Long Term Care Expenses In The USA Is There Some Law That Says Children Have To Pay For Their Parents Nursing Home Care?

In the USA is there some law that says children have to pay for their parents nursing home care? - long term care expenses

Recently I read an article-like, explaining that "the law makes on reducing the budget of 2006," parents for the cost of long-term care of children. Respoisible I thought that only the children when their parents were active in the past five years. Any help would be appreciated.
