Billionaire Icahn subpoenaed by US on biofuels dealing

New York

BILLIONAIRE investor Carl Icahn has been subpoenaed by the US Justice Department over his efforts to overhaul the US biofuels programme during his time as an unpaid adviser to President Donald Trump, his company revealed in Securities and Exchange Commission filings.

Mr Icahn's dual role as a presidential adviser and an investor with interests in multiple industries raised eyebrows earlier this year with Democratic lawmakers and government watchdogs.
