tax bill

Republican lawmakers say their plans will save the typical middle class family between $1,200 and $1,400. But polls show only 25 percent to 33 percent of Americans approve of the proposals.

There is still a scramble to lock down enough votes for GOP leaders to pass their overhaul of the nation's tax code. The bill is a work in progress on the Senate floor today.

Some senators want the tax overhaul to come with a built-in trigger: If budget deficits grow, tax cuts will be reversed. But several key senators strongly oppose the idea.

Republican leaders are working to update their long-promised tax overhaul legislation to satisfy enough senators to allow a vote on the legislation as early as this week.

Republican leaders expressed confidence that the measure could pass the Senate. It is likely to face even fewer hurdles in the House, as the GOP aims to pass a tax bill by Christmas.

Even though Republicans promise to preserve the deduction for charitable donations, nonprofits say other proposed changes in the bill could discourage as much as $13 billion in annual giving.
