Dr. Mehmet Oz, nominated by former President Trump to lead the Centers for Medicare and Medicaid Services, is undergoing a confirmation hearing where he is expected to address concerns related to his ties to the health industry and allegations of underpaying Medicare taxes. Senators, including Elizabeth Warren, are pressing him to sever connections with pharmaceutical companies and other health sectors. During the live hearing, Dr. Oz will defend his record while responding to skepticism from lawmakers about his qualifications and potential conflicts of interest. As he aims to reassure the public about the future of Medicare and Medicaid, his nomination has stirred significant debate regarding the intersection of politics and healthcare.
