The Wall Street Journal reported that U.K. regulators are investigating the professional relationship between Barclay’s Chief Executive Jes Staley and Jeffrey Epstein, the disgraced financier who died in jail last year.

According to the Journal, this investigation is Staley’s most recent brush with the authorities: in 2018, he was hit with penalties equal to about a quarter of his 2016 pay over his efforts to unmask a whistleblower, which U.K. regulators called a “serious error of judgment.” Staley is a U.S. citizens so U.S. authorities also fined him over the episode.
