Mehmet Oz

The former TV doctor made it through a tight vote in the Senate with only Republican support.

The celebrity doctor recently held investments worth tens of millions of dollars in health care, tech, and food companies which could pose significant conflicts of interest.

In announcing his pick, Trump said Oz will work closely with RFK Jr. "to take on the illness industrial complex." Oz, a celebrity physician, ran unsuccessfully for the U.S. Senate in 2022.

The seat, which flips from Republican to Democrat, was vacated by retiring GOP Sen. Pat Toomey.

Winfrey brought on Oz as a regular guest on The Oprah Winfrey Show for more than five seasons in the early 2000s, giving him his big breakthrough.

Pennsylvania, Georgia, Nevada and Arizona come into focus in final days. Plus: where things stand in seven other Senate contests.

Lt. Gov. John Fetterman, a Democrat, and former TV doctor Mehmet Oz, a Republican, faced off last night in the only debate in a tight race that will help determine control of the Senate.

Midterm elections are next month. NPR's Steve Inskeep speaks with Republican strategist Scott Jennings about the Senate races in two key states: Pennsylvania and Nevada.

Recent events are giving Democrats hope of retaining the 50-50 Senate, which they narrowly control with the vice president casting tie-breaking votes.

Pennsylvania Democrat John Fetterman's expected return to the campaign trail comes as issues such as abortion rights and gun violence have taken on a new intensity.
