Former Vice President Kamala Harris responded to news of President Biden’s cancer diagnosis on Sunday, calling her former boss “a fighter.” 

“Doug and I are saddened to learn of President Biden’s prostate cancer diagnosis. We are keeping him, Dr. Biden, and their entire family in our hearts and prayers during this time,” Harris wrote in a post on the social platform X. 

“Joe is a fighter — and I know he will face this challenge with the same strength, resilience, and optimism that have always defined his life and leadership. We are hopeful for a full and speedy recovery,” she continued. 

Harris’s statement comes shortly after Biden’s spokesperson announced the former president had been diagnosed with an aggressive form of prostate cancer. 

“Last week, President Joe Biden was seen for a new finding of a prostate nodule after experiencing increasing urinary symptoms,” according to a statement from Biden’s personal office.

“On Friday he was diagnosed with prostate cancer, characterized by a Gleason score of 9 (Grade Group 5) with metastasis to the bone. While this represents a more aggressive form of the disease, the cancer appears to be hormone-sensitive which allows for effective management. The President and his family are reviewing treatment options with his physicians.”

Well wishes for Biden from Democratic and Republican politicians poured in on Sunday afternoon, including from his former rival President Trump. 

“Melania and I are saddened to hear about Joe Biden’s recent medical diagnosis,” Trump posted on Truth Social. “We extend our warmest and best wishes to Jill and the family, and we wish Joe a fast and successful recovery.”
