The prominent linguist and philosopher Noam Chomsky called it a “most valuable experience” to have maintained “regular contact” with Jeffrey Epstein, who by then had long been convicted of soliciting prostitution from a minor, according to emails released earlier in November this month by US lawmakers.

Perhaps the most telling of the Chomsky-related document in question was a letter of support for Epstein attributed to Chomsky with the salutation “to whom it may concern”. It is not dated, but it contains a typed signature with Chomsky’s name and citing his position as a University of Arizona laureate professor, a role he began in 2017, as first reported by the Massachusetts news outlet WBUR.

“I met Jeffrey Epstein half a dozen years ago,” read the letter of support from Chomsky that was reviewed by the Guardian after its Republican House oversight committee release. “We have been in regular contact since, with many long and often in-depth discussions about a very wide range of topics, including our own specialties and professional work, but a host of others where we have shared interests. It has been a most valuable experience for me.”

It is unclear whether Chomsky sent the letter to anyone. Nonetheless, it exalts Epstein for teaching Chomsky “about the intricacies of the global financial system” in a way “the business press and professional journals” had not been able to do. It boasted about how well connected Epstein was.

“Once, when we were discussing the Oslo agreements, Jeffrey picked up the phone and called the Norwegian diplomat who supervised them, leading to a lively interchange,” the letter read. The letter recounted how Epstein had arranged for Chomsky – a political activist, too – to meet with someone he had “studied carefully and written about”: the former Israeli prime minister Ehud Barak.

Epstein had – “with limited success” – aided efforts from Chomsky’s second wife, Valeria, to introduce him “to the world of jazz and its wonders”, the letter continued.

It concluded, “The impact of Jeffrey’s limitless curiosity, extensive knowledge, penetrating insights and thoughtful appraisals is only heightened by his easy informality, without a trace of pretentiousness. He quickly became a highly valued friend and regular source of intellectual exchange and stimulation.”

Another notable communication involving Chomsky and Epstein is a 2015 email in which the latter offers the former use of his residences in New York and New Mexico.

The emails don’t indicate whether Chomsky took advantage of the offer, whose particulars surfaced as certain officials are striving to investigate allegations of crimes by Epstein at a ranch compound he owned outside Santa Fe, New Mexico.
