McCormick’s “Explicit Quid Pro Quo” Is Triggered Only by True Campaign Contributions — and Secrecy/Non-Reporting Supports Treating “Campaign-Debt” Cash as Ordinary Bribes

1. Introduction

In United States v. Perez-Otero (1st Cir. May 15, 2026), the First Circuit affirmed the convictions and sentences of Ángel Pérez-Otero, former mayor of Guaynabo, Puerto Rico, following a six-day jury trial. The government’s core theory was that Pérez used mayoral influence over municipal contracting to steer and preserve public contracts for contractor Oscar Santamaría-Torres (Island Builders) in exchange for cash payments delivered covertly.

Pérez challenged nearly every stage of the proceedings: sufficiency of the evidence (including a McCormick v. United States theory that the payments were campaign contributions requiring an “explicit” quid pro quo), indictment validity, variance, jury instructions (including an entrapment instruction not requested), jury impartiality in light of publicity and juror social media activity, and both procedural and substantive reasonableness of the sentences (including Guideline enhancements and disparity arguments).

2. Summary of the Opinion

The First Circuit affirmed across the board. Key holdings:

  • Sufficiency: A rational jury could find the payments were not campaign contributions; and independently could find a quid pro quo and “official acts” supported by testimony and circumstantial evidence.
  • Indictment: No defect because the indictment alleged cash bribes—not campaign contributions—so McCormick v. United States did not require pleading an explicit quid pro quo.
  • Variance: Argument failed (unpreserved; no plain-error development), and in any event no notice prejudice given defendant’s pretrial motion and trial strategy.
  • Jury instruction/comment: Even assuming the trial judge commented on the evidence, Pérez failed to show prejudice.
  • Entrapment instruction: No plain error; defendant neither requested it nor carried a production burden on inducement.
  • Impartial jury: No abuse of discretion in addressing publicity, admitting photos, or declining additional voir dire after removing two jurors.
  • Sentencing: Guideline challenges were waived/unsupported or meritless; disparity arguments failed because comparators involved guilty pleas and cooperation.

3. Analysis

3.1. Precedents Cited

A. Campaign contributions, quid pro quo, and “official acts”

  • McCormick v. United States: The court treated McCormick’s “explicit promise” rule as limited to cases where the “property” is a political campaign contribution. Consistent with McCormick’s concern about criminalizing routine campaign finance, the panel emphasized the threshold question: were these payments actually campaign contributions? The court held the record allowed a rational jury to say “no,” relying heavily on secrecy, use of cash-stuffed envelopes handed directly to Pérez, and non-reporting to election authorities.
  • United States v. McDonough: Cited for two critical propositions: (1) McCormick’s explicitness requirement applies only in the campaign-contribution context; and (2) bribery agreements are typically proven circumstantially (the panel also relied on McDonough’s approach to sentencing comparators, noting the importance of plea versus trial posture).
  • McDonnell v. United States. and United States v. Carrasco: Used to address Pérez’s “official act” argument. Even assuming an official-act requirement applied to the charged statutes in the way Pérez framed it, the record supported a finding that Pérez used his position to influence contracting decisions, fitting McDonnell’s conception of official action, including exerting pressure on other officials.
  • United States v. DeQuattro, United States v. McNair, and United States v. Turner: These cases supplied the evidentiary logic that concealment is powerful proof of corrupt intent and that quid pro quo is often inferred from timing, secrecy, and the parties’ conduct.
  • United States v. O'Donovan: Supported rejecting “lawful access/lobbying” characterizations where a reasonable jury could infer bribery from the same facts; also reiterated that sufficiency review considers all evidence admitted, even if arguably admitted erroneously.
  • United States v. Tanco-Baez and United States v. Lara: Set the sufficiency standard: evidence viewed in the prosecution’s favor; conviction stands if a rational juror could find guilt beyond a reasonable doubt.
  • United States v. Olbres and United States v. Cruz-Ramos: Reinforced the appellate posture: where competing inferences are plausible, the court accepts those supporting the verdict.
  • Rivera-Corraliza v. Morales: Invoked to criticize conclusory, uncited factual assertions—reflecting the court’s insistence that appellate arguments remain tethered to the record.

B. Bribes vs gratuities; timing of payment vs timing of agreement

  • United States v. Fernandez and United States v. Gracie: Used to frame the bribe/gratuity distinction: bribes require quid pro quo; gratuities reward past acts without a prior exchange agreement.
  • Snyder v. United States: Delivered the key modern formulation the panel applied: timing of the agreement controls, not timing of payment. This undercut Pérez’s argument that later payments necessarily became gratuities because one contract had already been awarded.
  • United States v. Cortés-Caban: Supported the holistic-evidence approach: even if one event preceded another, the jury may infer the payments related to future official acts or benefits.

