Defendant Sanford I. Atkin, an attorney, appeals Ms conviction and sentence on multiple charges arising out of Ms acceptance of $550,000 from Reuben Sturman, a defendant in a federal tax prosecution. In the indictment, the government alleged, among other things, that Atkin had obtained the money from Sturman by falsely representing that he, Atkin, would bribe the UMted States District Judge presiding over Sturman’s criminal case. Atkin never did bribe the judge, and he now challenges the sufficiency of the evidence to support Ms convictions on two counts of obstruction of justice. Atkin also challenges the district court’s demal, without an evidentiary hearing, of his motion to suppress, as well as the district court’s decision to enhance Ms sentence for obstruction of justice and money laundering under U.S.S.G. § 3B1.3 on the basis that Atkin used Ms skills as an attorney to significantly further or conceal those offenses. For the reasons to follow, we AFFIRM.

On November 4, 1994, a federal grand jury sitting in the Northern District of OMo returned a 30-count indictment charging Sanford Atkin, a Cleveland attorney, with various offenses including two counts of obstruction of justice, in violation of 18 U.S.C. § 1503; seven counts of interstate transportation of property obtained by fraud, m violation of 18 U.S.C. § 2314; 11 counts of engaging in a monetary transaction in criminally derived property, in violation of 18 U.S.C. § 1957; one count of witness tampering, in violation of 18 U.S.C. § 1512; four counts of income tax evasion, in violation of 26 U.S.C. § 7201; four counts of filing false tax returns, in violation of 26 U.S.C. § 7206; and a final count wMch sought criminal forfeiture of $230,-202, pursuant to 18 U.S.C. § 982, based on the involvement of the funds in Atkin’s violation of 18 U.S.C. § 1957. The charges arose out of Atkrn’s acceptance of large sums of money from -Reuben Sturman, a world-wide distributor of “adult” materials who was a defendant in a federal tax evasion case in Cleveland, Ohio. Atkin ultimately accepted a total of $550,000 from Sturman under the pretense that Atkin would give the money to the UMted States District Judge to whom the tax evasion case was assigned.
Atkin did not represent Reuben Sturman in the tax evasion case; Sturman had retained other counsel who had successfully represented him in a number of obscemty prosecutions. Instead, Atkin’s oMy official role in the tax evasion case consisted of serving as local counsel for Sturman’s son David, who was also a defendant in the ease. 1 However, Atkin performed little work on behalf of David Sturman who, like Ms father, had other counsel. When the case went to trial in September, 1989, AtMn did not participate.
At the conclusion of a two-month trial on November 17, 1989, the jury in the tax evasion case reached a verdict finding both Reuben and David Sturman guilty on all charges. Reuben Sturman, who had apparently predicted such an outcome, attempted to ensure that he would remain free on bond pending sentencing and an appeal. Believing that Atkin was a close friend of the district judge presiding over the case, Sturman sought At-kin’s assistance in bribing the judge to rule in Sturman’s favor on the bond issue. Atkin agreed to help, and between November 6, 1989 and January 11, 1990, he accepted a total of $300,000 from Sturman for the purpose of bribing the district judge. Unbeknownst to Sturman, Atkin did not in fact use Sturman’s money to bribe the district judge, although the judge did, coincidentally, allow Sturman to remain free on bond pending sentencing and appeal. The district judge sentenced Sturman to 10 years impris *368 onment. Sturman’s appeals did not succeed, and he ultimately began serving his sentence, which was to run concurrent with a second four-year sentence imposed after Sturman entered a guilty plea on separate obscenity charges brought in federal court in Las Vegas, Nevada.
Subsequently, Sturman again sought At-kin’s assistance in bribing the district judge to secure a ruling in Sturman’s favor in the tax evasion case, this time on a motion under Fed.R.Civ.P. 35 seeking a reduction of his 10-year sentence to three years. Atkin again agreed to help, and during May, 1992, Sturman made additional payments to Atkin totalling $250,000 for the purpose of bribing the judge to grant Sturman’s Rule 35 motion. However, although Atkin did at one point approach the district judge in chambers and attempt to engage him in a discussion of Sturman’s situation, the district judge refused to discuss the case. 2 Once again, Atkin kept all of Sturman’s money for himself. Sturman, through his trial counsel, subsequently filed three separate Rule 35 motions; not surprisingly, all three were denied. In December, 1992, only days after his third motion was denied, Sturman escaped from a federal prison. He was subsequently recaptured, and he and others associated with him ultimately cooperated in the government’s investigation of Atkin.
