gudanowski to bring
    $10,000 cash, his paperwork, and passport. During the
    meeting in Robinson’s office, Robinson stamped Gudanow-
    ski’s passport and told him that, if anyone asked, he
    was interviewed at the INS office on Jackson. Wantuch
    told Gudanowski that “in case anyone ever asks you,
    you were at . . . West Jackson . . . downtown, Chicago.
    That’s where you got this stamp.” Wantuch told Robinson
    2
    Gudanowski had exhausted all legal means to obtain docu-
    ments. In 1994, he hired an attorney and attempted to obtain
    employer sponsorship, but his efforts failed. He voluntarily
    left the United States in 1999, and returned illegally in January
    of 2000. When he was told by an attorney that it would cost
    $6,000 and take about five or six years to obtain a green card,
    he sought other, faster ways to obtain a green card. Enter:
    Wantuch.
    No. 06-3681                                                  7
    that Gudanowski did not have any relatives in the United
    States, to which Robinson responded, “Yes you do . . .
    you’re his brother” and gestured to Wantuch. Wantuch
    agreed, stating “yeah, ok” and “in case anyone asks
    you, then say brother.” Sienkiewicz told Wantuch to
    explain everything to Gudanowski later, to which Wantuch
    responded, “yeah.” Gudanowski placed $10,000 on the
    chair and left. Wantuch paid Robinson $5,000, Sienkiewicz
    $2,500, and pocketed the remaining $2,500. Gudanowski
    never received his green card, and in 2003, he received
    a notice of deportation from the INS.
    In mid-2000, Wantuch attempted to contact Sienkiewicz,
    who did not return Wantuch’s phone calls for two months.
    They finally spoke on September 9, 2000. In a recorded
    conversation, Wantuch anxiously told Sienkiewicz that
    he had procured many new clients, some of whom already
    gave him a down payment for green cards. Sienkiewicz
    told Wantuch that he had put the INS business on hold,
    and to stop contacting Tommy Stevens. Wantuch promised
    to stop, explaining that he only contacted Stevens be-
    cause he had not heard from Sienkiewicz.
    In October of 2000, the FBI recorded a meeting with
    Wantuch and Robinson at GSGT. Wantuch complained
    that he could not reach Robinson since the business had
    slowed down, and he told Robinson that he had six
    more clients. Robinson explained that the INS was con-
    ducting an audit, but he was still in business, just taking
    things slowly. Robinson told Wantuch that “we don’t
    want nobody goin’ to jail.” Wantuch responded, “Of
    course!”
    On February 17, 2005, Wantuch was charged in a four
    count indictment: (1) conspiracy to defraud the United
    States in violation of 
    18 U.S.C. § 371
    ; (2) bribery of a public
    8                                                   No. 06-3681
    official in violation of 
    18 U.S.C. § 201
    (b)(1)(A) and (2);
    (3) fraudulent receipt of temporary alien registration
    stamps, in violation of 
    18 U.S.C. § 1546
    ; and (4) making
    false statements to the INS, in violation of 
    18 U.S.C. § 1001
    (a)(2) and (2).
    The government’s theory was that between March of
    1999 and April of 2000, Wantuch conspired with
    Gudanowski and his other “clients” to defraud the govern-
    ment by obtaining temporary green card stamps through
    bribes to an INS officer and false statements on green
    card applications. Prior to trial, the government sub-
    mitted a written Santiago3 proffer, which set forth the facts
    supporting the admission of relevant portions of the tape
    recorded conversations from 1999 to 2000 depicting
    Wantuch’s involvement in Operation Golden Schemes,
    pursuant to the Federal Rule of Evidence 801(d)(2)(E).
    Wantuch filed no objections.
    At trial, the aforementioned facts were introduced
    through nine witnesses called by the government, includ-
    ing Sienkiewicz, Robinson, Jurgita, and Gudanowski. The
    3
    Under United States v. Santiago, 
    582 F.2d 1128
     (7th Cir. 1978),
    overruled on other grounds by Bourjaily v. United States, 
    483 U.S. 171
    , 
    107 S.Ct. 2775
    , 
    97 L.Ed.2d 144
     (1987), the statements of
    unindicted coconspirators are admissible as non-hearsay if
    the government proves prior to trial that a conspiracy existed,
    that the defendant and the declarant were members of the
    conspiracy, and that the statements were made during the
    course and in furtherance of the conspiracy. The admissibility
    of the coconspirator statements is subject to the trial court’s
    “later determination that the government proved these foun-
    dational elements at trial.” United States v. Blanding, 
    53 F.3d 773
    , 777 (7th Cir. 1995).