C. Indictment sufficiency and facial validity

  • United States v. Savarese and United States v. Lopez-Matias: Anchored de novo review of indictment challenges.
  • United States v. Capozzi and United States v. Maceo: Reaffirmed the “valid on its face” principle: a legally returned indictment is enough to proceed to trial; courts do not test evidentiary sufficiency on a motion to dismiss.
  • United States v. Ngige and United States v. Guerrier: Emphasized that dismissal motions cannot be used to litigate the government’s proof; the indictment’s alleged facts are taken as true.
  • United States v. Cruzado-Laureano: Cited for the narrower point: a specific quid pro quo is necessary under § 1951 only when the payment is a political contribution—again reinforcing the opinion’s gating move.

D. Variance, preservation, and notice

  • United States v. Condron, United States v. Katana, United States v. Chan, and United States v. Dellosantos: Provided the variance framework: variance is different facts used to prove the same offense; reversal requires prejudice (often framed as lack of notice).
  • United States v. Tang: The court used Tang to dispose of the variance claim because Pérez failed to preserve it and failed to develop a plain-error argument on appeal.

E. Judicial comments, prejudice, and fair-trial framing

  • United States v. Rivera-Rodríguez, United States v. Ofray-Campos, and United States v. Hebshie: Supplied the prejudice standard for judicial intervention claims: the defendant bears the burden to show serious prejudice and a reasonable probability of a different result absent the error.
  • United States v. Raymundí-Hernández: Distinguished: Raymundí-Hernández involved conduct creating an appearance of anti-defense witness bias; here, the challenged comment was not shown to discredit defense witnesses or change the outcome.

F. Entrapment and plain error

  • Lestage v. Coloplast Corp. and Teixeira v. Town of Coventry ex rel. Przybyla: Stated the four-part plain-error test applied to the unrequested entrapment instruction claim.
  • United States v. Vasco and United States v. George: Central rule: if a defendant neither requests an instruction nor relies on that defense theory at trial, a judge’s failure to give it sua sponte is not plain error.
  • United States v. Medina: Reinforced that entrapment arguments first raised on appeal are disfavored; the panel cited Medina in rejecting Pérez’s attempt to pivot late.
  • United States v. Pérez-Rodríguez, United States v. Teleguz, United States v. Hinkel, Jacobson v. United States, and United States v. Rodriguez: Framed entrapment’s two prongs—inducement and lack of predisposition—and the defendant’s modest burden of production. The panel found Pérez failed at the inducement step on this record.

G. Publicity, voir dire discretion, and juror bias

  • United States v. Carbone and United States v. Papantoniadis: Confirmed abuse-of-discretion review for continuances and evidentiary admission/exclusion.
  • United States v. Orlando-Figueroa and United States v. Medina: Required showing that the trial setting was inherently prejudicial—not merely that jurors could have seen media coverage.
  • United States v. Symonevich: Reinforced that evidence is not “unfairly prejudicial” simply because it is damaging.
  • Skilling v. United States: Underlined deference to trial courts on pretrial publicity and that voir dire need not eliminate every potentially biased juror if the seated jury is fair.
  • United States v. Zimny: Provided the standard of review (abuse of discretion) for voir dire adequacy.
  • United States v. Tsarnaev and Mu'Min v. Virginia: Clarified there is no blanket requirement to ask each juror what they consumed in the media; the duty is to conduct a process allowing the judge to assess impartiality.
  • Rodríguez v. Municipality of San Juan: Used to fault the lack of record citations and clear presentation of the jury-bias claims on appeal.

H. Sentencing: Guidelines, disparities, and waiver

  • United States v. Berroa and United States v. Bruno-Campos: Set the review standards: clear error for facts, de novo for Guideline interpretation, abuse of discretion for substantive reasonableness.
  • United States v. Arshad: Provided support for treating multiple payments as multiple bribes where they relate to multiple actions (relevant to § 2C1.1(b)(1)).
  • United States v. Rodríguez-Lozada: Reinforced that plea defendants are not valid disparity comparators to a defendant sentenced after trial.
  • United States v. González-Barbosa: Supplied the comparator requirement: without appropriate comparators, disparity claims fail.
  • United States v. Zannino: A recurring tool in the opinion: undeveloped arguments are treated as waived.

3.2. Legal Reasoning

A. The court’s “threshold characterization” move under McCormick

The opinion’s most practically significant reasoning is its sequencing: before debating whether a quid pro quo was “explicit” under McCormick v. United States, the court asked whether the jury could find the payments were campaign contributions at all. The panel held the record supported a “not a contribution” inference based on (i) the secret handoffs directly to Pérez, (ii) contrast with how Santamaría made acknowledged campaign contributions (cash to the campaign director in others’ names), (iii) the absence of disclosure to the Office of the Electoral Comptroller despite Pérez’s knowledge of reporting requirements, and (iv) testimony suggesting payments continued after the campaign “debt” was supposedly paid.

