U.S. Senate Republicans passed President Donald Trump's massive tax-and-spending bill on Tuesday by the narrowest of margins, advancing a package that would slash taxes, reduce social safety net programs and boost military and immigration enforcement spending while adding $3.

President Donald Trump’s multitrillion-dollar tax and spending package moved closer to reality after it passed the Senate Tuesday.Republican senators altered an earlier version approved by the House to make deeper cuts to safety-net programs such as the Medicaid health insurance for the poor and disabled.

Trump is still saying Social Security benefits won’t be taxed. The reality is that the tax break under discussion is a temporary bonus senior tax deduction whose size depends on which version of the bill makes it into law. The latest version in the Senate includes a $6,000 per person deduction, compared with the House-passed $4,000 deduction.