    government also successfully moved to admit into evi-
    dence the audio and video taped conversations involving
    Wantuch, recorded on March 17, 1999, May 19, 1999,
    September 22, 1999, December 13, 1999, April 19, 2000,
    September 9, 2000, and October 4, 2000.
    Wantuch testified in his own defense. He denied any
    wrongdoing, claiming that Sienkiewicz hired him to
    work for GSGT as an interpreter and office helper, and
    that Sienkiewicz told him that the INS wanted to sell
    immigration benefits on the black market in order to raise
    funds for the modernization of its computers for Y2K.
    Wantuch denied he was committing a crime during the
    March 17, 1999 and May 19, 1999 cigarette transactions,
    claiming he was moving the cigarettes for a friend. He also
    denied that he offered to get or sell Sienkiewicz guns or
    other stolen merchandise. He was shown video footage
    of the meetings at GSGT with his “clients” and Robinson,
    and admitted that he instructed and encouraged his
    clients to lie about having a United States citizen relative
    as green card sponsors, and to lie about having received
    their I-551 stamps at 10 West Jackson. However, Wantuch
    claimed that he only told his clients to lie because
    Sienkiewicz and Robinson told him to do so.
    When asked about the payment of money on the
    video between Wantuch, Robinson and Sienkiewicz,
    Wantuch claimed that he was merely acting as a go-
    between for his clients. He denied making payoffs to
    Sienkiewicz, and said Sienkiewicz was actually paying
    Wantuch, since he was on the payroll at the office. He
    also admitted that he knew the proper location to obtain
    a green card was 10 West Jackson, and not GSGT, as
    he went through the application process and obtained a
    legal green card in 1993 when he immigrated to the
    10                                              No. 06-3681
    United States. He also testified that he paid much less than
    $16,000—the amount he charged Gudanowski—to legally
    obtain his green card.
    A jury convicted Wantuch on all four counts of the
    indictment. Wantuch was sentenced to 63 months’ impris-
    onment on each count, to be served concurrently. This
    timely appeal followed.
    II. Discussion
    Wantuch raises four issues on appeal that we will
    address: (1) whether the district court erred by allowing
    Sienkiewicz and Robinson to testify as to their opinion
    of Wantuch’s intent under Federal Rule of Evidence 701;
    (2) whether the court erred in admitting testimony about
    a confrontation between Gudanowski and Wantuch in
    2003; (3) whether the court erred in admitting evidence of
    the cigarette sales between Wantuch and Sienkiewicz; and
    (4) whether the evidence of a conspiracy was sufficient to
    warrant a Pinkerton instruction.4 We address each argu-
    ment in turn.
    A. Opinion Testimony
    At trial, Sienkiewicz testified about Wantuch’s role in
    the green card scheme, including Wantuch’s acquisition
    of fourteen clients, and a total of $70,000 paid to Robinson
    in exchange for the green cards. The jurors were presented
    4
    Wantuch makes other arguments pertaining to the ade-
    quacy of the jury instructions. We have considered all of his
    challenges and have found them to be without merit.
    No. 06-3681                                            11
    with audio and video recordings of all of the conversa-
    tions between Wantuch and Sienkiewicz from March of
    1999 to September of 2000. Near the end of his testimony,
    the government asked:
    Q: Mr. Sienkiewicz, at all times that you were dealing
    with Wantuch, was he aware that paying [Robin-
    son] those $5,000 in exchange for the green cards
    was illegal?
    Defense counsel objected, and after the court heard argu-
    ments from both sides on whether to allow the opinion
    testimony at a sidebar, the court overruled the objection
    and Sienkiewicz answered:
    A: I think we must be kidding here. This gentleman
    knew all the time that everything that he was
    doing was illegal. One does not buy a green card
    on the street for money. Come on, let’s stop pre-
    tending here. We are not little people, are we?
    Robinson also testified about his dealings with Wantuch
    and the clients that Wantuch brought into GSGT. The
    government played the video recording from December 13,
    1999, the day that Wantuch brought Jurgita into GSGT
    for an interview. After the jury watched the video, the
    government handed Robinson a transcript of the recording:
    Q: I want to refer you to line 37, still on page 6. Did
    Wantuch say “If somebody asked you?”
    A: Yes.
    Q: And in response to that, you said: “If anybody
    asked you, because when you’re in our airports,
    sometimes they ask you, you know, and you come
    to the U.S. citizen’s line.”
