Howard Lutnick was appointed US commerce secretary by President Trump in 2025

A British man has told the BBC how he unearthed evidence indicating that his former employer, Howard Lutnick - now US commerce secretary - failed to disclose a business relationship with the paedophile financier, Jeffrey Epstein.

Simon Andriesz, previously a managing director at a Wall Street firm, discovered an email chain from 2018 in which Lutnick and Epstein had discussed the prospects of a start-up business they were both involved in.

Andriesz shared his findings - from the millions of released Epstein files - with US politicians on the influential House Oversight Committee, ahead of an appearance there by Lutnick in May.

Lutnick told the committee that, to the best of his knowledge, he had only learned this year that Epstein had been an investor in the firm. Speaking on his behalf, the US Commerce Department told us there was no evidence of wrongdoing.

Andriesz also discovered in the files that one of Lutnick's firms had made plans in 2013 to go into business with another figure linked to Epstein, the then-Prince Andrew, by commercially exploiting the contacts the former UK trade envoy had made.

"What it involved was a loan to Andrew Mountbatten-Windsor of £1m... to basically buy a prince," he tells File on 4 Investigates.

Searching 3.5 million documents

"I was completely shocked," says Andriesz, describing the moment when he discovered his own name in the Epstein files - a massive collection of documents, photos, video and emails relating to the notorious sex offender, released by the US government in the past year.
