“As part of a treatment plan for prostate cancer, President Biden is currently undergoing radiation therapy and hormone treatment,” the spokesperson said.

In May, the 82-year-old ex-president’s office announced that Biden had been diagnosed with an aggressive form of prostate cancer that had spread to his bones after he experienced urinary symptoms and a prostate nodule was found.

“Cancer touches us all. Like so many of you, Jill and I have learned that we are strongest in the broken places,” Biden, whose son Beau Biden died of cancer in 2015, said at the time in a social media post.

“Thank you for lifting us up with love and support,” he said.
