President Donald Trump is slated to use the White House's Fourth of July celebrations as the backdrop for his final victory lap over his massive spending bill.

U.S. President Donald Trump signed into law a massive package of tax and spending cuts at the White House on Friday, staging an outdoor ceremony on the Fourth of July holiday that took on the air of a Trump political rally.

US President Donald Trump is to sign his landmark policy bill into law, a day after it was narrowly passed by Congress. The signing event at the White House on Friday afternoon, coinciding with 4 July celebrations, enacts key parts of the Trump agenda including tax cuts, spending boosts for defence and the immigration crackdown.
