Investing.com -- JPMorgan Chase CEO Jamie Dimon has been asked by Senator Elizabeth Warren to clarify whether he lobbied the UK government against a proposed tax on bankers' bonuses based on advice from Jeffrey Epstein, according to a letter released by the Senate Banking Committee on Monday.

The request comes after documents released earlier this year by the U.S. Department of Justice renewed scrutiny of prominent policymakers and business leaders over their past interactions with the late convicted sex offender.

In her letter, Warren, the top Democrat on the Senate Banking Committee, said Congress and the public deserve a full accounting of any interactions involving JPMorgan, Dimon, and Epstein.

The inquiry follows a Financial Times report citing Justice Department emails showing that in 2009, then-UK Business Secretary Lord Peter Mandelson told Epstein that Dimon should "mildly threaten" then-Chancellor Alistair Darling over a proposed tax on bankers' bonuses.

Epstein was a JPMorgan client from 1998 until the bank terminated the relationship in 2013, several years after he pleaded guilty to prostitution-related charges. In 2023, JPMorgan agreed to pay approximately $290 million to settle a class-action lawsuit brought by Epstein's victims.

JPMorgan said in a statement to Reuters that Dimon never met or exchanged emails with Epstein and had no involvement in decisions related to Epstein's banking relationship. The bank said its position remains consistent with Dimon's 2023 deposition testimony.
