WASHINGTON (AP) — Hillary Clinton is rolling out proposals to curb the cost of child care for working parents.

Clinton's campaign says she plans to discuss her child care proposals during a stop at a family health center in Louisville, Kentucky, on Tuesday. She aims to ensure no family pays more than 10 percent of its income on child care through a mix of federal subsidies and tax relief.

She's also proposing more spending to boost wages for child care workers and expand home visits by social workers or nurses for new parents.

The Democratic presidential contender holds a commanding lead among delegates against rival Bernie Sanders.

Clinton and Sanders are competing in Tuesday's West Virginia primary. They have races next week in Kentucky and Oregon.
