In the early hours of Saturday morning, the Senate passed a sweeping tax overhaul bill in largely party-line vote. Just one Republican, Tennessee Senator Bob Corker, voted against it on deficit concerns. The Congressional Budget Office estimated the bill would cost $1.47 trillion over a decade. Many Republicans continue to say the bill will pay for itself through greater economic growth, despite all analyses to the contrary. The final Senate bill differs from the tax bill passed by the House in mid-November. Those differences now must be reconciled and a final piece of legislation voted on by both chambers.