On June 21, 1995, the jury found Atkin guilty on 28 of the 29 counts in the indictment, acquitting him only of witness tampering. In a bifurcated proceeding, Atkin was also required to forfeit $230,202 worth of property, pursuant to Count 30 of the indictment, On September 14, 1995, the district court sentenced Atkin to 63 months imprisonment, three years of supervised release, and a fine of $12,500. Atkin filed this timely appeal.

A.
After his indictment, Atkin filed a motion to suppress evidence seized during searches of his office and residence, arguing that the affidavits relied upon in obtaining the search warrants contained material misstatements and omissions essential to a finding of probable cause. The district court denied the motion without conducting an evi-dentiary hearing, concluding that application of the totality of the circumstances test, as required by
Illinois v. Gates,
Franks
recognized a defendant’s right to challenge the sufficiency of an executed search warrant on the basis that “a false statement knowingly and intentionally, or with reckless disregard for the truth, was included by the affiant in the warrant affidavit, and ... the allegedly false statement is necessary to the finding of probable cause[.]”
if and only if (1) there is a substantial preliminary showing that specified portions of the affiant’s averments are deliberately or recklessly false and (2) a finding of *367 probable cause would not be supported by the remaining content of the affidavit when the allegedly false material is set to one side.
United States v. Campbell,
Atkin does not contend that the affidavits contained materially false affirmative statements, but rather that they omitted information crucial to evaluating the credibility of Sturman, Delgado, and others who provided information to the government.
3
Although material omissions are not immune from inquiry under
Franks,
we have recognized that an affidavit which omits potentially exculpatory information is less likely to present a question of impermissible official conduct than one which affirmatively includes false information.
United States v. Martin,
Here, we have little difficulty concluding that the district court was not required to conduct a
Franks
hearing. As in
Martin,
the defendant’s contention is basically that the affidavit failed to provide information which showed that the informants’ credibility could be questioned.
B.
Atkin argues that the evidence presented was insufficient to convict him of the
*366
two charges of obstruction of justice. When a defendant challenges his criminal conviction on the basis of insufficient evidence, we must determine “ ‘whether, after viewing the evidence in the light most favorable to the prosecution,
any
rational trier of fact could have found the essential elements of the crime beyond a reasonable doubt.’ ”
United States v. Wright,
Atkin appears to concede that the government established that Sturman transferred money to Atkin based on Atkin’s representations that he would use the money to influence the district judge. 4 However, At-kin’s challenge to the sufficiency of the evidence focuses primarily on one uncontroverted fact: that Atkin never bribed the district judge. Because he merely defrauded a criminal defendant and did not actually bribe the judge, Atkin argues, he is not subject to conviction for violation of 18 U.S.C. § 1503. Section 1503 provides as follows:
Whoever corruptly, or by threats or force, or by any threatening letter or communication, endeavors to influence, intimidate, or impede any grand or petit juror, or officer in or of any court of the United States, or officer who may be serving at any examination or other proceeding before any United States commissioner or other committing magistrate, in the discharge of his duty, or injures any such grand or petit juror in his person or property on account of any verdict or indictment assented to by him, or on account of his being or having been such juror, or injures any such officer, commissioner, or other committing magistrate in his person or property on account of the performance of his official duties, or corruptly or by threats or force, or by any threatening letter or communication, influences, obstructs, or impedes, or endeavors to influence, obstruct, or impede, the due administration of justice, shall be fined not more than $5,000 or imprisoned not more than five years, or both.
Atkin was charged and convicted under the third clause of this section, known as the “omnibus clause,” which applies to one who “corruptly ... influences, obstructs, or impedes, or endeavors to influence, obstruct, or impede, the due administration of justice[.]”
United States v. Bashaw,
*365 Atkin’s principal arguments in support of reversal address his lack of success in influencing the district judge. Because the evidence showed that the district judge rebuffed Atkin’s only effort to engage in an ex parte discussion of Sturman’s case, Atkin argues that the government failed to show that he was attempting to influence the judge, and similarly failed to show that any endeavor was reasonably likely to succeed. However, this argument overlooks other key evidence of Atkin’s intent, namely, Reuben Stunnan’s testimony that Atkin promised that Stur-man’s money would find its way to the district judge, as well as Sturman’s testimony that Atkin agreed to approach the district judge to obtain a reduced sentence for Stur-man. Atkin’s lack of success is simply not controlling. Had Atkin succeeded in influencing the judge as promised, an obstruction of justice would have resulted.
Although this circuit has not yet determined whether participation in a scheme to defraud which has the potential for interfering with pending judicial proceeding constitutes a violation of § 1503, other circuits have resolved this question in the affirmative.