    A: Yes.
    12                                             No. 06-3681
    Q: What was your understanding of what Wantuch
    was doing during that conversation?
    A: He was saying that—telling her that she did have
    a sister . . . that petitioned for her.
    Defense counsel objected after Robinson answered,
    stating “the words speak for themselves.” The court asked
    the government to repeat the question, but the govern-
    ment moved on to another line of questioning. Later, the
    government asked Robinson:
    Q: Some of the procedures in the interview that we
    watched on that video were the same as some
    of the procedures that are followed legitimately at
    10 West Jackson, correct?
    A: Yes they [were].
    Q: Now, when you use the word “legitimate,” is it
    your understanding that the brokers, specifically
    Wantuch, understood that this was a legitimate
    transaction?
    A: No he did not.
    Defense counsel failed to object to this testimony.
    Wantuch argues that Sienkiewicz and Robinson’s testi-
    mony as to Wantuch’s state of mind should have been
    excluded because it was not rationally based on their
    perception of Wantuch, and their testimony was neither
    helpful to the jury nor necessary for the jury’s review of
    the evidence, under Federal Rule of Evidence 701. He also
    argues that the unfair prejudice of the testimony vastly
    outweighed any probative value it had under Rule 403.
    We have held that lay opinion testimony regarding
    mental states is admissible under Rule 701. United States v.
    No. 06-3681                                                 13

    , 699 (7th Cir. 1987); Bohannon v.
    Pegelow, 
    652 F.2d 729
    , 732 (7th Cir. 1981). However, there
    are limits to its admissibility. Rule 701 provides:
    If the witness is not testifying as an expert, the witness’
    testimony in the form of opinions of inferences is
    limited to those opinions or inferences which are
    (a) rationally based on the perception of the witness
    and (b) helpful to a clear understanding of the wit-
    ness’ testimony or the determination of a fact in issue.
    See also Fed. R. Evid. 704(a) (“Testimony in the form of
    an opinion or inference otherwise admissible is not objec-
    tionable because it embraces an ultimate issue to be
    decided by the trier of fact.”). The considerations outlined
    in Rule 403 also apply—lay opinions may be excluded if
    the opinion would be a waste of time or its probative value
    is substantially outweighed by its prejudicial nature.

    ; Fed. R. Evid. 704 Advisory
    Committee Note on 1972 Proposed Rules.
    Rule 701(a)’s requirement that the opinion be rationally
    based on the witness’s perception is “the familiar require-
    ment of first-hand knowledge or observation.” Rule 701(a)
    Advisory Committee Note; see also Fed. R. Evid. 602 (“A
    witness may not testify to a matter unless evidence is
    introduced sufficient to support a finding that the witness
    has personal knowledge of the matter.”). Rule 701(b)
    assures against the admission of opinions which would
    merely tell the jury what result to reach. Fed. R. Evid. 704
    Advisory Committee Note on 1972 Proposed Rules. Lay
    opinion testimony is admissible only to help the jury or
    the court to understand the facts about which the witness
    is testifying. United States v. Conn,

    A decision to admit lay opinion testimony is com-
    mitted to the district court’s discretion and is reversed
    only for abuse of that discretion. United States v. Espino,

    , 257 (7th Cir. 1994); United States v. Stormer,
    
    938 F.2d 759
    , 761 (7th Cir. 1991). A determination made
    by a trial judge regarding the admissibility of evidence is
    treated with great deference because of the trial judge’s
    first hand exposure to the witnesses and the evidence as a
    whole, and because of her familiarity with the case and
    ability to gauge the likely impact of the evidence in the
    context to the entire proceeding. Bogan, 
    267 F.3d at 619
    .
    Further, even erroneous evidentiary rulings will not be
    overturned if any resulting error was harmless. United
    States v. Chavis, 
    429 F.3d 662
    , 667 (7th Cir. 2005). With those
    standards in mind, we turn first to Wantuch’s argument
    that the admission of Sienkiewicz’s testimony violated
    Rule 701.
