Bonny Jean Jacobs died today at the age of 78. She was the mother of Joe Biden’s second wife, Jill.

Biden put his campaign on hold on Friday to send his son Beau off to Iraq. But yesterday he canceled weekend campaign events when he was advised how ill his mother in law had become. The family rallied round her, and she passed away this morning. The Biden campaign has been suspended until at least Wednesday while the family deals with their grief and buries Bonny Jean.

Jacobs died after battling a long illness. She was predeceased by her husband of 50 years, Donald C. Jacobs, in 1999. The memorial service for Bonny Jean will be on Tuesday.
