(AP) - Glen Campbell's two oldest children want someone besides his wife to make medical and financial decisions for him.

Debby Campbell-Cloyd and Travis Campbell are asking a judge to appoint conservators and a guardian to protect Campbell's interests. They say in a petition filed in Nashville in January that Campbell's wife, Kim, is keeping their father secluded from the rest of the family and won't let them help with his care.

The petition was filed under seal but a copy was sent to The Associated Press. Kim Campbell's attorney refused to comment because of the seal.

Glen Campbell is in the late stages of Alzheimer's disease and lives at a long-term care facility.