    Because Wantuch properly objected to Sienkiewicz’s
    testimony, we review the portion of his testimony for an
    abuse of discretion. The evidence sufficiently demonstrated
    that Sienkiewicz’s opinion testimony was rationally
    based on his perception. Prior to Sienkiewicz’s comment
    that Wantuch was aware his conduct was “illegal,” the
    government elicited testimony from Sienkiewicz about his
    interactions with Wantuch from March of 1999 to Septem-
    ber of 2000. Sienkiewicz was deeply involved in the green
    card scheme; he was Wantuch’s contact every step of the
    way. Sienkiewicz testified about his initial meetings
    with Wantuch in March and May of 1999, in which
    Wantuch sold Sienkiewicz contraband cigarettes, and
    discussed details of the scheme to obtain green cards in
    exchange for paying bribes to an INS official. Sienkiewicz
    was present at the meetings with Robinson, Wantuch, and
    No. 06-3681                                               15
    Wantuch’s clients and observed Wantuch coach his clients
    to make false statements on the INS forms and to make
    further false statements if they were ever questioned by
    INS officials. Sienkiewicz also observed Wantuch accept
    money from his clients, hand over payments to Robinson
    in exchange for stamping his clients’ passports, and share
    the profits with Sienkiewicz. Therefore we find that
    Sienkiewicz’s opinion testimony about Wantuch’s knowl-
    edge of the illegality of his actions was rationally based on
    his perception. See United States v. Rea, 
    958 F.2d 1206
    ,
    1216 (2d Cir. 1992) (“Lay opinion testimony regarding a
    defendant’s knowledge will, in most cases, only satisfy
    the rationally-based requirement if the witness has per-
    sonal knowledge of one or more objective factual bases
    from which it is possible to infer with some confidence
    that a person knows a given fact . . . includ[ing] what the
    person was told directly, what he was in a position to see
    or hear, what statements he himself made to others,
    conduct in which he engaged, and what his background
    and experience were.”) (internal quotations omitted).
    But this testimony was unhelpful to the jury under
    Rule 701(b). Attempts to introduce meaningless asser-
    tions which amount to little more than choosing up sides
    require exclusion for lack of helpfulness by Rule 701.
    Rule 701(b) Advisory Committee Note on 1972 Proposed
    Rules. The question posed to Sienkiewicz to opine as to
    Wantuch’s knowledge of whether his actions were “legal,”
    demanded a conclusion as to the legality of Wantuch’s
    conduct, which is unhelpful to the jury under Rule 701. See
    United States v. Espino, 
    32 F.3d 253
    , 257 (7th Cir. 1994)
    (finding that the question posed to a defendant, “you’re
    admitting to a conspiracy, aren’t you,” was unhelpful
    testimony under Rule 701); United States v. Baskes, 649
    16                                              No. 06-
    3681 F.2d 471
    , 478 (7th Cir. 1980) (when a witness is asked
    whether the conduct in issue was “unlawful” or “willful”
    or whether the defendants “conspired,” terms that demand
    an understanding of the nature and scope of the criminal
    law, the trial court may properly conclude that any re-
    sponse would not be helpful to the trier of fact under
    Rule 701(b)).
    We note that the question posed by the government was
    unnecessary, in light of all of the evidence against Wantuch
    that the government presented through Sienkiewicz’s
    testimony. The jury was just as capable as Sienkiewicz
    of inferring that Wantuch knew he was committing a
    crime, without Sienkiewicz opining as to whether Wantuch
    was aware that his conduct was illegal. See Rea, 
    958 F.2d at 1216
    .
    Nevertheless, reversal, the relief which Wantuch seeks,
    is not required where the error is harmless. Fed. R. Crim.
    Pro. 52(a). We see no reasonable possibility that
    Sienkiewicz’s statement had a substantial and injurious
    effect or influence on the jury’s verdict, United States v.
    Douglas, 
    408 F.3d 922
    , 929 (7th Cir. 2005), in light of the
    overwhelming evidence presented against Wantuch,
    including video and audio tapes of seven different en-
    counters in which Wantuch could be seen or heard partici-
    pating in illegal activity, interlocking testimony of nine
    government witnesses, and Wantuch’s own admissions.
    When viewed in the context of the entire trial and the
    totality of the evidence, the jury heard substantial evidence
    to support the government’s theory at trial, and although
    the district court erred in admitting Sienkiewicz’s state-
    ment, the error was harmless.
    Wantuch makes the same arguments under Rule 701
    regarding the admission of Robinson’s testimony. Because
    No. 06-3681                                                   17
    Wantuch failed to contemporaneously object (or state
    specific grounds for his objections) to any of Robinson’s
    testimony of which he now complains, we review Robin-
    son’s testimony for plain error. See Fed. R. Evid. 103(a)(1);
    United States v. Swan, 
    486 F.3d 260
    , 263 (7th Cir. 2007).
