Joann A. Parker (“Mrs. Parker”) appeals her conviction and sentence for conspiracy to commit pubhc bribery and five counts of pubhc bribery in violation of 18 U.S.C. §§ 201(b)(2)(C) and 371. Ralph Parker (“Mr. Parker”) appeals his conviction for con *325 spiracy to commit public bribery and three counts of public bribery under the same statutes. We affirm.
I
The Social Security Administration (“SSA”) Office of Hearings and Appeals employed Mrs. Parker as a clerk to Administrative Law Judge (“ALJ”) John Aronson. She led a group that helped certain individuals to fraudulently obtain Supplemental Security Income (“SSI”) benefits in return for money. 1 The scheme began when Mrs. Parker met Niknitta Simmons (“Simmons”) at a hearing where Simmons was appealing the denial of SSI benefits for her son, Kevin Simmons. ALJ Aronson advised Simmons that additional documentation would be necessary for a favorable ruling on Kevin’s claim. Mrs. Parker approached Simmons after the hearing and offered to help. A few days later, Mrs. Parker gave Simmons a letter approving Kevin’s benefits. Mrs. Parker thereafter called Simmons and demanded money for her help. Simmons refused to pay, and Kevin’s benefits were terminated. Mrs. Parker advised Simmons that Kevin’s benefits would be reinstated if Simmons paid her.
Simmons went to several SSA offices and reported Mrs. Parker’s demands. Investigators from the SSA and FBI contacted Simmons, and she agreed to assist them by permitting FBI Agent Karen Jenkins to record her telephone conversations with Mrs. Parker. In multiple recorded conversations, Mrs. Parker demanded payment for having Kevin’s benefits approved initially and for having those benefits reinstated. At a meeting at Simmons’ home, Mrs. and Mr. Parker took $500, as captured on videotape by the FBI. Mrs. Parker thereafter demanded more money, which Simmons paid, and Mrs. Parker gave Simmons a letter purportedly bearing ALJ Aronson s signature reinstating Kevin’s benefits.
Agent Jenkins and a SSA agent interviewed Mrs. Parker about her contacts with Simmons. The agents advised Mrs. Parker of her rights and she signed a written waiver before confessing to fraudulently approving benefits for Kevin Simmons, Raymond Henry, Georgette Lemon, Yvette Scott, and Karen Johnson. Mrs. Parker stated that two other SSA employees had assisted her and implicated Mr. Parker. Mrs. Parker admitted that she had approved benefits by taking letters addressed to different persons, changing the names and dates of those letters to match those of the applicants who had paid her money, and forging the signature of ALJ Aronson.

Mrs. Parker first argues that the indictment charging her with conspiracy to commit public bribery and public bribery under 18 U.S.C. § 201(b)(2)(C) was deficient because she lacked the authority to grant or deny benefits. Mrs. Parker’s duties included assisting ALJ Aronson before and during the hearings, recording and taking notes at those hearings, and typing and mailing ALJ Aron-son’s decisions. Mrs. Parker had access to the office’s computer system, but was not authorized to approve benefits or sign ALJ Aronson’s name. Thus, Mrs. Parker essentially argues that the only acts which we should examine in determining whether she violated section 201(b)(2)(C) are those within the scope of her authority, such as typing and mailing opinions.
Section 201(b)(2)(C) prohibits public officials from being induced to do or omit any act in violation of their official duty.

