He drove up to her property in Montecito, California, and handed the letter to a security guard on Thursday, March 25.
The 76-year-old, who made the 1,000-mile trip from his house in Rosarito, Mexico, wants to tell his side of the story, it is claimed.
A source told The Sun: “Thomas delivered a letter to Oprah asking her to contact him so he could tell his side of the story.
“This was not a note to Meghan and Harry, it was meant for Oprah.
“Thomas watched the interview she did with them and feels he deserves a chance to have his say.”
Oprah lives just a mile away from Meghan, Harry and Archie.
The Duchess of Sussex and her dad have not spoken for four years.
During the interview with Oprah, Meghan discussed her strained relationship with her dad, saying “I grieve a lot”.
She told Oprah: “I mean, I’ve lost my father. I lost a baby. I nearly lost my name. I mean, there’s the loss of identity. But I’m still standing, and my hope for people in the takeaway from this is to know that there’s another side.”
She said she found it difficult to describe his actions, adding: “I genuinely can’t imagine doing anything to intentionally cause pain to my child.”
Thomas leaked part of a letter that Mehgan had sent after her 2018 wedding to the press.
The Duchess of Sussex then won a court case against Associated Newspapers for publishing it, citing breach of copyright and misuse of her private information.
