On August 9, 1984, a grand jury in the Northern District of Illinois returned a sixteen count indictment against David A. Ruzzano. Counts fifteen and sixteen, at issue here, charged Ruzzano with tax evasion in violation of 26 U.S.C. § 7201 in the amount of $813,000 and $236,000 for the years of 1979 and 1980 respectively. The indictment was the result of an investigation into Ruzzano’s participation in an oil swindle in which he allegedly promised investors substantial profits on investments in oil producing corporations that did not actually produce oil. At the time of the indictment, Ruzzano was not present in the United States, and his location abroad was unknown.
Ruzzano, who left the country in 1980, claims that he first learned of the criminal charges pending against him in 1985 when he entered the American Embassy in the Netherlands to renew his passport. At the request of the United States, Dutch authorities provisionally arrested Ruzzano, but they later released him on bond pending extradition. By the time U.S. Marshals had arrived to bring Ruzzano back to the United States, he had disappeared. Ruzzano’s whereabouts remained unknown until he was discovered in the French Caribbean on St. Martin in 1995. The French detained him for six months, but he was never arrested. After his release from French custody, Ruzzano’s whereabouts again became unknown to U.S. authorities until three years later when Ruzzano presented himself to the American Embassy in Lisbon, Portugal. He told the authorities there that he wanted to clear up the criminal charges pending against him. Eight months later — nearly fifteen years after he was indicted — Ruzzano was extradited to the United States.
Upon his return to the United States, Ruzzano entered an agreement with the government in which he pleaded guilty to two counts of tax evasion. In the plea agreement, Ruzzano acknowledged that he wilfully and knowingly attempted to evade the income tax due and owing to the United States of America by keeping improper records, failing to report income derived from a substantial number of cash transactions, and by failing to file income tax returns with the Internal Revenue Service for the calendar years of 1979 and 1980.
District Court Judge Suzanne B. Conlon conducted a guidelines-type sentencing hearing although none was required inasmuch as this was to be a pre-guidelines sentence. Before sentencing, both Ruzza-no and the government submitted their own versions of Ruzzano’s offense. Ruzza-no also submitted a position paper for sentencing in which he asked the court to consider the fact that he ultimately turned himself in. The position paper also took issue with a number of the government’s characterizations of his actions. In the position paper, Ruzzano claimed that he never intended to defraud anyone. Instead, he contended that his legal troubles were the result of “dreamy expectations and reckless bookkeeping.” The position paper also disputed the government’s characterization of Ruzzano’s initial departure from the United States as an attempt to evade the law. Although he did not deny that “he was a fugitive from justice *693 for many years,” Ruzzano maintained that he initially left the country not to evade the authorities but solely to avoid the effects of the recently enacted windfall profits tax. In support of this assertion, the position paper pointed out that no criminal charges were pending against Ruzzano when he left the country.
At sentencing, Ruzzano’s counsel repeated many of the same arguments made in the position paper. Ruzzano’s attorneys emphasized the fact that Ruzzano, while once a fugitive, did ultimately decide to turn himself in and accept responsibility for his actions. Counsel also asked the court to take into account certain mitigating factors including contriteness, exemplary military service, chronic health problems, and time spent in “horrifying conditions” in a Portuguese prison. In response, the government argued that Ruz-zano’s attempts to avoid apprehension should aggravate his sentence. Noting that he would be sentenced under the pre-guidelines sentencing regime in which defendants serve less of their sentence than under the guidelines, the government recommended that Ruzzano be sentenced to the maximum term of imprisonment — five years per count. The district court agreed. The court stated that the fact that Ruzzano ultimately turned himself in to the authorities some fifteen years after he was indicted was not enough to show acceptance of responsibility. Consistent with the government’s recommendation, the district court then imposed the maximum allowable sentence: five years for each count, the terms to run consecutively, for a total of ten years imprisonment.
Ruzzano raises three issues on appeal. First, he claims that the district judge should have recused herself pursuant to 28 U.S.C. §§ 455(a) and 455(b)(3). Next, Ruzzano contends that his counsel failed to provide effective assistance at sentencing. Lastly, he claims that the district court abused its discretion in sentencing by overlooking evidence of remorse, contrition, acceptance of responsibility, and other mitigating factors.
