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

Flanked by Republican legislators and members of his Cabinet, Trump signed the multitrillion-dollar legislation at a desk on the White House driveway, then banged down a gavel gifted to him by House Speaker Mike Johnson that was used during the bill’s final passage Thursday.

The bill would add $3.4 trillion to the nation’s $36.2 trillion debt. President Donald Trump’s tax-cut package cleared its final hurdle in the U.S. Congress on Thursday, as the Republican-controlled House of Representatives narrowly approved the massive bill and sent it to him to sign into law.