    Under plain error review, an error must be “clear or
    obvious” and “affect substantial rights” in order to warrant
    reversing the district court’s decision to admit the evi-
    dence. United States v. Schalk, 
    515 F.3d 768
    , 776 (7th Cir.
    2008) (citation omitted). We will not correct any error
    unless it “seriously affect[s] the fairness, integrity, or public
    reputation of the judicial proceedings.” 
    Id. at 777
     (citations
    omitted).
    The district court did not plainly err in admitting
    the testimony of Robinson. In short, under Rule 701,
    Robinson had sufficient first-hand knowledge of the
    conversation with Wantuch and Jurgita, that was based on
    his direct participation, as well as his perception and
    observation of Wantuch. The jurors were presented with
    the entire video-recorded conversation between Robinson
    and Wantuch on December 13, 1999. Robinson specifically
    told Wantuch’s clients to lie on the INS forms, and he
    observed Wantuch assist him in coaching his clients to
    make false representations. See United States v. Estrada, 
    39 F.3d 772
    , 773 (7th Cir. 1994) (per curiam) (holding that a
    participant in a conversation may testify as to his under-
    standing of the conversation to satisfy Rule 701(a)’s
    requirement that the testimony be rationally based on the
    witness’s perceptions); United States v. Lizardo, 
    445 F.3d 73
    ,
    83 (1st Cir. 2006) (holding that a witness may testify
    about his subjective interpretation of a conversation
    in which he is participating as long as his opinion is
    rationally based on his perception and is helpful either to
    18                                              No. 06-3681
    an understanding of his testimony or to the determina-
    tion of a fact in issue).
    Unlike Sienkiewicz’s testimony, Robinson did not
    comment on the illegality of Wantuch’s actions. He merely
    testified to what he understood Wantuch’s comments to
    mean—and repeated what Wantuch told Jurgita—that
    if she was ever questioned by the INS, she was to say
    that she had a sister who was a legal U.S. citizen who
    petitioned for her. Such testimony also could prove helpful
    to a jury to interpret what Wantuch and Robinson were
    communicating to Jurgita during the meeting. Further-
    more, even if Wantuch was correct, the overwhelming
    weight of the case against him makes it clear that these
    alleged errors did not affect the outcome of the proceedings
    such that we should consider invoking our discretion
    under Fed. R. Crim. Pro. 52(a). United States v. Jumah, 
    493 F.3d 868
    , 875 (7th Cir. 2007) (citing United States v. Olano,
    
    507 U.S. 725
    , 732, 
    113 S.Ct. 1170
    , 
    123 L.Ed.2d 508
     (1993)).
    B. Gudanowski’s Confrontation with Wantuch in 2003
    Near the end of his testimony, Gudanowski stated that
    in 2003, after he received a deportation letter from the
    INS, he confronted Wantuch at a local tavern. The follow-
    ing colloquy took place between the government and
    Gudanowski:
    Q: What happened once you got to [the tavern]?
    A: Well, when I got there, he was sitting there and he
    was kind of very thin, unbalanced, and when
    I saw him, I was—basically, all my anger went
    away. And I asked him why he did this to me, he
    knew that it was illegal, and, you know, he was
    No. 06-3681                                                  19
    like on strong medication or something, and then
    he even offered me his own green card.
    Q: Now when you approached Mr. Wantuch and
    told him this, including why did he do this,
    what did he say in response?
    ...
    A: He didn’t basically give me a sensible answer.
    He was basically sitting there kind of looking
    guilty, and that was about it.
    Defense counsel moved to strike the term “guilty,” and the
    district court sustained the motion and instructed the
    jury accordingly.
    Wantuch sees error in the admission of Gudanowski’s
    description of his confrontation with Wantuch in 2003,
    which he characterizes as post-conspiracy statements
    that were irrelevant and prejudicial. Wantuch failed to
    object to the admission of this evidence at trial, therefore
    we review for plain error. United States v. Powers, 
    75 F.3d 335
    , 338 (7th Cir. 1996).
    Because Wantuch has presented no evidence to con-
    vince us otherwise, we presume that the jury limited its
    consideration of the testimony in accordance with the
    court’s instruction, and disregarded Gudanowski’s use
    of the term “guilty.” United States v. Mallett, 
    496 F.3d 798
    , 802 (7th Cir. 2007). Errors that are the subject of
    corrective instructions to the jury are presumed harmless.
