Bidens, Casey DeSantis and Ivanka Trump offer Kate Middleton well wishes following cancer diagnosis

President Joe Biden and First Lady Jill Biden along with Ivanka Trump and Florida First Lady Casey DeSantis sent Kate Middleton well wishes on Friday after the British Royal announced her cancer diagnosis via social media. 

"Jill and I join millions around the world in praying for your full recovery, Princess Kate," Biden wrote on X, formerly Twitter, while sharing the video announcement originally posted by the palace. 

"You are brave, and we love you. ~Jill," the First Lady followed on X.

"From one mom to another, you’ve got this. If I can beat it, so can you. Have faith, stay strong, and fight like hell. We’re praying for you!," DeSantis wrote on X, alluding to her own battle with cancer in 2021. She announced her diagnosis in October 2021, but after months of treatment and chemotherapy, Florida's first lady was declared cancer-free the following year.

"I am deeply saddened to hear about Princess Kate's diagnosis. Amidst the trials she faces, her strength and grace continue to shine brightly. It's disheartening to see the speculation that has surrounded her, particularly during a time when support and kindness are most needed," Trump shared on X.

"During this challenging period, my thoughts and prayers are with Kate and her family. I hope for her swift and full recovery, and I look forward to seeing her continue to inspire and make a positive impact in the lives of others. Let us all show our support by respecting her privacy and focusing on sending positive thoughts her way."

Trump previously visited Buckingham Palace in 2019 while former President Donald Trump was still in office. All four of the former president's children joined him on his state visit, which included a banquet with various members of the Royal Family.
