House Republican leaders are scrambling to shore up support for President Trump's massive domestic policy bill amid pushback to the Senate's changes.

The $3.4 trillion legislation would extend tax cuts from Trump’s first term, implement campaign promises such as eliminating income taxes on tips and flood militarized resources to immigration officials.

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 to what they’d face if the 2017 tax cuts expired.
