James Stewart's family sees no relation between Donald Trump and "George Bailey."

Kelly Stewart Harcourt, the actor's daughter, made as much clear on Thursday in a letter she wrote to the editor of The New York Times. She responded after Natalie Harp likened the U.S. president to "Bailey" in It's a Wonderful Life in a speech made at the RNC on Aug. 24. Stewart Harcourt called the analogy to her father's film "the height of hypocrisy and dishonesty."

Natalie Harp's President Trump-It's a Wonderful Life speech

Harp, a bone cancer survivor who credits her recovery to treatment permitted by President Trump's 2018 "Right to Try" act, spoke on Day 1 of the RNC. Her speech explored Trump's deeds through the lens of It's a Wonderful Life and its "the world if you never existed" plot.

"When I failed the chemotherapies that were on the market, no one wanted me in their clinical trials," Harp recalled of her rare and terminal cancer. "They didn't give me the right to try experimental treatments, Mr. President. You did, and without you, I'd have died waiting for them to be approved."

"It's a wonderful life. You made America great again," Harp added at the end of the speech. But It's a Wonderful Life star James Stewart's descendants were none too pleased with Harp's comparison, which was upsettingly inaccurate in their view.

On Thursday, Kelly Harcout Stewart, the 69-year-old daughter of the late Stewart and his wife Gloria, penned a letter to the editor of the NYT, which read: 

"In her speech at the G.O.P. convention Monday night, Natalie Harp, a cancer survivor, made reference to the film 'It's a Wonderful Life,' comparing Donald Trump to George Bailey, the main character in the film, played by my father, James Stewart.

"Given that this beloved American classic is about decency, compassion, sacrifice and a fight against corruption, our family consider Ms. Harp's analogy to be the height of hypocrisy and dishonesty," the scathing response concluded.

Washington Post fact checkers have also cast doubt on the truth of Harp's claim about Trump and the Right to Try act, which they say would not have factored in to the treatment she received and the timeline she described in her speech.
