The plan, dubbed "Medicare at Home," focuses on having Medicare cover costs of home care services and nurses as a way for families to help avoid costs of nursing homes. Harris is pairing it with a plan she's already announced that would expand the child care tax credit to up to $3,600, and $6,000 for parents with newborns.

Vice President Kamala Harris on Tuesday announced a plan for Medicare to cover long-term-care services at home, a significant expansion of the program that would be aimed at helping tens of millions of Americans who are caring for aging parents.
