Lead: On Thursday, Nov. 21, 2025, co-teachers at Harvard confronted students about the abrupt absence of former Harvard President Lawrence H. Summers after he stepped back from teaching amid scrutiny over his email exchanges with convicted sex offender Jeffrey E. Epstein. In one classroom, Harvard Kennedy School professor Jeffrey Liebman condemned Summers’ conduct as “inexcusable” and said he felt “pissed off” and “repulsed.” In another, professor Robert Lawrence read a prepared statement praising Summers’ contributions, prompting vocal student disagreement. Summers’ withdrawal followed mounting internal and external pressure and the university-anchored reporting that tied him to months of messages reviewed by Epstein.
Key Takeaways
- Lawrence H. Summers announced a leave from teaching this week after renewed scrutiny of his emails with Jeffrey E. Epstein, a convicted sex offender; the move was made public on Wednesday.
- Jeffrey Liebman, co-instructor of ECON 1420: “American Economic Policy,” told students Thursday he found Summers’ exchanges with Epstein “inexcusable,” using explicit language to convey personal outrage.
- Robert Lawrence, teaching Gen Ed 1120: “The Political Economy of Globalization,” delivered a concise, prewritten note saying Summers had stepped back and that the class would miss him, which drew immediate student pushback.
- The Harvard Crimson reported that over seven months Summers exchanged messages in which Epstein reviewed and commented on Summers’ text messages and described himself as Summers’ “wing man.”
- Lawmakers and public figures intensified pressure: President Donald Trump urged a Justice Department review, and Senator Elizabeth Warren (D–Mass.) publicly called for Summers’ removal or resignation from Harvard.
- Outside affiliations were quickly curtailed: Summers relinquished or was removed from roles that included an advisory position with OpenAI and contributions to The New York Times and Bloomberg.
- Students in both classrooms reacted in real time—some voiced anger, others offered quiet support—illustrating campus polarization as university leadership and outside actors press for responses.
Background
Lawrence H. Summers, a prominent economist and former Harvard president and Treasury official, co-taught courses this semester while maintaining a wide range of public roles and affiliations. The controversy stems from reporting that he exchanged emails with Jeffrey E. Epstein, who was convicted of sex offenses; those emails included iterations in which Epstein commented on Summers’ messages. That reporting, published by The Harvard Crimson, said the correspondence extended over roughly seven months and included language suggesting Epstein acted as an intermediary or “wing man” in some personal communications.
Summers initially told students he would continue teaching after the recent revelations, but as criticism intensified from students, faculty and elected officials, he abruptly announced a leave from classroom duties on Wednesday. The development unfolded against a broader national conversation about accountability for high-profile figures whose private conduct intersects with professional roles. Harvard, which faces institutional pressure to clarify how it evaluates faculty conduct, has become the focal point for debates over reputation, governance and due process.
Main Event
On Thursday morning in a Harvard Kennedy School lecture hall, Professor Jeffrey Liebman—who has been co-teaching ECON 1420: “American Economic Policy” with Summers—addressed students directly. According to multiple attendees, Liebman used unusually candid language, calling Summers’ exchanges with Epstein “inexcusable” and saying he was “pissed off” and “repulsed.” His remarks framed the absence as a moral and professional breach that demanded clear recognition in the classroom.
Hours earlier in Gen Ed 1120: “The Political Economy of Globalization,” Professor Robert Lawrence briefly informed students that Summers had stepped back from teaching and read a short, prepared note praising Summers’ insights and apologizing for the disruption. That scripted tone contrasted sharply with Liebman’s spontaneous denunciation and prompted audible student response, including one shouted objection—”No, we won’t”—that drew applause and laughter from peers.
Lawrence returned the class to its planned agenda, which included a guest appearance by former U.K. Prime Minister Tony Blair. Neither professor gave an extended institutional statement; both confined remarks to the classroom setting, leaving fuller administrative responses to Harvard leadership. The immediate effect was a campus atmosphere marked by confusion and emotion as students sought clarity about course continuity and the broader consequences for Harvard’s faculty governance.
