Women — and some men — in Congress have been fighting for government child care assistance for almost 80 years. With President Joe Biden's $1.85 trillion social services package, they are as close as they have ever been to winning.

Biden's bill making its way through Congress would put the U.S. on course to providing free prekindergarten, paid family leave to care for children or sick loved ones, and an enhanced child tax credit in a massive expansion of federal support to working families.
