U.S. President Donald Trump's sweeping tax bill failed to clear a key procedural hurdle on Friday, as hardline Republicans demanding deeper spending cuts blocked the measure in a rare political setback for the Republican president in Congress.

The hard-right lawmakers are insisting on steeper spending cuts to Medicaid and the Biden-era green energy tax breaks, among other changes, before they will give their support to President Trump’s bill.

A budget bill, long touted by Donald Trump as the "big, beautiful bill" hit a roadblock on Friday when lawmakers from the president's own party voted against it in congress. Five Republicans joined all Democrats in delivering a stunning setback to President Trump's domestic agenda, demanding deeper budget cuts.
