Donald Trump says Oprah Winfrey is no longer the person he knew in previous decades.
The iconic talk show host supports Kamala Harris' 2024 candidacy for president and live streamed an event last week with the vice president.
Trump said the person he watched speak with Harris on Friday 'isn't the real Oprah.'
Winfrey's event with Harris sought to ride the wave of support the VP has enjoyed since entering the race after President Joe Biden ended his reelection bid on July 21.

Other celebrities like Meryl Streep and Jennifer Lopez participated in the 90-minute event from Michigan, one of the seven battleground states key to winning in November's election.
Trump participated in a few interviews with Winfrey over the years and noted that in his Truth Social post on Saturday where he went after the talk show host.
'A long time ago, Oprah Winfrey asked me to do her last Network Television Show. The final week of her show was a big deal, and it was my honor, with my family, to do it,' he wrote of the registered independent voters.
'When I watched her interview yesterday with a woman who is destroying, through her complete and total incompetence, America, I couldn't help but think this isn't the real Oprah,' he said, changing his tune with: '[T]his isn't a person that wants millions of people, from prisons and mental institutions, and terrorists, drug dealers, and human traffickers, from all over the World, pouring into our Country.'
Ahead of Thursday's United for America event, Winfrey said she was hoping to get Americans excited about voting this cycle.

Trump, however, claimed in his Truth Social ramblings that Harris is not 'mentally fit' to serve at the helm of the Oval Office.
'Kamala looked really foolish, couldn't answer the simplest of questions on Inflation, the Cost of Goods, or our very porous and dangerous Border - No leader there, and Oprah just wanted to crawl under a table!' Trump continued.
'Comrade Kamala Harris is mentally unfit to be President. She knows it, and so does everyone else!'