    United States v. Moore, 
    115 F.3d 1348
    , 1358 (7th Cir. 1998);
    see also Greer v. Miller, 
    483 U.S. 756
    , 766 n.8, 
    107 S.Ct. 3102
    ,
    
    97 L.Ed.2d 618
     (1987) (“We normally presume that a
    jury will follow an instruction to disregard inadmissible
    evidence inadvertently presented to it, unless there is an
    20                                                    No. 06-3681
    overwhelming probability that the jury will be unable to
    follow the court’s instructions, and a strong likelihood
    that the effect of the evidence would be devastating to
    the defendant.”).5
    C. Introduction of Evidence of Cigarette Sales
    Wantuch argues that the court erred in admitting (1) the
    evidence of the contraband cigarette sales between
    Wantuch and Sienkiewicz, and (2) the related conversa-
    tions about other stolen merchandise. In Wantuch’s view,
    the evidence does not prove an element of any of the
    charged offenses, and thus is not inextricably inter-
    twined with the charged crimes.
    5
    Wantuch fails to develop his argument on the other aspects
    of Gudanowski’s testimony, nor does he cite any substantive
    legal authority to support his contention. It is not the obliga-
    tion of this court to research and construct the legal arguments
    open to parties, especially when they are represented by coun-
    sel. United States v. McLee, 
    436 F.3d 751
    , 760 (7th Cir. 2006)
    (internal quotations omitted). Thus his argument is waived. See
    Perez v. Illinois, 
    488 F.3d 773
    , 776-77 (7th Cir. 2007); United
    States v. Berkowitz, 
    927 F.2d 1376
    , 1384 (7th Cir. 1991) (“We
    repeatedly have made clear that perfunctory and undeveloped
    arguments . . . are waived [on appeal].”). In any event, we
    find the admission, if error, to be harmless, failing to have “a
    substantial and injurious effect or influence on the jury’s
    verdict.” United States v. Thomas, 
    86 F.3d 647
    , 655 (7th Cir. 1996).
    The government presented overwhelming evidence of
    Wantuch’s guilt on the conspiracy and bribery charges, and
    did not attempt to use this portion of Gudanowski’s testimony
    in its closing argument. Thus, we are convinced that any
    erroneous admission of this evidence did not affect the jury’s
    ultimate decision.
    No. 06-3681                                              21
    Prior to trial, the government filed a motion in limine to
    introduce (1) evidence of Wantuch’s sale of contraband
    cigarettes to Sienkiewicz, and (2) conversations between
    Sienkiewicz and Wantuch in May of 1999, in which
    Wantuch offered to sell Sienkiewicz other stolen mer-
    chandise. Wantuch filed a written objection to the introduc-
    tion of the evidence of the cigarette sales. During a
    pretrial hearing, the district court held that evidence of
    the cigarette sales was admissible because it was “intrinsi-
    cally connected with the case” (or intricately related),
    and therefore the court did not have to “deal with [the
    admissibility of the evidence] under Rule 404(b).” The
    government then asked the court for a ruling on the
    admissibility of the other conversations between Wantuch
    and Sienkiewicz about the stolen liquor and cars. The
    court gave Wantuch a few days to raise any objections,
    but Wantuch raised none. On the first day of trial, the
    government requested a ruling on the admissibility of
    the conversations related to the stolen merchandise. The
    court stated to Wantuch, “It doesn’t sound like there’s an
    issue,” to which Wantuch responded, “No.” Wantuch
    subsequently failed to raise any objections during trial.
    First, we address Wantuch’s argument regarding the
    admission of the evidence of other stolen merchandise. The
    district court gave Wantuch a number of days to file any
    objections, which Wantuch failed to do. The court also
    directed a question to Wantuch, giving him another
    chance to object to the evidence, but Wantuch affirmatively
    stated on the record that he had no objection to the ad-
    mission of this evidence of other stolen merchandise.
    Therefore we find that Wantuch waived his objections to
    this evidence, and we decline to review the district court’s
    decision. United States v. Murry, 
    395 F.3d 712
    , 718-19 (7th
    Cir. 2005).
    22                                               No. 06-3681
    Next, we turn to the admission of the evidence of
    the contraband cigarette sales. The district court ad-
    mitted this evidence solely under the theory that it was
    intricately related to the conspiracy. This court has a well-
    established line of precedent that allows evidence of
    uncharged acts to be introduced at trial if the evidence is
    “intricately related” to the acts charged in the indictment.
