President-elect Donald Trump has named billionaire activist investor Carl Icahn as special adviser to the president on issues relating to regulatory reform, according to a statement from the Trump-Pence Transition Team.

“Carl was with me from the beginning and with his being one of the world’s great businessmen, that was something I truly appreciated,” Trump said in a prepared statement. “He is not only a brilliant negotiator, but also someone who is innately able to predict the future especially having to do with finances and economies. His help on the strangling regulations that our country is faced with will be invaluable.”
