‘I’m sure as hell not giving up:’ Florida First Lady Casey DeSantis talks about breast cancer fight

She made a surprise appearance at the Hernando County Republican Party Lincoln-Reagan Day Dinner, where her husband was keynote speaker.

Florida First Lady Casey DeSantis made her first public appearance on Saturday after it was announced earlier this month that she had been diagnosed with breast cancer.

On Monday, Gov. Ron DeSantis shared a video on his Twitter account of he and and his wife speaking at the Hernando County Republican Party Lincoln-Reagan Day Dinner on Saturday.

In the video, which is about two minutes and thirty seconds long, he calls Casey “the most wonderful person that has stood by me,” and then thanked the crowd for their thoughts and prayers.

He then tells the crowd that she is there in person to thank them herself, which prompts them to give her a standing ovation. After thanking them herself, she says she has been doing a lot of thinking lately.

“There’s a lot that we can be upset about, that we can be sad about -- the direction of our country, the future of our nation, our families, our communities, safety, our children, their education, their futures, our health and our well being. But I tell you one thing that’s for sure -- I’m sure as hell not giving up,” Casey DeSantis said, getting thunderous applause in return.

“When you know in your heart what is right, never, ever, ever, ever give up the fight, ever,” she continued.

She finished her remarks by saying she was stealing a line from her husband: “I have only begun to fight.”
