If confirmed to run the Centers for Medicare & Medicaid Services, television personality Dr. Mehmet Oz, President-elect Donald Trump's nominee, would oversee two large federal health insurance programs that cover about 2 in 5 Americans and greatly influence the nation's health care system.

Trump said Mehmet Oz would work closely with his health secretary pick, Robert F. Kennedy Jr., “to take on the illness industrial complex, and all the horrible chronic diseases left in its wake.”
