President Joe Biden unveiled on Wednesday a sweeping $1.8 trillion plan to expand educational opportunities and child care for families, funded in part by the largest tax increases on wealthy Americans in decades—the centerpiece of his first address to a joint session of Congress.

Called the "American Families Plan," Biden's third major legislative proposal combines $1 trillion in spending with $800 billion in tax cuts and credits for middle- and lower-income families.

The plan would make pre-kindergarten and community college free across the country, extend the child tax credit through 2025 and make permanent an expansion of the earned income tax credit for childless adults with low incomes, provide direct support to families for child care, finance teacher training, and create a national paid family leave program.