    Bogan, 
    267 F.3d at 621
    . We review the district court’s
    decision to admit the evidence of the contraband cigarette
    sales under the intricately related doctrine for an abuse
    of discretion. United States v. Strong, 
    485 F.3d 985
    , 989 (7th
    Cir. 2007). Under this doctrine, whether instances of
    uncharged conduct are “intricately-related” (or “inextrica-
    bly intertwined”) to the case at hand depends on whether
    “they complete the story of the crime on trial; their
    absence would create a chronological or conceptual void
    in the story of the crime; or they are so blended or con-
    nected that they incidentally involve, explain the circum-
    stances surrounding, or tend to prove any element of,
    the charged crime.” United States v. Gougis, 
    432 F.3d 735
    , 742 (7th Cir. 2005) (citation omitted). The admissibility
    of such evidence is limited only by the balancing test set
    forth in Rule 403 and does not implicate the character/
    propensity prohibition of Rule 404(b). United States v.
    Griffin, 
    493 F.3d 856
    , 867 (7th Cir. 2007); McLee, 
    436 F.3d at 760
    ; United States v. Ramirez, 
    45 F.3d 1096
    , 1102-03 (7th
    Cir. 1995).
    Wantuch contends that the discussion of illegal sales
    of cigarettes has nothing to do with immigration docu-
    ments or elements of the charged offenses; however,
    uncharged criminal activity need not be identical to the
    charged crime in order to be admitted under the intricately
    related doctrine. Gougis, 
    432 F.3d at 743
    . Here, the evid-
    No. 06-3681                                                  23
    ence of the sale of contraband cigarettes showed how
    Wantuch’s relationship with Sienkiewicz “began, its basis
    and structure, and how the relationship blossomed into
    the charged conspiracy.” United States v. Zarnes, 
    33 F.3d 1454
    , 1469 (7th Cir. 1994). It outlined how the relationship
    of trust and cooperation between Sienkiewicz and
    Wantuch was born, developed and eventually led to their
    respective roles in the conspiracy. See United States v.
    Spaeni, 
    60 F.3d 313
    , 316 (7th Cir. 1995); see also United States
    v. Richmond, 
    222 F.3d 414
    , 417 (7th Cir. 2000) (holding that
    evidence was intricately related because it explained the
    circumstances surrounding the relationships of the
    people involved in the conspiracy). Further, the evidence
    showed that Wantuch was a willing participant in the
    sale of illegal goods (and eventually the green card
    scheme), demonstrating that he was ready to pursue any
    avenue in order to make money by offering to provide
    Sienkiewicz with any merchandise that he required.
    Wantuch argues that any probative value of the evidence
    was substantially outweighed by the danger of unfair
    prejudice under Fed. R. Evid. 403. The district court’s
    admission of evidence under Rule 403 is entitled to
    special deference. “Only in an extreme case are appellate
    judges competent to second-guess the judgment of the
    person on the spot, the trial judge.” Strong, 
    485 F.3d at 991
     (citation omitted). Evidence is unfairly prejudicial
    only if it will induce the jury to decide the case on an
    improper basis, commonly an emotional one, rather
    than on the evidence presented. 
    Id.
     The evidence was
    probative to counter Wantuch’s defense that he was
    simply hired by Sienkiewicz to work in the office at GSGT
    and help the INS by new computers for the Y2K, and
    that he did not commit a crime when he sold the contra-
    24                                                    No. 06-3681
    band to Sienkiewicz. Additionally, to minimize the risk of
    unfair prejudice, the court ensured that the jury used the
    evidence only for a legitimate purpose—Wantuch’s
    intent—when it gave a limiting instruction in the final
    jury instructions. See United States v. Whitlow, 
    381 F.3d 679
    ,
    686 (7th Cir. 2004). The evidence was properly admitted.
    D. The Pinkerton Instruction
    Wantuch further argues that the district court erred in
    giving the Pinkerton6 instruction, because the evidence at
    trial was insufficient to support the conspiracy count.
    During the jury instruction conference, the government
    proposed the pattern Pinkerton instruction:
    A conspirator is responsible for offenses committed
    by his fellow conspirators if he was a member of
    the conspiracy when the offenses were committed
    and if the offenses were committed in furtherance of
    and as a foreseeable consequence of the conspiracy.
    Therefore, if you find the defendant guilty of the
    conspiracy charged in Count 1 of the indictment and
    if you find beyond a reasonable doubt that while he
    was a member of the conspiracy, his fellow conspira-
    tors committed the offenses in Count Two, Three, and
    Four in furtherance of or as a reasonable consequence
    of that conspiracy, then you should also find the
    defendant guilty of Counts Two, Three, and Four.
