Former first lady Rosalynn Carter is in hospice care at home in Plains, Georgia, the Carter Center announced Friday.

The center said the 96-year-old is at home with former President Jimmy Carter, now 99. The Carter family said through the statement that they are “grateful for the outpouring of love and support.”

The family announced earlier this year that the former first lady is suffering from dementia. The former president entered hospice care at home in February.

They have been married for more than 77 years, through his rise from their Georgia farm to his election to the presidency in 1976. After his 1980 defeat, the couple established The Carter Center in Atlanta as a global center to advocate human rights, democracy and public health.

“The best thing I ever had happen in my life was when she said she’d marry me,” Jimmy Carter said, long after leaving the Oval Office.

The couple’s grandson, Jason Carter, described his grandmother in a recent interview as the former president’s “partner No. 1, 2 and 3,” and the former first couple themselves both agreed that she has been the more aggressive political personality of their long pairing.

In Washington, the political press of the late 1970s dubbed Rosalynn Carter “the Steel Magnolia,” reflecting the quiet grace stereotypical of the era’s Southern political wives and a tough core that made her a force on her husband’s behalf and in her own right.
