Donald Trump continues to announce key personnel for his incoming administration. The president-elect said he is nominating long-time TV talk show host Dr. Mehmet Oz to lead the Centers for Medicare and Medicaid Services. In a statement, Trump said Oz “will cut waste and fraud” within the country’s “most expensive government agency.” He also has chosen his transition co-chair Howard Lutnick to be commerce secretary. Lutnick, who was said to be in the running for Treasury secretary, is a billionaire who heads the brokerage and investment bank Cantor Fitzgerald.
