(CNN) - Democratic Vice Presidential nominee Joe Biden is cancelling his campaign events for Saturday and Sunday as his mother-in-law battles a serious illness.
The Senator from Delaware's campaign spokesman, David Wade, put out a statement saying "the campaign has cancelled Sen. Biden's schedule today and tomorrow because of a serious illness in Jill Biden's family. Hospice has advised the Bidens to remain close by, and we appreciate everyone's respect for the family's privacy."
Wade is referring to Biden's wife's mother, Bonny Jacobs, who is in a hospice in Pennsylvania.
Biden was scheduled to speak in Washington D.C. and then attend a fund-raiser in the nation's capitol Saturday night. Sunday he was expected to campaign in Virginia.
