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 Republican-controlled U.S. Senate narrowly advanced President Donald Trump's, sweeping tax-cut and spending bill on Saturday, during a marathon weekend session marked by political drama, division and lengthy delays as Democrats sought to slow the legislation's path to passage.
