Larry Summers, the former U.S. Treasury secretary who has been dogged by his past friendship with Jeffrey Epstein, announced Wednesday that he will resign from teaching at Harvard University by the end of the current academic year, the university said.

Summers previously served as president of Harvard.

His resignation came as the university was conducting a review of emails and other documents detailing Summers’ connection to Epstein, which were released in recent months by the Department of Justice and Congress.

Summers has not been accused of wrongdoing in connection with Epstein. He will not teach or take on new advisees until his retirement is effective.

“In connection with the ongoing review by the University of documents related to Jeffrey Epstein that were recently released by the government, Harvard Kennedy School Dean Jeremy Weinstein has accepted Professor Lawrence H. Summers’ resignation from his leadership position as co-director of the Mossavar-Rahmani Center for Business and Government,” Harvard spokesman Jason Newton told CNBC in a statement on Wednesday.

“Professor Summers has announced that he will retire from his academic and faculty appointments at Harvard at the end of this academic year and will remain on leave until that time,” Newton said.

Summers’ resignation comes three months after he took a leave from Harvard, where he had been teaching classes, and after he resigned from the board of the artificial intelligence company OpenAI amid controversy over the release of emails between him and Epstein.

“I am deeply ashamed of my actions and recognize the pain they have caused. I take full responsibility for my misguided decision to continue communicating with Mr. Epstein,” Summers said in a statement obtained by CNBC in November.

His statement came on the heels of reports by the Harvard student newspaper, The Crimson, which detailed how Summers had sought guidance from Epstein while pursuing a romantic relationship with a woman.

In a statement to The Crimson on Wednesday, Summers called his decision to leave his professorship “difficult,” but also said he remained “grateful to the thousands of students and colleagues I have been privileged to teach and work with since coming to Harvard as a graduate student 50 years ago.”

“Free of formal responsibility, as President Emeritus and a retired professor, I look forward in time to engaging in research, analysis, and commentary on a range of global economic issues,” Summers told the newspaper.

Yale University said Wednesday that it has barred professor David Gelernter from teaching computer science classes, for now, as the university conducts a review of his contacts with Jeffrey Epstein, which included mentioning a Yale student for a potential project.

Gelernter’s extensive email correspondence with Epstein came to light after the release of files related to Epstein by the Department of Justice in late January.

Among those files is an October 2011 email to Epstein, in which Gelernter mentions a software project to be built.

“I have a perfect editoress in mind: Yale sr, worked at Vogue last summer, runs her own campus mag, art major, completely connected, v small goodlooking blonde,” Gelernter wrote.

The email was sent three years after Epstein pleaded guilty in Florida state court to soliciting an underage girl for prostitution. Epstein served 13 months in jail in that case.

The Yale Daily News reported Tuesday that Gelernter had been barred from teaching classes pending a review.

CNBC on Wednesday asked Yale about the status of Gelernter at the university and his contact with Epstein.

In an email statement to CNBC, a Yale spokeswoman said, “Yale is committed to excellence in the classroom and to fostering an environment in which all members of our community feel respected and valued.”

“Last week, leadership in the School of Engineering and Applied Science became aware of reports regarding communication between a professor and a party external to the Yale community; the professor later both acknowledged and defended this communication and the action he took in connection with the communication.”

“The university does not condone the action taken by the professor or his described manner of providing recommendations for his students.”

“The professor’s conduct is under review. Until the review is completed, the professor will not teach his class.”

Gelernter did not immediately respond to an emailed request for comment from CNBC.

Gelernter was seriously wounded in June 1993 when he opened a package containing an explosive device mailed to him by Ted Kaczynski, the so-called Unabomber. Gelernter lost the use of his right hand from the explosion.

Yale’s action against the professor comes nearly three months after former Harvard University President Larry Summers said he was stepping back from all public commitments because of fallout over the release of emails between him and Epstein.

The correspondence included Summers seeking guidance from Epstein about pursuing a romantic relationship with a woman he described as a mentee, the Harvard Crimson newspaper reported at the time.

Summers, who is also a former U.S. Treasury secretary, took a leave from teaching classes at Harvard, as well as from his post as the director of Mossavar-Rahmani Center for Business and Government at the…
