The Republican package would slash taxes, boost spending on immigration enforcement and the military, and impose steep cuts to Medicaid, SNAP and clean energy funding.

The Tax Policy Center, which provides nonpartisan analysis of tax and budget policy, projected the bill would result next year in a $150 tax break for the lowest quintile of Americans, a $1,750 tax cut for the middle quintile and a $10,950 tax cut for the top quintile. That’s compared with what they would face if the 2017 tax cuts expired.