    6
    Under Pinkerton, a coconspirator may be held criminally liable
    for the foreseeable overt acts of others in furtherance of a
    conspiracy. Pinkerton v. United States, 
    328 U.S. 640
    , 
    66 S.Ct. 1180
    ,
    
    90 L.Ed. 1489
     (1946); United States v. Frazier, 
    213 F.3d 409
    ,
    416 (7th Cir. 2000).
    No. 06-3681                                                25
    Because Wantuch makes this objection for the first time
    on appeal, we review the argument for plain error. United
    States v. Matthews, 
    505 F.3d 698
    , 709 (7th Cir. 2007); Fed. R.
    Crim. P. 52(b). “Defendants challenging the quantum of
    evidence supporting a jury verdict face a daunting task.”
    United States v. Wortman, 
    488 F.3d 752
    , 754 (7th Cir. 2007).
    When we review the sufficiency of the evidence, we ask
    only if, after viewing all of the evidence in a light most
    favorable to the government, and drawing all reasonable
    inferences therefrom, a rational trier of fact could not
    have found the essential elements of the crime, beyond
    a reasonable doubt. United States v. Moore, 
    446 F.3d 671
    ,
    677 (7th Cir. 2006).
    To sustain a conviction for conspiracy under 
    18 U.S.C. § 371
    , the government must prove: (1) an agreement to
    commit an offense against the United States; (2) an overt
    act in furtherance of the conspiracy; and (3) knowledge
    of the conspiratorial purpose. United States v. Soy, 
    454 F.3d 766
    , 768 (7th Cir. 2006). Wantuch argues that the
    evidence failed to show, beyond a reasonable doubt, any
    agreement between Wantuch and Gudanowski. The
    evidence proves otherwise. The nub of a conspiracy is
    an agreement, and the government can prove the agree-
    ment by showing “an understanding—explicit or implicit—
    among coconspirators to work together to commit the
    offense.” United States v. Bailey, 
    510 F.3d 726
    , 735 (7th
    Cir. 2007). A jury is not limited to direct evidence and
    may find an agreement to conspire based upon circum-
    stantial evidence and reasonable inferences drawn from
    the relationship of the parties, their overt acts, and the
    totality of their conduct. United States v. Macedo, 
    406 F.3d 778
    , 791-92 (7th Cir. 2005) (citation omitted). The record
    strongly supports the notion that Wantuch entered into
    26                                                No. 06-3681
    an agreement with Gudanowski to defraud the United
    States by any one of the substantive counts in the indict-
    ment. From the moment Gudanowski joined forces
    with Wantuch, he had exhausted his legal means of
    obtaining a green card, and his only hope for a speedy
    solution was to enlist Wantuch’s services. Wantuch’s
    actions as a broker constituted a continuing relationship
    with Gudanowski, based on the common purpose and
    agreement—to obtain green cards by paying bribes to an
    INS official. Gudanowski agreed to pay, and Wantuch
    agreed to facilitate appointments to undergo medical
    exams and obtain fingerprints, and to arrange meetings at
    GSGT with Robinson. The jury watched on video as
    Wantuch assisted Robinson in instructing Gudanowski to
    make false representations on the INS forms, such as
    claiming to have a relative who would sponsor him, and
    that if he was ever questioned, his interview took place
    at 10 West Jackson, and not at GSGT. On the stand,
    Gudanowski admitted that he lied on his application and
    that he knew GSGT was not an INS facility. Wantuch
    argues that Gudanowski’s testimony proved that he
    lacked criminal intent, but credibility determinations are
    for the jury. United States v. Williams, 
    298 F.3d 688
    , 692 (7th
    Cir. 2002) (coconspirator’s testimony sufficient to prove
    existence of a conspiracy). The jury was entitled to be-
    lieve that Gudanowski was in cahoots with Wantuch to
    illegally obtain a green card, therefore we find that the
    evidence was sufficient to find that Wantuch participated
    in the charged conspiracy.
    A Pinkerton instruction informs the jury that if they
    initially determine beyond a reasonable doubt that a
    conspiracy existed, and the defendant was a member of
    the conspiracy, then they may find him responsible for
    offenses committed by other coconspirators in the fur-
    No. 06-3681                                             27
    therance of the conspiracy. The evidence presented in this
    case sufficiently establishes Wantuch’s participation in
    the conspiracy, therefore it was appropriate for the dis-
    trict court to give the jury a Pinkerton instruction.
    III. Conclusion
    For the aforementioned reasons, the judgments of the
    district court are affirmed and the verdict against Wantuch
    stands.
