The US Senate has begun a marathon vote on a sprawling budget that is critical to President Donald Trump's agenda, but the spending plan is hanging in the balance after weeks of fraught negotiations, BBC reported.
Republicans - who control both chambers of Congress - are divided over how much to cut welfare programmes in order to extend tax breaks in the One Big Beautiful Bill Act.
The president's party is sprinting to pass the legislation by this week's self-imposed deadline of the Fourth of July public holiday.
If the measure does clear the Senate, it will have to go back for another vote to the House of Representatives, which passed its own version of the bill last month by a single vote, according to BBC.
