Top Republicans have brushed aside concerns that Donald Trump’s landmark tax bill risks being derailed by his extraordinary clash with Elon Musk as the party closes ranks around the US president. The two men fell out in dramatic fashion on Thursday after a spat triggered by disagreements over the president’s “big beautiful bill” erupted into an all out feud that some feared could scupper the legislation.

At its core, the Republican “big, beautiful bill” is more than just an extension of tax breaks approved during President Donald Trump’s first term at the White House.

The GOP's contentious budget bill narrowly passed in the House, faces dissent in the Senate and has drawn the ire of Elon Musk in a big way.
