A Citigroup executive who joined the bank’s wealth management division in a top position four months ago is leaving, raising questions about closely watched turnaround efforts to revive the $540 billion wealth business under new leadership. Don Plaus was named head of North America for Citi private bank earlier this year and started on April 1. Citi colleagues learned Friday that he had decided to leave, people familiar with the matter told Barron’s.