Acts
*326
that violate an official’s duty are extremely broad in scope. Section 201(a) broadly defines an “official act” as “any decision or action on any question, matter, cause, suit, proceeding or controversy, which may at any time be pending, or which may by law be brought before any public official, in such official’s official capacity, or in such' official’s place of trust or profit.” 18 U.S.C. § 201(a)(3). This broad definition of “official act” reflects Congress’ intent to “include any decision or action taken by a public official in his capacity as such.” S.Rep. No. 87-2213, (1962),
reprinted in
1962 U.S.C.C.A.N. 3852, 3856. Official acts that violate an official’s official duty are not limited to those proscribed by statutes and written rules and regulations, but may also be found in “established usage,” because “duties not completely defined by written rules are established by settled practice, and action taken in the course of their performance must be regarded as within the provisions of the above-mentioned statutes against bribery.”
United States v. Birdsall,
Mrs. Parker does not dispute that the individuals for whom she fraudulently approved benefits had appeals pending in her office. Because the appeals were pending in her “place of trust or profit,” her actions fall within the statutory definition of “official act.”
See United States v. Dobson,
B
Mr. and Mrs. Parker argue that the district court erred in barring cross-examination of the witness Yvette Scott on pending state charges that Scott murdered her husband. At trial, they both argued that the charge was relevant to show Scott’s general lack of credibility. The court barred mention of the pending state charges because it held that “[t]hreatening to kill her husband or killing her husband has nothing to do with the facts of this case.” On appeal, Mrs. Parker argues that cross-examination should have been allowed to show Scott’s lack of credibility. Mr. Parker argues for the first time on appeal *327 that such cross-examination would have shown that Scott had an incentive to slant her testimony in this case in favor of the government to receive a favorable recommendation in the pending state ease.
As the lower court correctly noted, Fed.R.Evid. 609 permits impeachment by evidence of past convictions, but does not apply to crimes charged for which there has been no conviction.
See United States v. Abadie,
With regard to Mr. Parker’s argument that cross-examination on the pending state charges would have demonstrated possible bias, even assuming the applicability of Rule 608(b), reversal would still not be required. Mr. Parker has presented no evidence that federal prosecutors agreed to give a favorable recommendation for or intercede on behalf of Simmons in the pending state ease.
See United States v. Benavidez,
C
Mrs. Parker next argues that the district court erred in excusing venire member 47, who stated that he would have a “healthy skepticism for evidence brought into court” and that he would be suspicious of the government’s evidence before he saw it. She also avers that the judge’s questioning of venire member 47 was so loud that the entire venire could hear the questioning, and that this questioning cowed the jury into believing that they were required to accept the government’s evidence as correct.
In noncapital cases, removal of a venire member generally is not grounds for reversal unless “the jurors who actually sat were not impartial within the meaning of the Sixth Amendment.”
United States v. Gonzalez-Balderas,
Mrs. Parker has presented no evidence that the jurors who actually sat were not impartial. Indeed, even after the judge’s exchange with venire member 47, other veni-re members approached the bench to inquire about possible disqualifications. Their exchanges with the judge do not reflect any sense of intimidation by the judge’s exchange with venire member 47. The judge also instructed the jury that they should decide the case only on the evidence presented in court and according to the court’s instructions. In the absence of evidence to the contrary, we find that the jury was impartial, and that Mrs. Parker’s rights were not prejudiced.

Mr. Parker argues that the district court abused its discretion on two evi-dentiary rulings. We review evidentiary rulings only for abuse of discretion.
See United States v. Torres,
In the second ruling, Peggy Kelly testified about a telephone conversation she had with a man who referred to Mrs. Parker as his “old lady” and who threatened Kelly. Kelly stated that she thought that the man on the telephone was Mr. Parker and her reasons for so thinking, but admitted that she could not identify his voice and that she had never previously met him. Mr. Parker argues that the government therefore failed to properly establish the evidentiary foundation for the telephone conversation. “While a mere assertion of identity by a person talking on the telephone is not in itself sufficient to authenticate that person’s identity, some additional evidence, which ‘need not fall in[to] any set pattern,’ may provide the necessary foundation.”
United States v. Khan,
Here, the trial court found sufficient circumstantial evidence to indicate that the man on the telephone was Mr. Parker because Mrs. Parker placed the call to Kelly, and, thereafter, a man interrupted the telephone conversation and stated that Mrs. Parker was his “old lady.” Based on this circumstantial evidence, we affirm the district court’s finding that the government established a foundation for the conversation. Once the government established this foundation, it became the province of the jury to decide whether Mr. Parker was indeed the man on the phone and whether he made the threats; as the conversation was relevant to this determination, it was properly admissible under Fed.R.Evid. 401. Accordingly, we reject Mr. Parker’s argument.

