Congress passed a giant tax bill that includes the Senate's SALT changes that allow rich Americans in high-tax states to save money, experts say.

At some 887 pages, the legislation is a sprawling collection of tax breaks, spending cuts and other Republican priorities, including new money for national defense and deportations.

With Sens. Rand Paul and Thom Tillis opposed to the package, GOP leaders can afford only one more defection. And multiple Republicans aren't yet sold on the measure.
