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.

At some 887 pages, the legislation is a sprawling collection of tax breaks, spending cuts and other Republican priorities, including new money for national defense and deportations.
