Fellow Democrat Biden said he and his wife, Jill, accompany Carter and his relatives "in prayers and we send you our love".
"We admire him for the strength and humility he has shown in difficult times."Biden tweeted. I hope that "may you continue your journey with grace and dignity, and may God grant you peace".

In recent years, Carter has been treated several times in hospitals, including the time he revealed in August 2015 that he had brain cancer and was undergoing heavy radiation therapy. A disease from which she recovered, against all odds.
During his presidencyCarter was committed to human rights and social justice, which worked well for his first two years. But the administration suffered setbacks, and Carter was relegated to a single term when he was defeated in 1980 by Republican Ronald Reagan.
