Tennessee lawmakers have approved legislation drastically expanding the number of families who can use taxpayer money on private schools regardless of income.

In one of the most hotly-contested questions in modern Tennessee political history, the legislature narrowly approved a $430 million private-school voucher program that critics say will grow quickly to $1 billion and endanger the state’s budget.

In the first full day of committees during Tennessee's special legislative session, Republicans pushed an expanded school voucher program.

The plan has been discussed for months. On day two of the special session, lawmakers and Tennesseeans on both sides are reacting on Tuesday.
