Democratic vice presidential nominee Joe Biden has canceled his campaign appearances Monday and Tuesday after the death of his mother-in-law Sunday.

Biden spokesman David Wade said Bonny Jean Jacobs, the mother of Biden's wife, Jill, died Sunday after a long illness.

Jacobs was 78 and lived in Willow Grove, Pa. Wade described her as a "homemaker and avid gardener with a lifelong love of reading."

"We appreciate everyone's respect for the family's privacy during this difficult time," Wade said.