United States v. Machi,
Finding the reasoning of these cases to be sound, we now adopt it, and conclude that it was foreseeable that Sturman would act or fail to act in reliance on the false promise of a bribe, resulting in an obstruction of the due course of the underlying judicial proceeding. If nothing else, Atkin’s act of accepting money from Sturman under the pretense of making a bribe, which was disclosed to others by Sturman, caused a thorough investigation of a federal judge’s finances and could foresee-ably have led to his recusal from the Stur-man case. Because we think Atkin’s actions had the natural and probable effect of interfering with or influencing the due administration of justice, we conclude that the evidence was sufficient to support his convictions for violation of § 1503.
C.'
U.S.S.G. § 3B1.3 provides that an offense level may be increased by two levels “[i]f the defendant ... used a special skill, in a manner that significantly facilitated the commission or concealment of the offense[.]” The application notes to this section define a “special skill” as
a skill not possessed by members of the general public and usually requiring substantial education, training or licensing. Examples would include pilots, lawyers, doctors, accountants, chemists, and demolition experts.
U.S.S.G. § 3B1.3, comment, (n.2) (emphasis supplied). Atkin argues that the district court erred in enhancing his sentence on Counts 1 through 9 based on a finding that he had used his skill as a lawyer to facilitate commission or concealment of the offense. We review a district court’s factual finding regarding application of § 3B1.3 for clear error.
United States v. Williams,
Application of the enhancement under § 3B1.3 for use of a special skill requires only proof that the defendant’s use of
*364
that skill makes it significantly “easier” for him to commit or conceal the crime.
United States v. Young,
We conclude that the district court’s factual findings are not clearly erroneous, and that the district court properly applied § 3B1.3. Although, as we have already noted in Part II.B. above, Atkin was unsuccessful in getting the district judge to engage in an ex parte discussion of Sturman’s case, the ostensible normalcy of his visit to chambers could well have precluded further inquiry from the district judge or any other person who might have been suspicious regarding Atkin’s entry into chambers. The evidence strongly indicates that Atkin was well aware that he could use his position and skills as an attorney to conceal the true nature of his actions, and the evidence further supports a finding that he did precisely that. In November, 1991 Atkin sent a bogus letter to Reuben Sturman purporting to offer his services in pursuit of a claim of ineffective assistance of counsel. In the letter, Atkin stated that “[m]y fee to research and develop that will be $250,000.” 5 Although Atkin ultimately accepted a total of $550,000 from Reuben Sturman, he never filed any pleading, motion, or brief on the latter’s behalf in any court, nor did he ever make any official court appearance, apart from the ex parte visit to the district judge on behalf of Reuben Sturman.
We also note, as did the district court, that Atkin used his trust account to conceal his crimes. In depositing funds received from Sturman in the trust account, Atkin knew that the funds might take on the appearance of being legitimate.
See United States v. White,
Ill
For the foregoing reasons, we AFFIRM.
Notes
. David Sturman testified at trial that his father had instructed him to hire Atkin as local counsel because Atkin was "close” to the district judge and it would be beneficial to have Atkin serve on the case.
. At trial, the district judge testified that Atkin approached him in chambers, asking "can anything be done for Mr. Sturman." According to the district judge, he abruptly responded that he "[did not] rule on things that aren't before me.” Atkin dropped the matter and left chambers. The district judge testified that he was subsequently investigated by both the Federal Bureau of Investigation and Internal Revenue Service. He was not charged with any wrongdoing.
. In his motion filed below, Atkin did argue that the affidavits not only omitted material information but also contained false affirmative statements, including a statement that Atkin accepted his first payment from Sturman after the jury had already returned guilty verdicts (this was inaccurate; the first $100,000 payment was made several days before the jury concluded its deliberations), and a statement that Sturman never paid Atkin legal fees (Sturman apparently agreed to pay one-half of Atkin’s $25,000 fee to act as local counsel for David Sturman; David Sturman was to pay the other one-half). On appeal, however, Atkin has abandoned any argument that these statements had any bearing on a finding of probable cause; instead, he focuses only on the alleged omissions discussed herein.
. In his brief, Atkin concedes that the evidence at trial “may have established" that he received money from Sturman; that Atkin claimed he could influence the district judge; and that Stur-man transferred money to Atkin based on those representations. Appellant’s Brief at 11.
. At trial, Sturman testified that Atkin’s letter was "nonsense.” He also testified that he had no interest in pursuing an ineffective assistance of counsel claim against his trial attorney. Clearly, the jury did not believe that Sturman had paid Atkin $250,000 for the purpose of preparing such a claim.
