The changes made to President Trump's big tax bill in the Senate would pile trillions onto the nation's debt load while resulting in even steeper losses in healthcare coverage, the Congressional Budget Office said in a new analysis.

The bill, containing tax breaks and spending cuts, would be a signature achievement for President Trump. But some Republican senators have concerns that have not been resolved.

The legislation would cause the national debt to soar even more than previous estimates, according to new projections released Sunday.
