President Donald Trump celebrated the Fourth of July by signing his massive spending bill that narrowly passed in Congress this week.

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.

The president’s sweeping domestic policy achievement extends his expiring 2017 tax cuts, but could cause millions in the U.S. to lose their health coverage and food aid over the next decade.
