Some 15 percent of Americans are enrolled in Medicare Part D, which covers outpatient prescription drug costs for older adults and other qualifying individuals, providing nearly $140 billion a year in support to about 50 million people. But the program is administered by the Centers for Medicare and Medicare Services—which President-elect Donald Trump has nominated celebrity physician Mehmet Oz to lead. It’s questionable how a man infamous for promoting questionable supplements, who has commented that there’s no right to health for people who can’t afford it, will help lead and provide government health insurance in the United States.
