U.S. Senate Republicans passed President Donald Trump's massive tax-cut 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.

In a speech from the White House balcony facing the South Lawn, Trump thanked Republican lawmakers who helped usher the bill to his desk. He touted the tax cuts in the bill, brushing aside criticism of the impact to social programmes such as food assistance and Medicaid.