B. Quid pro quo: direct testimony plus circumstantial corroboration

The court rejected the idea that there was “no evidence” of quid pro quo: Santamaría testified he made illegal payments “in order to get contracts and . . . benefits,” agreed they were “bribes,” and the circumstances—timing of contract discussions, secrecy, evidence of assistance with a specific road project and its asphalt component, and Pérez’s statement that Island Builders could “have one” of coming contracts the same day of a covert payment—permitted an inference of exchange.

C. Bribe vs gratuity: agreement timing governs

Addressing the claim that later payments were mere gratuities because one contract had already been awarded, the panel relied on Snyder v. United States to emphasize that the critical question is when the corrupt agreement was formed, not when money changed hands. It also reasoned the jury could view the later payments as tied to other anticipated official actions (including future contracts), not solely the prior award.

D. Indictment and variance: the difference between pleading and proof

The indictment challenge failed because the charging document alleged cash bribes (not campaign contributions), so it did not trigger McCormick’s explicitness pleading premise. The variance claim failed procedurally (no preservation; no plain-error development), and substantively because notice prejudice was implausible given Pérez’s own pretrial motion and trial opening that framed the payments as political contributions—showing the defense was not “in the dark” about the theory.

E. Jury instruction/comment and entrapment: prejudice and production burdens

The panel was willing to acknowledge the judge’s statement could be read as commenting on the evidence. But it treated the issue as outcome-sensitive: without a showing of a reasonable probability of a different result, reversal was unavailable. Entrapment likewise failed because the defendant neither requested the instruction nor produced evidence of improper inducement beyond the existence of the FBI operation and Santamaría’s inquiries.

F. Jury impartiality: deference to trial court management

On pretrial publicity and juror social media activity, the court applied strong deference (consistent with Skilling v. United States and United States v. Tsarnaev). Removing two jurors “out of an abundance of caution” and confirming remaining jurors’ ability to be impartial sufficed absent concrete evidence of taint.

G. Sentencing: waiver discipline and comparator rigor

The opinion is also a reminder that Guideline challenges must meaningfully engage application notes and the district court’s findings. The § 2C1.1(b)(1) argument was deemed waived for failure to grapple with the “single action” limitation in the commentary and the finding of multiple influenced actions. The disparity argument failed because the proposed comparators involved guilty pleas and cooperation, which are materially different sentencing postures.

3.3. Impact

  • Campaign-finance framing will not automatically import McCormick: Defendants cannot rely on labels like “campaign debt” to force an “explicit quid pro quo” requirement; courts will focus on objective indicia—secrecy, reporting, routing, and continuation after “debt” satisfaction—to determine whether the payment is truly a campaign contribution.
  • Operational guidance for prosecutors: Charging “cash payments” (not “campaign contributions”) can avoid pleading disputes under McCormick, while still allowing the government to address campaign-related testimony at trial—especially where the record supports non-contribution characterization.
  • Variance claims need preservation and plain-error briefing: The decision underscores that even colorable variance concerns can be lost through procedural default and failure to argue plain error.
  • Entrapment is not a post-trial pivot: Absent trial reliance and evidence of inducement, appellate courts will not treat omission of an entrapment instruction as plain error.
  • Sentencing disparity arguments require real comparators: National averages and plea-case examples will not typically show “unwarranted disparity” for a defendant who went to trial.

4. Complex Concepts Simplified

  • “Quid pro quo”: A corrupt exchange—money (or something valuable) given for an official’s action or influence.
  • McCormick’s “explicit promise” rule: A heightened proof requirement for extortion under color of official right when the alleged payment is a campaign contribution, meant to avoid criminalizing routine campaign fundraising.
  • “Official act” (McDonnell): Not just general goodwill; it is a formal government decision/action (or pressuring others to take one), such as influencing a contracting decision.
  • Bribe vs gratuity: A bribe involves a prior agreement to exchange value for influence; a gratuity is a reward given after the fact without that exchange agreement. Under Snyder v. United States, timing of the agreement matters more than timing of payment.
  • Variance: When the government proves the charged offense using facts materially different from those alleged; reversal requires prejudice (often lack of notice).
  • Plain error: A demanding standard on unpreserved issues: clear/obvious error that affected substantial rights and the fairness/integrity of proceedings.
  • Entrapment: A defense requiring both government inducement and lack of predisposition to commit the crime before government contact.

5. Conclusion

United States v. Perez-Otero reinforces a practical rule with significant consequences in public-corruption prosecutions: McCormick’s “explicit quid pro quo” requirement does not come into play unless the payment is actually a campaign contribution, and juries may reject “campaign-debt” characterizations where the surrounding facts—secrecy, non-reporting, and continuing payments—fit ordinary bribery. The opinion also highlights appellate gatekeeping: undeveloped arguments are waived, unpreserved claims require plain-error analysis, and sentencing-disparity arguments demand truly comparable defendants.
