Winners and losers of a controversial US bill

US President Donald Trump's sweeping tax-and-spending proposal, commonly known as the "Big Beautiful Bill", was awaiting a vote on Wednesday in the House of Representatives after its passage by the narrowest of margins the day before in the Senate.

The House, which narrowly passed the bill last month, now needs to approve the Senate's changes to the bill before it can head to Trump's desk for his signature prior to the July 4 deadline.

The final showdown over the key legislation — which is expected to bring massive changes to taxes, federal spending and regulatory policies — comes following weeks of intense infighting within the Republicans and strong opposition from the Democrats and some business leaders such as Tesla CEO Elon Musk. House Democratic leader Hakeem Jeffries said on Wednesday that every single Democrat will "vote hell no" against the policy package, which he called "one big ugly bill".
