The eldest daughter of Al and Tipper Gore, Karenna, has separated from her husband of 12 years, Andrew Schiff, it has emerged.
Karenna, 36, and Drew Schiff, 44, who live in New York and have three young children, "have been separated for a couple of months and are in marriage counselling," two friends of the family, who declined to be named, say.
Mr Gore and his wife announced only last week that they were separating after 40 years of marriage.
The former vice-president, 62, narrowly lost the presidency to George Bush in 2000. A spokesman for his office said it had no comment.
