MIT president L. Rafael Reif apologized Friday as the institution released a report outlining the $850,000 in donations the institution received from convicted sex offender Jeffrey Epstein between 2012 and 2017. The report investigates the ties between the late financier and two of MIT’s luminaries, professor Seth Lloyd and Media Lab director Joi Ito , who has since resigned.

The report revealed that Lloyd, along with “purposefully [failing] to inform MIT” about Epstein’s donations, told investigators he received a “personal gift of $60,000 from Epstein in or about 2005 or 2006 that was not known to, or recorded by, MIT” and put it in his personal bank account. Lloyd has been placed on paid administrative leave pending further investigation, MIT announced Friday.

Officials also announced steps MIT is taking to prevent another such donor relationship, which the school’s executive committee called “fundamentally incompatible with MIT’s values” in a statement Friday. The link to Epstein, which the report found Ito, Lloyd, and others took steps to keep under wraps, has previously led to calls for both Reif’s and Lloyd’s resignation. Most of the measures to prevent tainted donations are still works in progress, with concrete policies to be determined by a committee at a later date.

“I profoundly regret that decisions that sustained MIT’s ties to Jeffrey Epstein occurred on my watch and created so much pain and turmoil for the people of MIT; I feel a deep responsibility to repair what has been broken,” Reif said in a statement. “I also offer a heartfelt apology to the survivors of Jeffrey Epstein’s atrocious crimes, as well as to survivors of sexual assault and abuse in our own community.”

The report, prepared as part of an investigation by the prestigious law firm Goodwin Procter, appears to exonerate many members of MIT’s senior administration, including Reif, who signed a thank-you letter to Epstein in 2012. There was no evidence that Reif “had any knowledge that Epstein had a criminal record or was controversial in any way,” according to the report, which noted that Reif signed roughly 500 letters per year. Epstein’s donations included a total of $525,000 to support Ito and MIT’s Media Lab and $225,000 to support Lloyd.

“The report findings show that President Reif was not involved in the decision to accept these funds and that he had little knowledge of and insufficient information about Epstein’s background and crimes to understand the need to intervene in the process,” MIT’s executive committee said in its statement Friday. “The Executive Committee continues to have full confidence in his leadership of MIT.”

Epstein pleaded guilty in 2008 to a Florida state charge related to soliciting an underage girl for sex and was deemed a sex offender. He died last year, reportedly by suicide, while awaiting trial on federal sex trafficking charges.