Mrs. Parker argues that the evidence was insufficient to support her conviction. Because she failed to move for a judgment of acquittal at the close of the evidence, we review only for plain error.
See United States v. McCarty,

Finally, Mrs. Parker alleges various errors in her sentencing and the court’s
*329
adoption of the Presentence Report (“PSR”). We review the trial court’s legal interpretation and application of sentencing guidelines
de novo
and its factual findings in connection with sentencing for clear error.
See United States v. Ismoila,
Mrs. Parker first argues that the court erred in considering the confession she made to Agent Jenkins in deciding her sentence. We reject this argument because the statement was admissible and was introduced at trial.
See United States v. Collins,
Mrs. Parker next alleges that the district court erred in crediting the part of the PSR that stated that Mrs. Parker took $8,000 from Peggy Kelly’s sister in the bathroom of a Wendy’s restaurant for obtaining benefits. We reject her argument because she failed to present any rebuttal evidence to support her argument. Moreover, the jury convicted Mrs. Parker on one count of taking money from Peggy Kelly’s sister and therefore, the court only adopted what the jury had previously determined.
Mrs. Parker alleges that the victim impact portion of the PSR is deficient because it overstates the victim impact. She argues that the only victims in this ease were the individuals from whom she took money and only their payments to her should be considered in affixing the amount of the loss. The PSR identified the SSA as the victim, stated that the total fraudulent claims amounted to $69,673.85, and broke down the claims by each individual, which the district court as being both accurate and reliable. Loss calculations will be affirmed so long as they reasonably estimate the loss using reasonably available information.
See
U.S.S.G. § 2F1.1, cmt. 8;
United States v. Chappell,
Mrs. Parker also argues that the district court erred in increasing her offense level under U.S.S.G. § 2B3.2 based on its finding that her offense involved threats of physical injury and property destruction.

A conspirator may be held liable for the substantive offenses of a eoconspirator when the acts are reasonably foreseeable and are done in furtherance of the conspiracy, even where the first conspirator lacked knowledge of or participation in the acts.
See Pinkerton v. United States,
Mrs. Parker argues that the district court erred in increasing her offense level pursuant to § 3Bl.l(e) of the Guidelines for her leadership role. We review this sentence enhancement only for clear error,
see United States v. Narvaez,
Finally, Mrs. Parker argues that the court erred in fading to consider her medical condition and her financial circumstances in imposing her sentence and ordering her to pay restitution, citing U.S.S.G. § 5H1.4 and § 5E1.2. We reject this contention because the district court considered her medical condition and financial circumstances before imposing the sentence and it explicitly declined to reduce her sentence.
See United States v. Winters,

The convictions of Joann Parker and Ralph Parker are AFFIRMED and the sentence of Joann Parker is AFFIRMED.
Notes
. SSI benefits are means-based benefits for needy elderly, blind, and disabled persons. An applicant for SSI first fills out an application for benefits at a local SSA office. If the initial application is denied, then the applicant may reapply. After the application has been denied twice, an applicant may appeal to the SSA Office of Hearing and Appeals, where an ALJ will review the file and, if necessary, order a hearing. The ALJ will issue a written opinion granting or denying SSI benefits, a copy of which is mailed in a letter to the applicant. The ALJ also may determine that the disability began at some prior point in time and order a lump-sum back payment.
. 18 U.S.C. § 201 provides in relevant part:
(b) Whoever—
*326 (2) being a public official or person selected to be a public official, directly or indirectly, corruptly demands, seeks, receives, accepts, or agrees to receive or accept anything of value personally or for any other person or entity, in return for:
(C) being induced to do or omit any act in violation of the official duty of such official or person.
shall be fined under this title or not more than three times the monetary equivalent of the thing of value, whichever is greater, or imprisoned for not more than fifteen years, or both, and may be disqualified from holding any office of honor, trust, or profit under the United States.
Id.
. Even assuming that the prejudicial effect of this statement substantially outweighed its probative value, see Fed.R.Evid 403, and that the district court erred in admitting it, such error was harmless because Simmons herself repeated this information in her testimony and the government played recorded tapes of those conversations to the jury.
See United States v. Gomez,
. Violation of § 201(b)(2)(C) is normally punishable under U.S.S.G. § 2C1.1, but if the offense involved a threat of physical injury or. destruction, U.S.S.G. § 2B3.2 is instead applied.
