Dr. Oz Canceled, Oprah Relationship, and New CMS Role

Dr. Mehmet Oz went from being a trusted face on daytime television to leading one of the most powerful health agencies in the United States. His journey through medical stardom, product endorsement controversies, and a failed Senate campaign has been anything but ordinary. Now, as the 17th Administrator of the Centers for Medicare & Medicaid Services, he oversees health coverage for more than 160 million Americans.

CMS Administrator: 17th · Americans covered: 160 million · Appointed: November 19, 2024

Six key facts, one pattern: Oz’s career accelerated from medicine to media to government, but each step brought new scrutiny.

Why did Dr. Oz get canceled?

Senate criticism on medical claims

Oz faced intense criticism from lawmakers. Senator Elizabeth Warren’s office noted that Oz had deep ties to health-care and pharmaceutical firms that could benefit from CMS decisions (Office of Senator Elizabeth Warren). During his TV show, he promoted hydroxychloroquine as a COVID-19 treatment (ABC News), a stance that later drew backlash from the medical community.

Editorial on pseudoscience

Oz also made statements suggesting support for spacing out childhood vaccines and expressed ambivalence about the discredited claim that vaccines cause autism (ABC News). While he later endorsed the MMR vaccine on his show, the earlier remarks fueled accusations of promoting pseudoscience.

Decline in viewership and end of The Dr. Oz Show

By 2022, the show had ended after 13 seasons. Oz moved on to political ambitions, but the reputation of trading in questionable health advice lingered. “The trade-off: medical credibility was sacrificed for entertainment ratings.”

The pattern: Oz’s television career ended under the weight of the same controversies that now follow him into government service.

Does Oprah still have a relationship with Dr. Oz?

Oprah’s role launching Dr. Oz

Oprah Winfrey first featured Oz on her show in 2004 and later helped produce his own program. No public collaboration has occurred since The Dr. Oz Show ended.

Public statements and distancing

In 2014, Winfrey defended Oz after Senate hearings but later expressed regret over some of his endorsements, according to published reports. No recent statements confirm ongoing ties.

Current professional ties

Neither party has announced any joint projects or business arrangements. The lack of public appearances together since 2022 suggests a professional separation.

The implication: Oprah’s distance from Oz marks a significant shift from the mentor-protégé relationship that launched his television career.

What happened to Dr. Oz?

Transition from TV to CMS

• Appointed CMS Administrator on November 19, 2024 (ABC News)
• Sworn in during April 2025 (Healthcare Dive)

Senatorial candidacy in Pennsylvania

Oz ran for the U.S. Senate in Pennsylvania in 2022 but lost (Yahoo News). It was his only political campaign before the CMS appointment.

Current role as federal administrator

At CMS, he oversees Medicare, Medicaid, CHIP, and the Health Insurance Marketplace (Centers for Medicare & Medicaid Services). He has vowed to reduce chronic disease, modernize the programs, and cut fraud (Healthcare Dive).

The catch: Oz now holds authority over the very health programs he once discussed as a television personality.

Does Dr. Oz actually have a medical degree?

Education and training

Oz is a physician and a board-certified cardiothoracic surgeon (ABC News). He earned his MD from the University of Pennsylvania, but the degree itself is not publicly disputed.

Board certification

He has been certified by the American Board of Thoracic Surgery. No allegations of misconduct have been sustained against his medical license.

Criticism of medical authority

Critics argue that Oz blurred the line between entertainment and medicine by promoting unproven treatments. The criticism does not challenge his credentials, only his use of them on television.

The pattern: While Oz’s medical credentials are genuine, his television persona created a credibility gap that has followed him into his federal role.

How many times was Dr. Oz married?

Marriage to Lisa Oz

Oz married Lisa Oz in 1985. The couple has remained together ever since, though their marriage has not been without media speculation.

Family background

They have four children together. Lisa Oz is an author and television producer who occasionally appeared on his show.

Public personal life

There are no records of other marriages. Oz’s personal life has remained relatively private compared to his public career.

Timeline: From TV doctor to CMS administrator

• 2022: Runs for U.S. Senate in Pennsylvania (loses) (Yahoo News)
• November 2024: Appointed CMS Administrator by President-elect Trump (ABC News)
• April 2025: Sworn in and completes first week as 17th Administrator (Centers for Medicare & Medicaid Services)

The pattern: Oz’s trajectory shows a rapid shift from television to politics to federal leadership in less than five years.

Clarity check: What’s confirmed, what’s still unclear

The implication: The confirmed facts about Oz’s career are well-documented, but significant gaps remain in understanding the full scope of his influence and potential conflicts.

Quotes that shaped the story

Oz would oversee Medicare, Medicaid, and Affordable Care Act coverage for 160 million Americans.

– Senator Elizabeth Warren, letter regarding Oz’s nomination (Office of Senator Elizabeth Warren)

focus on reducing chronic disease, modernizing Medicare and Medicaid, and targeting fraud, waste, and abuse.

– CMS press release, April 2025 (Centers for Medicare & Medicaid Services)

The pattern: The quotes reveal the tension between Oz’s critics and his own stated priorities as he steps into federal leadership.

For the 160 million Americans relying on Medicare, Medicaid, or the Marketplace, Dr. Oz’s tenure means a health leader with strong ties to the pharmaceutical industry and a record of promoting unproven treatments. The coming months will reveal whether his policy goals can overcome the controversies of his past.
