After the show aired, Palin slammed the show, calling it the work of "cruel, cold-hearted people."

In response, Friedman explained that her character should serve as an inspiration to others: "I guess former Governor Palin does not have a sense of humor."

"In my family we think laughing is good," Friedman told the New York Times at the time. "My parents raised me to have a sense of humor and to live a normal life."

And, she was proud of being able to bring representation to her characters onscreen.

"I'm not embarrassed," she continued. "But mostly, it doesn't matter if you have Down syndrome. Really, it just matters to have a different challenge."

Her final onscreen appearance was in the 2019 film Carol of the Bells.
