• Analysis: Promises of an American ‘golden age’ – that conveniently ends with Trump’s presidency

Republicans in the House of Representatives won passage on Thursday of a major bill to enact Donald Trump’s tax and spending priorities while adding trillions of dollars to the US debt and potentially prevent millions of Americans from accessing federal safety net benefits.

The One Big Beautiful Bill Act was approved in the early morning hours along party lines by the slim Republican majority, with 215 votes in favor and 214 against. Its passage ended weeks of negotiations that drew into question the GOP’s ability to find agreement on Trump’s top legislative priority in a chamber they control by just three seats.