I. Analysis
A § Jp55 Claims
Ruzzano argues that Judge Conlon should have recused herself from his case pursuant to 28 U.S.C. §§ 455(a) and 455(b)(3). His claim, never presented to Judge Conlon and raised for the first time on appeal, is based on the fact that Judge Conlon served as an Assistant United States’ Attorney (AUSA) in the U.S. Attorney’s Office for the Northern District of Illinois at the same time that Ruzzano was indicted by a grand jury in that district. At the outset, we note that we do not know whether Judge Conlon played any role in or was even aware of Ruzzano’s indictment during her time in the U.S. Attorney’s Office. While it is undisputed that her name does not appear on any of the documents related to the case, Ruzzano argues that Judge Conlon may have provided assistance or expressed an opinion about his case to a fellow AUSA.
Ruzzano sent a Freedom of Information Act (FOIA) request to the Department of Justice asking for information relating to Judge Conlon’s involvement with his case, but he did not receive a response. Although the government’s failure to respond to the FOIA request does concern us, we find it highly unlikely that the U.S. Attorney’s Office keeps a record of every time one AUSA sticks his head into another AUSA’s office to ask her a question about a pending case. Almost certainly, the sole person who knows whether Judge Conlon may have expressed an opinion on the merits of the defendant’s case is Judge Conlon herself. Had Ruzzano raised this issue in the district court, we would now *694 have the benefit of Judge Conlon’s response.
1. Ruzzano’s § í55(a) Claim.
28 U.S.C. § 455(a) provides that a judge must disqualify herself “in any proceeding in which h[er] impartiality might reasonably be questioned.” In this circuit, appellate review of a judge’s failure to disqualify herself under § 455(a) may only be obtained by petitioning the appellate court for a writ of mandamus prior to trial.
See United States v. Horton,
“[i]t is a fundamental principle of appellate review that unless an error affects the substantial rights of the appellant, it is not a basis for reversal.... [I]f a judge proceeds in a case when there is (only) an appearance of impropriety in his doing so, the injury is to the judicial system as a whole and not to the substantial rights of the parties. The parties receive a fair trial, even though a reasonable member of the public might be in doubt as to its fairness, because of misleading appearances.” Once the proceedings in the district court are complete, the harm sought to be avoided by the requirement of recusal for appearance of impropriety has been done — -the public image of the judiciary has already been damaged.
United States v. Troxell,
However, in this case the issue is not Ruzzano’s failure to petition for a writ of mandamus, but rather his failure to raise the issue before the district court at all. Because a party waives his § 455(a) recusal argument by failing to petition for a writ of mandamus, it follows that he also waives it by failing altogether to raise it at the district court level.
See United States v. Franklin,
2. Ruzzano’s § 455(b)(3) Claim
Ruzzano next argues that the district judge erred by not disqualifying herself pursuant to 28 U.S.C. § 455(b)(3). Like his § 455(a) claim, Ruzzano did not request recusal in the district court under § 455(b)(3) and thus raises this issue for the first time on appeal. Our cases have not directly addressed the issue of whether we may review a § 455(b) claim raised for the first time on appeal where the appellant did not move for recusal below.
See United States v. Smith,
Section 455(b)(3) provides that a judge must recuse herself “[wjhere [s]he has served in governmental employment and in such capacity participated as counsel, adviser or material witness concerning the proceeding or expressed an opinion concerning the merits of the particular case in controversy.”
Id.
As applied to judges who were formerly AUSAs, § 455(b)(3) requires some level of actual participation in a case to trigger disqualification.
See Boyd,
In order to show plain error, Ruzzano must show that Judge Conlon’s participation in the disposition of the case was an obvious or clear error and that it affected his substantial rights.
See United States v. Olano,
B. Ineffective Assistance of Counsel Claim
Ruzzano next claims that he was denied effective assistance of counsel in violation of the Sixth Amendment because his counsel failed to move for recusal of the district judge and did not object to the government’s characterization of Ruzzano as a fleeing felon. Generally, we are reluctant to hear ineffective assistance of counsel claims on direct appeal.