Summers’ absence was notable because he had told students as recently as Monday that he intended to continue teaching. By Wednesday he announced a leave from public commitments as scrutiny intensified, and he either resigned from or was removed from several external roles, amplifying the sense of a rapid, cascading reputational fallout.
Analysis & Implications
The contrasting tones of Liebman and Lawrence illuminate an institutional dilemma: faculty must balance candid moral judgment with pedagogical continuity. Liebman’s blunt repudiation signals that some colleagues view the reported exchanges as crossing a line that undermines Summers’ suitability to teach, while Lawrence’s guarded language suggests concerns about due process, classroom stability and the optics of publicly condemning a colleague mid-semester.
Politically, calls from high-profile figures—President Trump urging a Justice Department review and Sen. Elizabeth Warren demanding institutional action—escalate pressure beyond campus. That external scrutiny increases the stakes for Harvard’s governing bodies, which must weigh reputational risk, legal exposure and academic norms when deciding whether to pursue disciplinary measures or await further investigation.
Economically, Summers’ rapid loss of outside affiliations (OpenAI advisory role, and contributions to major outlets like The New York Times and Bloomberg) illustrates how professional ties can dissolve quickly once allegations gain traction. For the university, donor and partnership relationships could be affected if stakeholders view institutional responses as insufficient or opaque. The episode may prompt Harvard and peer institutions to reassess conflict-of-interest safeguards and protocols for handling allegations involving senior faculty.
Looking ahead, the episode may have ripple effects on faculty recruitment and student trust. Prospective instructors and students watch how Harvard balances fairness with accountability; a perception of either cavalier tolerance or precipitous judgment could shape campus climate and governance reforms. Administrative transparency about investigatory steps and timeline will be central to restoring institutional confidence.
Comparison & Data
| Actor | Immediate Tone | Reported Action |
|---|---|---|
| Jeffrey Liebman (ECON 1420) | Direct condemnation | Called conduct “inexcusable” to students |
| Robert Lawrence (Gen Ed 1120) | Measured, scripted | Read statement praising Summers; class interruption |
| Students | Mixed (shouts, applause, quiet dissent) | Vocal classroom reactions |
| Lawmakers/Public | Demanding | Calls for investigation/resignation |
This table highlights how reactions vary across campus and beyond: faculty responses ranged from denunciation to restraint, students reacted emotionally in real time, and elected officials amplified calls for formal action. The pattern underscores the multi-layered pressures on universities when private conduct becomes public and politically salient.
Reactions & Quotes
In the ECON 1420 classroom, a faculty co-instructor condensed moral judgment into plain language before continuing the session.
“This conduct is inexcusable — I’m pissed off and repulsed by the exchanges that have come to light.”
Jeffrey Liebman, Harvard Kennedy School professor
In Gen Ed 1120, another professor opted for a brief, scripted acknowledgment that emphasized disruption and loss without casting explicit blame.
“As I’m sure you are all aware, Larry has decided to step down from his teaching responsibilities this semester. We will miss his insights and his wisdom.”
Robert Lawrence, Harvard Kennedy School professor
A student interruption captured the polarized classroom mood and illustrated how quickly institutional news can produce public contestation.
“No, we won’t.”

Unconfirmed
- The precise nature and intent of Summers’ described romantic interest, as reported by The Harvard Crimson, have not been independently corroborated outside that reporting.
- The full extent of Epstein’s editorial or advisory role in Summers’ private messages is based on Crimson reporting and has not been substantiated by a separate public investigation as of this writing.
- Whether the Justice Department will open a formal probe following public calls for review remains unresolved; no official DOJ announcement had been made as of Nov. 21, 2025.
Bottom Line
The episode crystallizes a difficult institutional moment for Harvard: a senior figure’s private communications with a convicted offender have produced swift reputational consequences, divergent reactions from colleagues in the classroom, and heightened demands from public officials. Immediate classroom responses—one blunt condemnation and one cautious tribute—reflect broader tensions between calling out alleged misconduct and preserving procedural norms.
How Harvard responds administratively and transparently in the coming days will shape campus trust and public perception. Key watchers—students, faculty, donors, and lawmakers—will judge whether the university’s process provides credible accountability without foreclosing due process. For students in affected courses, clarity on teaching continuity and investigatory timelines will be an urgent priority.
