“Trump’s new budget blueprint, which is also known as a resolution, does three things.
First, it calls for extending the president’s 2017 tax cuts, which would otherwise expire at the end of the year, at a cost of $4 trillion over the next decade. It also makes room for another $500 billion in tax cuts Trump talked about on the campaign trail, such as no tax on tips, for a grand total of $4.5 trillion.
Second, the blueprint greenlights modest spending increases targeted toward immigration enforcement (up to $110 billion), customs and border protection (up to $90 billion) and military involvement in border security (up to $100 million) — top Trump priorities.
And finally, at the behest of conservative deficit hawks, the resolution mandates $2 trillion in spending cuts over 10 years to partially offset new border spending and the trillions in revenue lost to Trump’s tax cuts. (Even then, the new budget would still directly add $2.8 trillion to the deficit.)
For now, Trump’s budget blueprint doesn’t say which programs will be slashed; instead, it instructs specific House committees to cut specific amounts from the programs under their jurisdiction.”