See United States v. Hall,
Because we begin with a strong presumption that counsel’s conduct falls within the wide range of acceptable professional assistance,
see Long v. Krenke,
1. Failure to Move For Recusal of the District Judge Under § 155(a) or § 155(b)(3)
As one basis for his ineffective assistance of counsel claim, Ruzzano cites to his counsel’s failure to move for the recusal of the district judge. Because we do not know whether Judge Conlon played any role in Ruzzano’s indictment, or whether Ruzzano’s counsel ever investigated that possibility, it would be difficult to determine on direct appeal whether counsel’s performance fell below an objective standard of effective representation. It is unnecessary, however, for us to make such a determination because we are not required to make a finding as to the performance prong of the
Strickland
test before we examine the prejudice prong.
See United States v. Depoister,
Ruzzano’s attempt to show that he was prejudiced by counsel’s failure to move for the recusal of Judge Conlon falls short. In order to show prejudice, a defendant must show a reasonable probability that, if not for counsel’s unprofessional errors, the outcome of the proceeding would have been different.
See Strickland,
The prejudice inquiry revolves around the question of whether counsel’s deficient performance renders the proceeding fundamentally unfair.
See Foster v. Schomig,
2. Failure to Object to the Government’s Characterization of Ruzzano as a Fleeing Felon
Ruzzano also claims that he was denied effective assistance of counsel because the government erroneously portrayed him as a fleeing felon in the government’s version of the offense and at sentencing, and his counsel failed to object. Specifically, Ruzzano argues that his counsel erred by: (1) admitting at sentencing that Ruzzano had been a fugitive; and by (2) failing to object to the false impression given by the Pre Sentence Investigation Report (PSI) that Ruzzano “knowingly fled the United States to escape prosecution.” We disagree. First, it is clear that Ruzzano’s attorney did try and correct the government’s characterization of Ruzzano as a fugitive from justice. In defendant’s position paper for sentencing, Ruzzano’s counsel pointed out that Ruzza-no left the country well before he was indicted. It also maintained that Ruzzano did not know that he was under federal criminal investigation when he left the United States. According to the position paper, Ruzzano left the country not to avoid criminal charges but because newly enacted tax laws destroyed his business opportunities in the United States. The fact that the district court did not accept the interpretation of Ruzzano’s behavior urged by Ruzzano’s counsel does not give rise to an ineffective assistance of counsel claim.
Given the circumstances surrounding Ruzzano’s extradition, Ruzzano would not be able to show that counsel’s performance fell below an objectively reasonable standard even if his counsel had failed to object to the characterization of Ruzzano as a fleeing felon. As we have already noted, “[t]he
Strickland
test is ‘highly deferential to counsel, presuming reasonable judgment and declining to second guess strategic choices.’ ”

C. Sentencing Claims
Ruzzano’s last claim is that the district court abused its discretion by relying on erroneous information and failing to take mitigating factors into consideration during sentencing.
1
As we have repeatedly noted, our review of pre-guidelines sentences is extremely limited.
See United States v. Stevenson,
Lastly, Ruzzano claims that the district court erred in imposing his sentence because it failed to consider mitigating factors such as his remorse, acceptance of responsibility, bad health, and time spent in “horrifying conditions” in a Portuguese prison. Ruzzano’s argument ignores the fact that judges are entitled to determine what weight to give mitigating factors,
see United States v. Perez,
858
*699
F.2d 1272, 1276 (7th Cir.1988), and we will not upset such a determination absent evidence that the sentencing judge utterly failed to exercise discretion.
See United States v. Harris,
II. Conclusion
For the foregoing reasons, we AffiRM the sentence imposed by the district court.
Notes
. Ruzzano also argues that his sentence is unduly harsh because he would have received a lighter sentence under the sentencing guidelines. The appropriate punishment under the sentencing guidelines is not relevant here, however, because Ruzzano committed his crimes in 1979 and 1980 and the guidelines do not apply to offenses that occurred before November 1, 1987.
