Passage: Flamboyant television financial expert Lee Gates is in the midst of the latest edition of his show, Money Monster. Less than 24 hours earlier, IBIS Clear Capital's stock inexplicably cratered, apparently due to a glitch in a trading algorithm, costing investors $800 million. Lee planned to have IBIS CEO Walt Camby appear for an interview about the crash, but Camby unexpectedly left for a business trip to Geneva.

Question: Who was Gates supposed to interview?
Walt Camby
